A young investor learns to diversify. An experienced one learns to concentrate. The third move — and the one that distinguishes the careers we admire — is to know when each is the right answer.
Diversification is the right default. Most investors should hold more positions than they want to. Most institutional capital should be diversified across managers, geographies, and vintages. Most retail capital should be in low-cost index funds. None of that is in dispute.
But for an investor designed to own, diversification past a certain point is a form of indifference dressed as prudence. A portfolio of one hundred businesses cannot be a portfolio of one hundred convictions. It can only be a portfolio of one hundred bets — and the difference between those two postures is where compounding lives.
What concentration is, and is not
Concentration, as we practice it, is not the absence of risk discipline. It is risk discipline expressed differently — through the depth of work done before a position is taken, the standards a position must clear to be sized, and the temperament required to hold it through the periods when it is unfashionable.
At Kopyan Holding, the average portfolio position size is materially larger than what the industry would consider conventional. We are willing to size up because we are unwilling to widen our circle. The price of a concentrated portfolio is a small one — and the discipline of staying inside it is hard.
A portfolio of one hundred convictions is not a portfolio. It is a list.
The temperament cost
The hardest year of a concentrated portfolio is rarely the year you buy. It is the year, three or five years in, when the thesis is taking longer than expected and the market is busy with other things. The right answer in that year is almost always to do nothing — but doing nothing is the most expensive action available to an investor who has been told, all his career, that he is paid to act.
We try to design our work to make the right answer easier. We document theses in writing on day one. We re-read them on a schedule. We refuse to evaluate portfolio positions on a horizon shorter than the one we underwrote. We compensate the team for the compounded outcome of investments owned — not for activity, transactions, or interim marks.
When we would diversify
We would diversify — and have — in three circumstances.
The first is when we do not know enough to concentrate. A new sector, a new geography, an unfamiliar asset class — these are not concentration territory until they are conviction territory, and that takes years.
The second is when the cost of being wrong is structurally asymmetric. There are positions in any portfolio where the magnitude of a bad outcome is large enough that the discipline of concentration becomes a vanity. We size those positions accordingly, or pass.
The third is when our capital base requires it. Permanent equity tolerates concentration. Capital that has a duration, or a redemption window, deserves a different shape.
None of this is a defense of recklessness. Concentration without preparation is a wager. Concentration with preparation is, in our experience, the only durable source of above-average outcomes for investors with the temperament to hold it.
It is also, not coincidentally, the only structure of investment that puts the investor and the operator on the same side of the table — both with most of what they own depending on most of what they do.
