What is FOMO?
Fear of missing out — the urge to buy because prices are rising and everyone else seems to be getting rich. Historically the retail investor's most expensive emotion.
FOMO — fear of missing out — is the urge to buy because the price is rising and everyone around you seems to be getting rich. It is not a market condition; it's an emotion, and in retail investing it has a consistent record: FOMO peaks precisely when prices do, which is how the crowd reliably arrives at the top.
The mechanism is worth respecting because it's built into markets: rising prices generate stories, stories generate buyers, buyers generate rising prices — until the supply of new believers runs out. The defences are structural, not willpower: a schedule that buys mechanically, position sizes decided in advance, and a habit of checking the sentiment index before acting — if greed reads 80+, the urge you're feeling is the crowd's, on loan.

FAQ
How do I know if I'm FOMO-buying?
The tells: the urgency arrived from a price chart or someone else's gains, not new analysis; waiting a day feels unbearable; and you're increasing the size "because it's running". A decision that can't survive a 24-hour delay usually isn't one.
But what if I really do miss out?
You will — everyone misses most winners, and the portfolio damage from FOMO entries has historically outweighed the missed upside. Scheduled buying converts "missing out" into "participating on your terms".
