FOMO (Fear of Missing Out)

Fear of Missing Out (FOMO) in investing is the anxiety that other people are making money on an asset that you are not invested in, leading to impulsive buying — usually near the top of a price move. It is among the most expensive behavioural biases for retail investors.

How FOMO presents:

• Chasing a stock or fund after a 50-100% rally because "everyone is in it".
• Buying small-caps or thematic funds on the strength of recent past returns.
• Allocating to speculative themes (crypto, IPO frenzies, "story stocks") at peak coverage.
• Concentrated bets that violate your asset allocation discipline.

Example: A small-cap fund returned 50% in CY24 and was prominently covered on social media. An investor abandoned her balanced 60/40 plan and put 40% of her portfolio into the fund in early CY25 after seeing peers' returns. The small-cap segment then corrected 25-30% mid-year — her portfolio drawdown was meaningfully worse than her risk profile could tolerate, and she sold in panic, locking in losses.

Why FOMO is dangerous:

• Past returns mean-revert: high recent returns tend to be followed by lower forward returns.
• Position-sizing breaks under FOMO — investors put in amounts they cannot psychologically hold through a 30% drawdown.
• It is often paired with recency bias and herd behaviour.

Counter-measures:

• Write an Investment Policy Statement (IPS) defining asset allocation; review only twice a year.
• Pre-commit using SIPs — automates buying across cycles.
• Use a "24-hour rule" for any new investment idea — no acting on the same day.
• Track rolling-return ranges (not point-to-point); they show the volatility of the asset class and reset expectations.
