Week 29 Day 2: FOMO: The Most Expensive Emotion in Investing
Fear of missing out drives investors into overvalued assets at the worst possible time. When your Uber driver is talking about crypto returns, when your neighbor brags about their meme stock gains, when everyone is getting rich except you -- that is when FOMO is most dangerous.

Bitcoin at $60,000 in late 2021: 'Everyone is making money, I need to buy!' Bitcoin at $16,000 in late 2022: 'Crypto is dead, I am staying away.' This is FOMO in action -- you buy at the top because the excitement is irresistible, then refuse to buy at the bottom because the fear is equally irresistible. The result: buying high, selling low.
FOMO case studies: Dot-com bubble (2000): millions of Americans opened online brokerage accounts in 1999-2000 to buy tech stocks after watching others get rich. The average retail investor entered the NASDAQ near its peak of 5,000. It crashed to 1,100. It took 15 years to recover. Meme stocks (2021): GameStop rose from $4 to $483 in weeks. Millions of new Robinhood users bought near the top, driven by Reddit hype and FOMO. Most lost money as the stock crashed back to $40. Crypto (2021): Bitcoin, Ethereum, Dogecoin -- retail investors flooded in as prices hit daily all-time highs. 73% of retail crypto investors who entered during the 2021 bull market lost money (Bank for International Settlements, 2023). The antidote to FOMO: (1) Remember that by the time 'everyone' is talking about an investment, the easy money has been made. (2) Stick to your automated plan. Your $500/month into VTI is quietly beating most FOMO-driven traders. (3) Accept that you will miss some opportunities. Trying to catch every wave guarantees you will catch the bad ones. (4) If you have FOMO about a specific investment, allocate a maximum of 5% of your portfolio to it. This satisfies the itch without risking your financial future.
FOMO in financial markets is driven by the interaction of several cognitive biases: social proof (Cialdini, 1984), herding (Banerjee, 1992), regret aversion (Loomes and Sugden, 1982), and the availability heuristic (Tversky and Kahneman, 1973). Social media has amplified FOMO by making investment gains highly visible and salient. Cookson, Engelberg, and Mullins (2023) showed that Twitter (X) investment discussions are dominated by positive sentiment (gains are shared 3-4x more frequently than losses, due to self-enhancement bias), creating a distorted picture of expected returns. Barber, Huang, Odean, and Schwarz (2022) found that Robinhood users exhibited strong herding behavior: stocks featured on Robinhood's 'Top Movers' list experienced 20x normal buying activity, followed by significant negative returns over the subsequent month. The mechanism: FOMO causes investors to chase positive past returns, buying after prices have risen. This is the behavioral driver of the momentum anomaly's reversal: momentum strategies profit from gradual incorporation of information, but FOMO-driven overreaction pushes prices above fundamentals, leading to eventual reversal. The protection protocol: pre-commit to your investment plan (specifying assets, amounts, and schedule) and add a 'cooling off' rule: any deviation from the plan requires a 72-hour waiting period and written justification. This System 2 intervention disrupts the System 1 FOMO response.
