What Is FOMO in Trading? Meaning, Real Examples and What the Data Show

FOMO in trading, the fear of missing out, is the urge to buy because a price is running without you, or to jump into a trade you had not planned because everyone else seems to be making money. It is not a rule or an indicator, but a reason for a decision: the trade is taken because of the move, not because of a plan. This page shows what surveys and research say about it, two dated examples of FOMO markets, and what happened after buying an extended price on three real series.

What does FOMO mean in trading?

Three marks of a FOMO trade: the entry comes after a large move rather than at a level chosen in advance, the position size or the risk is larger than usual, and there is no defined exit. The same fear works on the way out: selling a winner too early because a pullback feels like losing what you had. The emotions often drawn along a market cycle, from optimism to euphoria and then to fear, are a popular picture rather than a measured sequence, but they describe the moment FOMO is strongest: near the top of a fast rise. Greed and fear as market forces are covered on fear and greed.

What surveys and research say

• Self-reported FOMO. In a 2023 survey by the FINRA Investor Education Foundation and the CFA Institute of Gen Z investors in the United States, half (50%) said they had made an investment driven by fear of missing out; 48% said they learn about investing and finances primarily through social media.
• Attention drives buying. Barber and Odean (2008) "test and confirm the hypothesis that individual investors are net buyers of attention-grabbing stocks, e.g., stocks in the news, stocks experiencing high abnormal trading volume, and stocks with extreme one-day returns." A big move is itself what draws the buyers.

Two FOMO markets, with what followed

Both are chosen with hindsight, which makes them look like obvious tops. The test below asks the fairer question: across all bars, not just famous ones, how did buying an extended price turn out?

Does chasing a move lose money? What real bars show

Rule: a chase entry is a close at least 2 average true ranges (14 bars) above the 20-bar simple moving average, our definition of a stretched price. We compared the return over the next 20 bars (4 weeks on the weekly series) after those closes with the return after all bars. Series: Bitcoin daily over our whole history, entries from September 5, 2017 (the first close with both a 20-day average and a 14-day ATR) to October 8, 2026, the last close with 20 later days before October 28, 2026; the S&P 500 ETF daily (dividend-adjusted), entries from February 1, 2021 to September 30, 2026; and Bitcoin weekly, entries from the week of January 1, 2018 to the week of September 21, 2026, with the last weekly bar the week of October 19, 2026. Chase closes come in runs, so we also count episodes: runs separated by more than one holding period.

The results go both ways. On the S&P 500 ETF, chase entries did a little worse than the average bar; on Bitcoin, daily and weekly, they did better, mostly during long rises. On daily Bitcoin, 146 of the 477 chase closes came in its three longest episodes: 43 from October to December 2017, 42 from April to June 2019, 61 from October 2020 to January 2021. On weekly Bitcoin, 65 of the 96 did: 18 from April to August 2019, 25 from October 2020 to April 2021, 22 from October 2023 to April 2024. The single weekly chase close of January 1, 2018 was followed by a 49% fall in four weeks. The period matters as much as the rule: on daily Bitcoin from March 27, 2025 only, the 54 chase closes averaged −0.01% over 20 days, against +0.47% for all 561 bars. With 10 to 36 independent episodes, none of these differences is reliable. The data do not support the idea that buying a stretched price always loses; they do show that the outcome of a chase is far from certain.

How to deal with FOMO

• Write the plan before the market opens. Entry level, stop and size; a move you did not plan for is not a trade. A trading plan template helps.
• Compute the risk before the order. Distance from entry to stop, times the size, as a share of the account. If the number is larger than your usual risk, reduce the size or skip the trade; see position size.
• Wait one bar. If the urge comes from a fast move, waiting for the next bar to close costs little and removes the most impulsive entries.
• Limit the noise. If posts about other traders' gains push you into trades, read them after the session, not during it.
• Keep a journal. Note when you broke the plan and how those trades ended, as described on tracking trading performance. Discipline in general is covered on patience and discipline, and trading too often on the dangers of overtrading.
