Down 40% This Year, Is CarMax Stock A Buy?
CarMax (NYSE:KMX) stock has declined by 23% over the last five trading days, falling to levels of about $44 per share. The stock also remains down by over 40% year-to-date. At these levels, the stock looks somewhat inexpensive, trading at just about 13x trailing earnings and 0.3x sales, well below the S&P 500. Moreover, KMX remains a solid business, with a large national store network and a growing digital footprint giving it network effects that smaller competitors just can’t match. The key question is whether the stock is cheap enough to be a buy. The answer, however, is not very convincing.
But no matter how attractive, investing in a single stock carries high risk. The Trefis High Quality Portfolio is designed to reduce stock-specific risk while giving upside exposure.

The sharp sell-off follows a weaker-than-expected set of Q2 FY’26 results (Feb. fiscal year), as well as relatively cautious commentary from management on demand outlook. Revenues over the last quarter declined 6% year-over-year to $6.59 billion, while earnings fell to $0.64 per share, down from $0.85 a year ago. The company’s financing arm is also coming under some pressure, with income down 11% to $103 million, while provisions for loan losses jumped to $142 million from $113 million last year. On the retail front, comparable store used-vehicle sales dropped 6% year-over-year, hurt by cautious consumer spending as well as elevated borrowing costs, which have impacted the broader used vehicle market. Moreover, a pull-ahead in sales earlier this year – likely driven by tariff-related fear-buying also likely compounded the slowdown over the quarter.
