Diamond Hill Select Fund stated the following regarding CarMax, Inc. (NYSE:KMX) in its third quarter 2025 investor letter:

“Among our bottom individual Q3 contributors were American International Group (AIG) and CarMax, Inc. (NYSE:KMX). Used car dealer CarMax saw a meaningful slowdown in used retail vehicle sales as well as higher credit-loss provisions in its captive financing arm. We believe consumers likely pulled forward vehicle purchases ahead of tariffs, leading to a recent industry lull. Combined with uncertain consumer sentiment and heightened competition, shares were pressured in the quarter. However, we believe CarMax remains capable of taking share in a fragmented market over the longer term and are confident in the management team, which is focused on finding efficiencies to enable it to spend more on consumer-facing initiatives.”
