Using a large data set with 80,214 repeat sales, we find that the real return on a diversified portfolio of modern prints sold at auctions worldwide averaged a modest 1.51% during the period 1977–2004. We address several issues regarding the performance of modern prints as investments: the selection bias arising from the self‐interest of auction houses; the impact of an ever‐expanding universe of auction houses on investment returns; the “masterpiece” effect, or whether more expensive works of art outperform the market as a whole; and the differences in returns that arise due to random fluctuations in collector tastes.
