Why the Stock Market Might Be Broken

Index Funds: Risk, and Rethinking the Market

Index Fund Dilemma: Success and Pitfalls

Imagine a world where the simplest way to grow wealth isn’t through hours of research or tracking stock movements, but by simply buying a piece of the entire market. For millions of investors, index funds have become that golden ticket. Born from a simple idea—track the market, don’t try to beat it—index funds have turned traditional investing on its head. But as the trillions of dollars poured into these passive vehicles continue to rise, questions emerge: Could this be the start of a market bubble? Is the very strategy that has enriched so many now at risk of becoming its own downfall? And what can the crypto world learn from this journey? This article dives into the fascinating history, evolving dynamics, and potential pitfalls of index funds, offering a fresh perspective for those exploring both traditional and decentralized finance.


Why Index Funds Rose to Dominance

Index funds have grown from a niche concept to a dominant force in investing, providing a simple way for individuals to mirror the market’s performance. This idea traces back to the efficient market hypothesis (EMH), which argues that all available information is already reflected in stock prices, making it nearly impossible to consistently outperform the market. Proponents like John C. Bogle, the founder of Vanguard, believed that a low-cost, broadly diversified fund could allow everyday investors to achieve market returns without the guesswork.

The appeal is clear: lower fees, reduced risk through diversification, and a hands-off approach. Over time, this strategy won over investors, leading to a shift from actively managed portfolios to passive index funds. Yet, as more money flows into these funds, new theories like the inelastic market hypothesis suggest that passive investing may be distorting market prices. Critics argue that by continuously funneling money into large-cap stocks, index funds might be inflating valuations and amplifying the risk of a future market correction. As we explore these dynamics, we’ll also consider how similar patterns might play out in the rapidly evolving world of crypto and blockchain.


Critical Analysis

Strengths of the Video’s Arguments

  1. Index Funds Simplify Investing for the Masses: One of the video’s strongest points is how index funds have democratized access to the stock market. By offering a straightforward way to match market returns, index funds have made investing accessible to those who might not have the time or expertise to pick individual stocks. The historical growth of Vanguard and similar funds illustrates how investors embraced the simplicity and cost-effectiveness of this approach.

    • Example: From 1980 to 2023, the percentage of Americans holding stocks rose from 13% to 61%, thanks largely to the rise of index funds and 401(k) auto-enrollment programs.
    • Why It Matters: This shift has allowed millions to participate in market gains, contributing to a more financially secure retirement for many.
  2. The Cost Advantage of Passive Investing: The video highlights how index funds save investors money through lower fees. Unlike actively managed funds that require a team of analysts, index funds simply track an index, keeping costs down.

    • Example: While active funds may charge management fees of 1.3-2.5%, index funds often range between 0.2-0.5%.
    • Why It Matters: Over decades, these savings compound, making a significant difference in long-term investment outcomes. This is a critical advantage in both traditional finance and emerging crypto ETFs, where lower fees can translate to higher returns.
  3. Challenges to the Efficient Market Hypothesis: The video raises thought-provoking questions about the validity of EMH, particularly in today’s market where passive investing dominates. It introduces the inelastic market hypothesis, which suggests that the influx of passive investments may cause disproportionate changes in stock prices.

    • Example: According to this hypothesis, every $1 invested in the stock market could result in a $5 increase in market value.
    • Why It Matters: This potential distortion challenges the idea that markets are always accurately priced, implying that passive strategies might not be as risk-free as they appear.

Potential Weaknesses of the Video’s Arguments

  1. Overemphasis on the Risks of Passive Investing: While the video effectively highlights the potential dangers of passive investing, it may overstate the threat of a market collapse due to index funds. Many analysts argue that active managers still play a substantial role in price discovery, as they are responsible for most daily stock trading.

    • Counterargument: A report by Vanguard suggests that 95% of daily stock trades are still conducted by active managers, implying that they continue to have a significant influence on stock prices.
  2. Simplification of Active vs. Passive Debate: The video paints a binary picture of active and passive investing without fully addressing the nuances. For instance, some investors use a combination of both strategies, allocating a core portion of their portfolio to index funds while making tactical investments in select stocks.

    • Alternative Viewpoint: This hybrid approach can offer a balance between the lower costs of passive investing and the potential for higher returns through active management.
  3. Limited Discussion on Market Corrections: The video touches on the risk of a market correction but doesn’t fully explore the historical context of past corrections and their causes. It would be valuable to consider whether similar patterns from past corrections, such as the dot-com bubble or the 2008 financial crisis, could inform current concerns about index fund-driven distortions.

    • Nuance: Understanding how past corrections played out could provide insights into whether current fears are overblown or a genuine cause for concern.

Connections to Cryptocurrency and Blockchain

The rise of index funds in traditional finance offers intriguing parallels to the emergence of index-like products in the crypto space. Just as the S&P 500 provides a snapshot of the U.S. economy, crypto indexes like the DeFi Pulse Index (DPI) aim to capture the growth of decentralized finance projects. These products enable investors to gain diversified exposure to the crypto market without having to pick individual tokens, mirroring the passive investment appeal of stock index funds.

Application in DeFi: In the world of decentralized finance, the concept of passive investment takes on a new form through products like yield farming and liquidity pools. Platforms like Uniswap allow users to passively earn returns by providing liquidity to trading pairs. This mirrors the passive nature of index funds but introduces new risks, such as impermanent loss, that traditional investors might not be familiar with.

Challenges in a Decentralized Context: Unlike traditional index funds, crypto indexes face challenges such as regulatory uncertainty, extreme volatility, and a lack of standardized metrics. The inelastic market hypothesis might be even more applicable in crypto, where large trades by whales can dramatically impact prices due to lower market liquidity. For example, a single sell-off by a major holder of Bitcoin can ripple through the entire market, causing a chain reaction of price movements.

Potential for Innovation: DeFi projects like Balancer are experimenting with dynamic index funds, where the composition of assets can automatically rebalance based on market conditions. This level of automation could address some of the criticisms of passive investing, providing a more responsive approach that adapts to market shifts.


Broader Implications and Future Outlook

The dominance of index funds has reshaped the landscape of traditional investing, and their influence extends far beyond the financial sector. As passive investing continues to grow, it raises fundamental questions about market efficiency, price discovery, and even the role of capitalism itself. If markets become more sensitive to the flows of passive capital, we might see more frequent and severe market corrections, challenging the assumption that “the market always goes up.”

Impact on Society: The shift towards passive investing has broader societal implications, particularly for wealth distribution. While index funds have democratized access to market returns, they have also contributed to the concentration of capital in large, well-established companies. This could make it more challenging for smaller businesses to access capital, potentially stifling innovation.

Predictions for the Future: As blockchain technology matures, we may see a blending of traditional and decentralized finance, with crypto indexes becoming a mainstream investment vehicle. The emergence of Bitcoin ETFs in regulated markets is a sign of this convergence. However, the lessons from the traditional stock market—like the risks of overconcentration and market distortions—should guide the development of these products in the crypto space.

The Role of AI and Automation: AI-driven trading strategies could further change the landscape, enabling more sophisticated forms of passive investment that respond to market signals in real time. This could mitigate some of the risks of traditional index funds while introducing new complexities around data privacy and algorithmic biases.


Personal Commentary and Insights

From my perspective, the rise of index funds serves as a powerful reminder of how simplicity can disrupt an industry. What started as a contrarian idea has become a pillar of modern investing, helping millions achieve their financial goals. Yet, the risks highlighted in the video are worth considering, especially for those of us who see parallels in the crypto space. Just as index funds reshaped the stock market, decentralized protocols and automated trading strategies could transform how we think about investment in the coming decades.

However, the idea that passive investing alone could destabilize markets seems too alarmist. History has shown that markets have a way of correcting themselves, often through the actions of active investors who step in when prices become too detached from reality. For crypto enthusiasts, this is a valuable lesson—one that reminds us to remain vigilant about market trends while embracing innovation.


Conclusion

Index funds have revolutionized investing, offering a straightforward path to market returns while raising new questions about market stability. As we look to the future, the interplay between passive and active strategies, and the lessons from traditional markets, will shape the next phase of financial evolution. For those exploring crypto, understanding these dynamics is crucial. After all, the world of finance, whether centralized or decentralized, thrives on a balance between simplicity and complexity. As you continue with the Crypto Is FIRE (CFIRE) training program, keep these insights in mind—both markets, and your journey through them, are only as strong as your understanding of the forces at play.

The Rise of Index Funds: A Game-Changer or a Looming Risk?

Overview: This lesson explores the journey of index funds, a revolutionary investment strategy that has shaped the modern financial landscape. Index funds have become the go-to investment for many, offering a low-cost and seemingly straightforward way to participate in the market. But behind their appeal lies a complex dynamic that has raised questions about the stability of the stock market itself. We’ll delve into the roots of index funds, their relationship to the efficient market hypothesis, and consider how similar principles could apply—or misfire—in the world of cryptocurrencies. This lesson is part of the Crypto Is FIRE (CFIRE) training plan, designed to help you connect traditional finance insights with the evolving crypto landscape.


Core Concepts

  1. Index Fund

    • Traditional Finance: An investment fund designed to replicate the performance of a specific market index, like the S&P 500.
    • Crypto World: Similar strategies can be seen in crypto index funds, which track baskets of cryptocurrencies rather than stocks.
    • Importance: Understanding index funds helps newcomers recognize how passive investment strategies can influence market dynamics.
  2. Efficient Market Hypothesis (EMH)

    • Traditional Finance: A theory suggesting that stock prices fully reflect all available information, making it impossible to consistently beat the market.
    • Crypto World: While less established, some argue that efficient markets could eventually develop in crypto as transparency improves.
    • Importance: Grasping EMH helps investors understand why index funds are often recommended as a way to match market returns.
  3. Inelastic Market Hypothesis

    • Traditional Finance: A newer theory proposing that the market reacts more dramatically to investments than previously thought, amplifying price movements.
    • Crypto World: Crypto markets, being highly volatile, might show similar sensitivity, especially during large trades or whale activity.
    • Importance: Recognizing this concept is vital to understanding why sudden shifts in market sentiment can lead to sharp price changes.
  4. Passive vs. Active Management

    • Traditional Finance: Passive management seeks to match market performance, while active management attempts to outperform it through stock selection.
    • Crypto World: In the crypto space, passive strategies may involve holding a diversified portfolio of major coins, while active management focuses on trading to exploit market inefficiencies.
    • Importance: This distinction helps investors decide whether to pursue a hands-on approach or take a more set-and-forget strategy.
  5. Market Corrections

    • Traditional Finance: A market correction is a decline of 10% or more in the value of a stock market index after a recent peak.
    • Crypto World: Corrections in the crypto market can be even more pronounced due to higher volatility and less mature market structures.
    • Importance: Knowing about corrections helps investors prepare for inevitable market downturns and avoid panic selling.

Key Sections

1. The Birth of Index Funds: A Simple Idea with Big Impacts

  • Key Points:
    • Index funds were introduced to provide a low-cost way to match market returns.
    • The first index fund, created by John C. Bogle in 1974, was initially met with skepticism.
    • Over time, index funds became mainstream as they consistently outperformed many actively managed funds.
  • Detailed Explanation: Index funds simplify investing by allowing individuals to buy shares of a fund that tracks major market indices like the S&P 500. This concept relies on the belief that it’s difficult to consistently beat the market. By holding a small piece of many companies, investors can enjoy the average growth of the entire market.
  • Crypto Connection: The idea of spreading risk across a broad set of assets is gaining traction in the crypto world, with projects like index tokens that bundle various digital assets. For example, the DeFi Pulse Index (DPI) tracks a group of DeFi tokens, offering exposure to the sector without the need to pick individual winners.
  • Importance: This section highlights how a simple idea can revolutionize an industry, much like how blockchain aims to reshape the financial sector.

2. Efficient Market Hypothesis: The Backbone of Passive Investing

  • Key Points:
    • EMH suggests that stock prices reflect all available information.
    • If true, no one can consistently outperform the market.
    • Index funds emerged as a logical investment choice based on EMH.
  • Detailed Explanation: EMH proposes that predicting stock movements is futile because every bit of information is already factored into the price. This led to the creation of index funds, where instead of trying to outguess the market, investors could simply buy the entire market.
  • Crypto Connection: While crypto markets are young and often inefficient, the potential for them to become more efficient as transparency increases could make index-style investing more viable. Tools like CoinMarketCap provide near-instant data, making crypto markets quicker to react than traditional stock markets.
  • Importance: This concept is crucial for understanding the rationale behind many passive investment strategies, including in the crypto space.

3. The Rise of Passive Investing: Opportunities and Concerns

  • Key Points:
    • Passive investing has become the dominant strategy, with more money in index funds than actively managed ones.
    • Some analysts worry that passive investing is distorting stock prices.
    • Concerns include potential overvaluation and market instability.
  • Detailed Explanation: As trillions flow into index funds, the market may be driven more by passive inflows than individual stock performance. This could lead to a scenario where prices are not reflective of a company’s true value, potentially creating bubbles.
  • Crypto Connection: In crypto, the rise of passive investment vehicles like crypto ETFs could have similar effects, concentrating influence on the largest coins like Bitcoin and Ethereum. This could potentially marginalize smaller projects, similar to how large-cap stocks dominate the S&P 500.
  • Importance: This section explores the potential downsides of a dominant strategy, a perspective that’s equally important for those exploring passive investment options in the crypto world.

4. Inelastic Market Hypothesis: Rethinking Market Dynamics

  • Key Points:
    • The inelastic market hypothesis suggests that each dollar invested affects the market more than previously thought.
    • This could lead to faster market movements and larger swings.
    • The theory challenges the long-held beliefs of EMH.
  • Detailed Explanation: Traditional thinking assumed that individual investments had a negligible impact on the market’s overall value. But new studies suggest that passive inflows into index funds may be amplifying market movements. This means that a sudden shift in sentiment could cause dramatic price changes.
  • Crypto Connection: The crypto market, known for its volatility, might operate similarly. Large trades, often by so-called whales, can cause rapid price changes, highlighting how liquidity can impact price dynamics.
  • Importance: Understanding this helps investors grasp the volatility of markets and prepares them for rapid changes, whether they’re investing in stocks or digital assets.

5. Passive Strategies vs. Active Management: Which One Wins?

  • Key Points:
    • Passive strategies offer lower fees and often better returns than actively managed funds.
    • Actively managed funds still attract those seeking above-average returns.
    • The debate between active and passive investing is ongoing.
  • Detailed Explanation: While passive investing has gained popularity, active management still has a place for those willing to take on more risk in hopes of achieving outsized returns. Actively managed funds rely on research and analysis to pick stocks, whereas passive funds follow the market’s ebb and flow.
  • Crypto Connection: In crypto, active management can involve timing trades to exploit price swings, while passive strategies might focus on holding coins through volatile periods. For instance, a passive investor might hold Bitcoin and Ethereum, while an active trader might jump between tokens based on market trends.
  • Importance: This section helps learners understand the trade-offs between effort, cost, and potential rewards, a key consideration in both traditional and crypto investing.

The Crypto Perspective

In each section, we’ve highlighted how traditional investment principles like index funds, passive management, and market theories can find their counterparts in the crypto world. Whether through emerging crypto index funds or understanding how market hypotheses might play out in a decentralized ecosystem, this lesson bridges traditional finance with the innovative potential of blockchain.


Real-World Applications

  • Historical Context: The rise of index funds in the 1970s mirrors the current interest in crypto index products like Bitwise 10 and DeFi Pulse Index.
  • Crypto-Specific History: Crypto ETFs, like the Bitcoin ETF, have faced regulatory challenges, similar to the early struggles of index funds in gaining acceptance.

Key Takeaways

  1. Index funds provide a low-cost way to gain broad market exposure, making them ideal for beginners.
  2. The efficient market hypothesis supports passive investment, but newer theories like the inelastic market hypothesis challenge its assumptions.
  3. Passive investing can influence market stability, a consideration for both stock and crypto investors.
  4. Active management may outperform in niche areas, but it’s riskier and more costly.
  5. Understanding market dynamics is key to navigating volatility, whether in stocks or cryptocurrencies.

Discussion Questions and Scenarios

  1. How might the inelastic market hypothesis apply to crypto markets with lower liquidity?
  2. Compare the volatility of stock index funds with that of a diversified crypto portfolio.
  3. Why might an investor choose a crypto index fund over actively trading individual tokens?
  4. If the stock market corrects due to passive investment, what might a similar correction look like in the crypto market?

  5. How could decentralized finance (DeFi) impact the traditional concepts of passive vs. active investment?

Read Video Transcript
If you’ve ever thought about investing your money,  you’ve probably heard this one piece of advice on where to put it.  I’ll be very simple.  Under the conditions you name, I probably have it all in a very little.  I told you.  Articles, books, influencers, and my high school econ teacher  have increasingly promoted this special place to put your money.
 Definitely don’t do investing and just be willing to.  Statistically, this is the simplest way to build wealth for probably 99% of investors.  And slowly, American workers have funneled trillions of dollars into this investment vehicle.  But its success is built on a 50-year-old theory of how the world works.
 And that theory might be off.  By a factor of 500.  For the first time ever, funds that simply track large swaths of the market,  like the  stocks in the S&P 500, now have more money invested in them than actively managed portfolios.  But as money continues to funnel in, some analysts are getting worried.
 People joining passive funds might be overvaluing stocks and could be leading the market towards  a massive correction.  So should we keep going this direction?  Let me step back for a second. The reason I got into this story was because of this chart,  which isn’t that different from this one or this one.
 These are graphs that track  the overall growth of the stock market and they’re going up very fast, almost  too fast. And I’m invested in the stock market, so obviously I want the stocks to go up,  but I’m also skeptical.  Why is this happening?  This is a story of  index, index, index, index, index funds.  How they slowly gobbled up the stock market  and might be based on a giant lie.
 50 years ago, index funds didn’t exist,  but slowly they’ve gained their evangelists. One of the first people to pump index funds didn’t exist. But slowly, they’ve gained their evangelists.  One of the first people to pump index funds to me was my high school economics teacher.  So I’m going to talk to him about why I think they’re so good.
 Hello.  There he is.  What’s up, man?  How are you?  Good to see you.  Thank you again for meeting with me.  Hey, it’s my pleasure.  It’s awesome.  So I want to just ask you the biggest question.  Why do you think index funds are a good investment? Well, there’s an awful lot of volatility in the market.  So the idea for an index fund comes from this long debate about what actually makes the stock market go up and down.
 As long as the market has existed, there have been countless theories trying to answer that one question.  Because if you can figure that out, you can make a ton of money.  And in the 1960s, economists popularized a theory called the efficient market hypothesis  that became a foundational belief behind modern investing.
 Could you start by describing what the efficient market hypothesis is?  A giant lie.  All right, that wasn’t helpful for you. Sorry.  The efficient market hypothesis just means that the current price reflects as much information  as could be obtained in an economically efficient manner.  And therefore prices are rarely wrong by all that much.
 Explain it another way, the efficient market hypothesis is like bidding on something you can’t entirely see.  Hey Bitter Bitter, today we’re auctioning off whatever’s inside of this box.  Hey Bitter Bitter, that’s a tail!  Oh, I’ve seen this before, it’s gotta be an elephant.  $500.  That good with you?  Sold for $500.
 We’ve got 24 million more of these folks for the right price.  20 more sold for $500.  $4.99.  Oh, we’ve got an update.  The object in the box seems to have  a bitter bitter leaf on it.  Uh-oh, sounds like a tree to me.  $300, 500, 500, 475, 470, 400, 400, oh, fine.  Sold for $300, $300, 300 is sold, 300 sold, 301 sold.
 As you can see, the price of the box stock was immediately updated $300, $300, $300 sold, $300 sold, $301 sold.  As you can see, the price of the box stock was immediately updated to whatever new information came out.  It’s basically impossible to predict what would happen next.  Oh, hey, new information.
 That feels like gold to me.  600, 900, 1,000, sold.  So if this hypothesis is true,  no one, neither Warren Buffett nor you and I, can reliably  beat the market, because doing so would require predicting the future.  But if every stock is updated with new information, the most efficient way to invest would be  simply to buy the market as a whole.
 And that doesn’t guarantee the value will go up, but if it does, which it has historically,  then you’ll get as good of a return as anyone.  But how do you follow the market?  The most popular way to track the stock market is through an index, like the S&P 500, which  takes the stocks from 500 to the largest US companies, weighs them by their market cap,  then combines them into one number.
 If the number goes up, those 500 companies’ stocks are also generally going up.  If it goes down, they’re generally going down.  So in the early 1970s, people tested this theory and compared their individual returns  to the S&P 500.  They found that over time, the S&P basically always wins out.  But there wasn’t an easy way to actually invest in the S&P 500 itself.
 So in 1974, after the idea had been floating around for a while,  this guy named Paul Samuelson writes in the Journal of Portfolio Management that someone  should just make a portfolio that tracks the S&P 500. So the idea is essentially to ride in the  backs of all the investors actively working to figure out where to put their money and just  putting in the same places. And by chance, this other guy named John C.
 Bogle, who just started  a new mutual fund called Vanguard,  read this article and thought it was a great idea. So he makes one.  By buying all of the companies in the S&P 500 in the same proportion, Vanguard makes a single fund  that gets the same returns as the S&P 500.
 And now you, an individual person, can buy a piece of that  fund and take that portion of the returns. The first index fund.  Bogle thinks this is the next big thing, but others don’t.  In 1976, the fund IPOs with a goal of $150 million investment and gets $11 million.  Meanwhile, opposing fund managers who get money through fees try to kill indexes before  they take any of their clients.
 One famous poster made by an investment group read, index funds are un-American,  arguing against the conformity  of just thoughtlessly following everyone else.  But over time, the logic of index funds wins out.  According to a 2020 analysis,  89% of all domestic funds underperformed the S&P 500  in the last 15 years.
 There’s no 20 year period of time  where the S&P 500 has gone down.  Right. So over that long period of time, yeah, it’s kind of true.  Like the market does only go up.  Sometimes people do better.  But over time, because it’s so hard, if not impossible to predict the market, the  likeliest success is the average.
 I can’t believe how much money I have.  And my starting salary in 1992 was $13,900.  And I’m probably gonna retire with a few million dollars.  That’s just, it blows my mind away.  And buying an index fund can be even cheaper  than an actively managed fund  that has the same exact stocks,  because there’s not a team of analysts you’re paying  to decide what stocks to include.
 That’s allowed companies like Vanguard to charge very low fees to buy into their funds. Across the market, index funds tend  to charge between 0.2 and 0.5% of the cost of the fund to invest, while actively managed funds charge  upwards of 12 times more, with rates between 1.3 and 2.5%.
 So in a sense, you can beat the market  with an index fund, because as John C. Bogle  would say, you get what you don’t pay for. So while many people pay big fees to get market  results, people invested in index funds pay smaller fees and thus get more of the returns.  From 1980 to 2023, the percentage of Americans holding stocks went from 13% to 61%, which  was fueled by the rise of 401 auto enrollment and  companies like Fidelity that enabled regular people to invest.
 And now tens of  trillions of dollars are sitting in index funds reaping the rewards of a  great strategy. But not everyone thinks so.  If we believe the efficient market hypothesis, the answer has to be that this line is just  what things are worth.  And we’d also assume that the giant fluctuations are simply due to tons of people individually  making tiny little adjustments based on their own analyses.
 Generally, economists assume a marginal $1 invested into the market had nearly no impact,  perhaps a cent.  But a study from 2021 challenges this notion.  This is one of the guys who wrote it.  My name is Xavier Gabex.  I’m French. So I’m a professor of economics at Harvard University.  In his study, he and his co-author identify a system distinct from the efficient market.
 Most investors just stay on the sidelines.  They don’t participate or they do participate in a very, very,  not particularly thoughtful and attentive way.  This is a big realization.  The auction scenario assumes that the bidders  actually care about what’s in the box  and how much it’s worth.  But the way a lot of non-professional investors invest today  doesn’t really make a difference.
 Hey, what’s up?  Just got my paycheck.  How much for one share?  $500.  Sweet, cash it. It’s payday. Deal share? Um, $500. Sweet, cash it.  It’s payday, deal me in two.  $600, works for me.  One more for me.  Um, I feel bitter, bitter bad, but $800?  Great, that means I can get two.  Through the rising popularity of index funds  and other passive investment vehicles,  more and more people are simply piling money  into the stock market,  regardless of how much a stock is really worth.
 And according to Xavier and his co-author Ralph Koijens in Elastic Market Hypothesis,  this money coming in is inflating prices much faster than previously believed.  The surprise is how big the effect is.  The stock market is like a bizarre machine where you invest $100 in the machine  and the machine is worth $500 more.
 And of course it’s symmetric for buys and sells.  So for every $1 that goes into the market, the overall value of the market goes up $5.  And for every $1 that goes out of the market, the overall value goes down $5.  It’s a hypothesis because it’s not a proven theory.  But if it’s true, this could mean that the market is moving at least 500 times as fast  as we previously thought under the efficient market hypothesis.
 So what are the consequences of that?  Well, this means that the market could be overvalued.  And if enough people come to believe that that’s the case, investors will sell their shares, which would send the prices of stocks down and cut the value of the investments many people have in the market.  And given what the inelastic market hypothesis says about how the market works, this process could happen very fast.
 Beyond volatility, others worry index funds are  overvaluing the largest companies as they systematically inject money into them. And with  huge amounts of money under their management, some, including the founder of Vanguard, rest in  peace, worry that companies like it are becoming too large and a significant portion of some  companies’ stocks are owned by index funds.
 But to push back on this charge, most people don’t think indexes are a problem.  At least not yet.  In response to fears that passive investors are somewhat mindlessly paying whatever the  market asks, a representative from Vanguard says passive investors have a tiny impact  on how stocks are valued.  A report by Vanguard found that at least 95% of the stocks bought and sold in a day  are by active managers, suggesting prices are mostly determined by people who are well-informed.
 So that would change the auction scenario to be more like this.  Hey, what’s up? Just got my paycheck. How much for one share? Based on our analysis,  we believe the value is $312.42. Cash it. If this is true, there’s a lot less to worry about.  But Mike Green would urge us to not downplay the impact  of quote-unquote passive investors.
 Even though they’re supposedly just following the market,  they are still buying and selling,  which affects the pricing of stocks.  If you actually believe in the theories of passive,  you have to accept that it is distortionary  for you to decide to do anything in the market.  Still, if you ask a lot of investors, they’ll scoff at these worries.
 My econ teacher is still pumping indexes.  I tell young people and I teach this in my personal finance program.  Start early. Save every month.  Don’t touch that money and just put your money into a stock index mutual fund.  Always works.
 When I asked a certified financial planner if he knows any doubts about index funds,  he said,  People have doubts about index funds.  That’s interesting.  I don’t know too many people like,  No, you gotta go active management is the only way to go.  I’m trying to give you an answer on that one.  I don’t think I have one.  And Xavier still thinks index funds are the best move for the average investor.
 The guy in charge of all of Vanguard’s equity index trading was a bit more tempered and said past performance is not indicative of future  performance. But most angles still support indexes. Returns continue to increase, American businesses  have expansive global impact, and people seem bullish on their investments.
 And even if the  stock market does end up going down, many would argue indexes are still the best way to distribute  your risk. At the end of the day, the stock market is a lot of things.  It’s a marker of companies and their practices,  it’s a measure of hope for a better future,  and it’s a function of people’s fundamental fears.
 And as long as the assumptions driving the market  continue to lead the stock market up a hill,  investing in index funds might still be the best move.  After all, if the market moves up and you’re not invested,  you’ll miss out on money. So are you dancing while the music is playing?  Unfortunately, you have to, right?  But eventually the music might stop or get quieter. So there’s an argument to reducing your risk.
 The market doesn’t exist for retirement. The market exists to facilitate the addition of  capital at an appropriate marginal cost. And so when we break those systems,  I don’t think we should be the least bit surprised  that capitalism itself is threatening to break.  Ultimately, I’m not saying the stock market’s going up  or going down, but I hope this video leaves you  with one insight.
 50 years ago, a guy made a fund that couldn’t be beat.  Since, this simple idea has taken a hold  among many investors, and for many, it’s worked.  But the stock market is not guaranteed to do anything.  As much as we can break it down and average it, there’s nothing ensuring that the stock  market will go up forever, other than through the faith of investors.
 So if you’re investing, all I hope for you is that you understand why.  Maybe it’s because someone told you to.  Maybe it’s because you believe in the masses.  But even if you’re investing passively,  be a little bit less passive of a passive investor.  Choke, choke, choke, choke, choke, choke, choke, choke,  choke, choke, choke, choke!  Man, this really gets my voice going.
 I’m gonna lose it.
