Why you bought at the top, and what your brain was actually doing.

Almost every first-year investor has a version of this story. A stock keeps climbing for weeks. Friends mention it. Group chats reference it. Twitter, TikTok, Reddit are all loud about it. Eventually, it feels like the only people not in the trade are the ones who don’t get it.

So you buy. Often near the top. Then it falls. And the part that hurts most is not the dollar amount. It is the realisation that, at the moment of the decision, the action felt completely rational.

The behavioural finance literature has a name for what happened. Several names, in fact. Recency bias makes the recent past feel like the future. Herding makes consensus feel like signal. FOMO makes inaction feel like loss. None of these are character flaws. They are baseline features of how human attention works under uncertainty.

Knowing this does not make you immune. It makes you slightly slower. And slightly slower is most of what good investing actually is.

At StarryTrader, every Stock Story includes a sentiment summary, a price-cycle context, and a plain-language explanation of what changed. The point is not to tell you what to do. The point is to make the conditions under which you make the decision a little less hostile to your own judgement.

Next time the group chat is loud, try this. Do not act on the first impulse. Read the cycle visual. Ask whether the news is actually new, or whether the price moved first and the explanation arrived later. Most of the time, the explanation arrived later.
