The Bull

The feeling of certainty and the actual quality of an investment decision are two entirely different things that your brain stubbornly insists on treating as one and the same. Confidence is an emotion manufactured inside you; edge is information the wider market doesn't already have and hasn't already priced in. Buying the thing that's already mooning feels exactly like conviction — but by the time something has run far enough to feel like an obvious, can't-miss winner, its recent run is genuinely the least secret fact about it. Everyone else is staring at the identical chart you are.

What's actually doing the steering here is recency bias: the mind quietly over-weights whatever just happened and, almost without asking permission, assumes it will simply keep happening. So a hot streak reads as a durable trend you can comfortably ride rather than a price that has already done most of its moving, and "it's been going up lately" becomes, without you ever consciously deciding it, "it will obviously keep going up." That's the real machinery underneath chasing — it isn't greed, exactly, just a very normal brain placing far too much trust in the most recent data point it happened to be handed.

The genuinely costly part is that chasing tends to quietly invert good timing. Excitement reliably peaks after the big run, which is to say near the top, and dread reliably peaks after the sharp drop, which is to say near the bottom — so the emotional cycle keeps nudging you to buy high and sell low, the precise reverse of the plan you'd write down in a calm moment. Each individual move feels responsive, alert, and smart in the instant you make it; stacked up across years, they quietly drain a real slice of what patient money left alone in the very same holdings would have made.

That drain isn't hypothetical or moralizing — it's measurable, and it's the strongest argument going against trusting the excitement. Large studies of how investors actually behave find the average dollar trails the very funds it's invested in by more than a full point a year, and not because the underlying picks were bad — because the buying and the selling were mistimed. Worse, the more people traded in and out, the wider that gap reliably grew. The frantic activity that feels like staying on top of your money is often the exact thing quietly working against your result.

None of this is an argument to sit the market out — actually being in it is a genuine strength, and that healthy appetite for risk is well worth keeping hold of. It's an argument for cleanly separating the fun from the foundation. Keep a small, deliberately capped sleeve where conviction gets to play and the stakes stay firmly contained, and let the boring majority quietly ride a plain, automatic index fund (a low-cost basket of the whole market) that no group chat gets to steer. And write your thesis down before you buy, so that later you can honestly tell a real skill apart from a lucky guess.
