“The great investors bought vast quantities of art,” the firm writes.19 “A subset of the collections turned out to be great investments, and they were held for a sufficiently long period of time to allow the portfolio return to converge upon the return of the best elements in the portfolio. That’s all that happens.” The great art dealers operated like index funds. They bought everything they could. And they bought it in portfolios, not individual pieces they happened to like. Then they sat and waited for a few winners to emerge.
