Fear of Missing Out in Trading: What It Actually Is (And Why It’s Not About the Trade)

TL;DR: FOMO in trading is not about missing a move. Research by Andrew Przybylski at Oxford links it to unmet psychological needs: autonomy, competence and social connection. The brain doesn’t distinguish between “the tribe is eating and I’m not” and “that Discord group is up 30% on a coin I didn’t buy.” Both can feel like being left out of the group. This guide explains what’s going on, what it means for your trading, and why professional traders eventually develop the opposite of FOMO, sometimes called JOMO.

Every trader has made a FOMO trade. Maybe it was a stock you watched set up correctly, hesitated on, then chased after it broke out 4% in 20 minutes. Maybe it was a crypto you saw on someone’s feed at 11 PM, already up 40%, and you bought anyway because “this one feels different.”

The trade often doesn’t work. And yet the impulse comes back, identically, the next time.

This is not a strategy problem. It is not a discipline problem in the conventional sense. It is a trading psychology problem, specifically, a social survival alarm going off in a brain that was never designed for financial markets.

After 20 years coaching institutional tradersI can tell you that the traders who finally overcome FOMO almost always start by understanding what it actually is, neurologically, psychologically, and in terms of what their real unmet needs are. Because until you address the actual source, every rule you write down is fighting the wrong thing.

What FOMO Actually Is: The Oxford Research

The psychological construct of FOMO was first formally operationalized by Andrew Przybylski and colleagues at Oxford in a 2013 study published in Computers in Human Behavior. They defined it as “a pervasive apprehension that others might be having rewarding experiences from which one is absent.”

The researchers developed a 10-item FOMO scale and found something that matters deeply for traders: people who scored higher on FOMO tended to feel their basic psychological needs weren’t being met: autonomy (feeling in control of your own life), competence (feeling effective), and relatedness (feeling connected and valued by others).

In other words, FOMO is not primarily a reaction to a specific opportunity you’re missing. It is an expression of needs that are not being met elsewhere.

For traders, this is a critical insight. The urgency to enter that trade, the discomfort of watching charts you’re not in, the compulsive re-checking of Discord or X for what others are playing, these are all attempts to solve a non-financial problem through a financial medium. The trade becomes a proxy for competence, for belonging, for being someone who “got it right.” This urgency intensifies dramatically under evaluation conditions, the psychology of prop firm challenges is where FOMO under pressure does the most damage.

When I describe FOMO to traders in live sessions, I compare it to a rip current. It doesn’t feel dangerous at first, it feels like momentum, like something you should move with. But if you push straight into it, you exhaust yourself and get pulled further off course. The move is to pause. Breathe. Re-center. Reassess before acting on the impulse. Then, if the setup truly meets your criteria, take the trade. If it doesn’t, let it pass. The current will pass whether you act or not.

The trade cannot actually fulfill your needs. Which is why the feeling returns, immediately, after every FOMO entry, win or lose.

The Neuroscience: Why “Missing Out” Feels Like Danger

There’s a useful way to understand why missing out feels so uncomfortable.

When you expect a reward and it doesn’t come, the brain registers the gap, and that feels bad. When a trader watches a position run without them, it can feel like a reward was right there and got taken away. The discomfort pushes you to do something about it.

The brain is not processing “I missed a trade.” It is processing “a predicted reward did not materialize.” The corrective action it signals is: get into the position. Now. Even at a worse entry.

The amygdala compounds this. Brain-imaging studies on herding suggest that the pull to follow the crowd involves the part of you that reacts before you can think. The evolutionary basis is not subtle: for early humans, social exclusion, being left out while the group feasts, celebrates, or profits, was a genuine survival threat.

The amygdala does not know it is 2026. When a Discord group is posting screenshots of triple-digit gains on a position you’re not in, the amygdala registers a social threat. It doesn’t label it “FOMO.” It labels it “danger.” And it pressures you to act accordingly.

Professional traders don’t eliminate this signal. They develop a different relationship to it. Here’s what one study of real traders suggests about that.

What One Study of Real Traders Found

In 2017, Italian researchers scanned the brains of 20 male traders while they traded the Italian stock market on their own platforms. The traders who completed more trades successfully showed more activity in the planning and control parts of the brain. The researchers also suggested that traders who lean heavily on quick rules of thumb may save effort but make less careful decisions.

It was a small study, and it doesn’t tell us how traders change over years. But it fits what I see: the traders who handle FOMO well have done their thinking before the market opens, so they aren’t making it up under pressure.

This is close to what I teach as Power-based trading. The experienced trader doesn’t experience less FOMO. They have built a process that responds to the signal without being driven by it.

You cannot shortcut this development. But you can understand what you are building toward, and practice deliberately in that direction, rather than through accumulated impulsive repetition.

When FOMO Becomes Its Own Contra-Indicator

Here is something that surprises people about FOMO: when lots of traders feel it at once, the move may be closer to its end than its beginning.

November 2021. Crypto sentiment gauges were deep in “extreme greed” territory. On November 10, Bitcoin peaked near $69,000. Over the following year it lost roughly three quarters of its value.

American Association of Individual Investors (AAII) sentiment data reflects a similar pattern over time: periods of extreme bullishness have often been followed by weaker returns for the S&P 500, though not every time. When optimism becomes crowded, the opportunity set tends to compress.

There’s a simple reason this can happen: FOMO-driven buying often comes in after a move is already extended. As buying becomes saturated, the pool of marginal buyers shrinks. In that environment, late entrants often provide liquidity for earlier participants who are beginning to reduce risk.

Research from JPMorgan Chase Institute (2024) reinforces this behavior: retail investors tend to allocate capital following periods of strong performance rather than ahead of them. In the post-pandemic period, the gap between inflows during high-return environments and lower-return environments has widened, suggesting an acceleration in return-chasing behavior, likely amplified by digital platforms and social media.

Within that data, younger investors, particularly men under 40, show a higher tendency toward reactive allocation, while older, higher-income investors tend to exhibit more stability, more often adding on pullbacks rather than chasing strength.

The Market Is a River, Not a Bus

One of the most practical frames I’ve given traders over the years comes from a simple observation: most traders relate to the market as if it’s a bus. If you miss the 9 AM bus, the next one isn’t for an hour. Missing it costs you something real and specific.

But the market is a river. Another wave comes. And then another. The river doesn’t stop.

The mantra I give traders who are working on FOMO is simple: “The market will always give me another opportunity.” Always. Not sometimes. Not probably. Always. There will be another setup tomorrow. There will be another setup next week. There has never been a point in the history of financial markets where opportunity disappeared permanently. Trading from that belief, not as a hope but as a genuine conviction, changes your relationship to missed trades entirely.

Yosef Bonaparte at the University of Colorado built a FOMO index from Google searches covering 2004 to 2024. Months with high FOMO tended to be followed by lower stock market returns. The FOMO entry is usually a late entry. It is chasing a move that others have already had.

Meanwhile, research by Brad Barber and Terrance Odean found that individual investors pile into attention-grabbing stocks, the ones in the news or making big moves, and those purchases have tended to do poorly afterward. The very things that trigger FOMO tend to show up late in a move.

When you feel FOMO, the most useful reframe is not “I need to get in.” It is: “What is this feeling telling me about where we are in this move?”

From FOMO to JOMO: The Actual Goal

JOMO, the Joy of Missing Out, sounds like a clever inversion. To me it describes the state I see in the most settled traders.

JOMO is not indifference. It is not forcing yourself not to care. It is the genuine satisfaction of executing correctly, which includes the correct decision to not trade.

When a setup forms that does not meet your criteria and you choose not to enter, you have not “missed” anything. You have made a high-quality decision under uncertainty using your established framework. The fact that the trade subsequently ran 8% is a forward outcome that was not knowable at the moment of decision. You made the right call with the information available. That is the work.

The Przybylski research explains why this is so psychologically difficult early in a trader’s development: if your sense of competence is tied to being “in the move,” then not trading feels like incompetence. But if your sense of competence is tied to executing your process correctly, then not trading when the process says no is the competent action.

This transition, from outcome-referenced self-worth to process-referenced self-worth, is the central psychological work of developing as a trader. It is also the transition from Force to Power. Force trades out of fear of missing. Power operates from the quiet conviction of a tested process.
