“I’m diversified” is one of the most comforting sentences in investing, and one of the least examined. Owning twelve things isn’t a strategy — it’s often just twelve unexamined opinions wearing a portfolio’s clothing.
Diversification without conviction is just noise reduction
Spreading capital across many positions dampens volatility. It does not, by itself, improve your odds of being right about any one of them. If you can’t articulate a one-sentence thesis for a position — why it wins, what has to be true, what would prove you wrong — you don’t have conviction in it. You have exposure to it. Those are different things, and only one of them compounds.
The confession diversification often hides
Over-diversification frequently means: “I don’t trust my own analysis enough to size any single position meaningfully.” That’s a legitimate position to be in — but it’s worth naming honestly, because the fix isn’t more positions, it’s more analysis. A portfolio of forty small bets you can’t defend individually isn’t safer than eight you can; it’s just harder to be embarrassed by any single one.
A better test than position count
For every holding, write the thesis in one sentence and the invalidation condition in another. If you can’t fill in the second sentence, you don’t actually know what would make you sell — which means you’re not managing the position, you’re just watching it. That’s the real risk diversification is supposed to protect against, and spreading capital thinner doesn’t fix it.
