CarMax (KMX) Jumps On BofA Upgrade As Valuation Debate Stays Open

Listen to the news

CarMax (KMX) drew fresh attention after its shares climbed 4% following an upgrade from BofA Securities. The firm pointed to tougher price transparency rules that may favor the used car retailer.

CarMax’s share price has climbed 33.93% year to date, even after a 12.09% decline over the past 30 days and an 8.22% drop across 90 days, with the recent 1-day share price return of 5.62% hinting at momentum returning as investors react to analyst upgrades and earnings optimism. Over a longer horizon the picture is mixed, with 1-year total shareholder return of 21.61% contrasting with declines of 17.03% and 62.92% over the past 3 and 5 years, which keeps current enthusiasm anchored by a history of weaker long term outcomes.

CarMax now trades with fresh analyst support and a sharp short term rebound, set against a longer record of mixed shareholder outcomes. Does that recent enthusiasm still leave more upside than downside on the current valuation?

Most Popular Narrative: 2.7% Undervalued

CarMax closed at $52.62 against a widely followed fair value narrative of $54.09, a small gap that still leans to the upside and rests on management’s own words about pricing, margins, and efficiency trade offs.

The pledge returns only when analysts ask for it, and it returns with a date and a qualifier. Mayor-Mora: “certainly for FY 2028, that is the intent, right?” Asked why GPU should not be cut harder, he says “we do not necessarily need to go down that route as the first selection, if you will.” The earlier construction was “rather than lowering GPU.” This one may read as ranking lower GPU second instead of excluding it. Moderate confidence.

See why 1 investors see CarMax as 3% undervalued.

Result: Fair Value of $54.09 (UNDERVALUED)

Still, CarMax’s reliance on FTC enforcement tailwinds and a softer pledge around self funding price cuts could both unsettle that modest undervaluation story.

Another View: CarMax Looks Expensive On Earnings

That small 2.7% gap between CarMax’s $52.62 share price and the $54.09 fair value story meets a very different message from earnings multiples. The stock trades on a P/E of 25.5x, while the US Specialty Retail industry sits at 16.9x and close peers at 11.9x.

Even against an estimated fair ratio of 21.1x, CarMax screens as rich, which suggests less room for error if the optimism behind the narrative weakens.
