CarMax heads into its June 17 earnings print as one of the most dramatic short-squeeze setups in automotive retail this year.
The stock's 41% rally over the past month — bringing shares to $52.21 — has caught short sellers badly offside. Short interest has fallen nearly 12% in a single week, dropping to 10.2% of the free float, as position-holders cover into the move. That pullback in short positioning is notable given where shorts were just two weeks ago: roughly 17 million shares borrowed, versus under 15 million now. Despite the covering, SI remains structurally elevated at over 10% of float. The borrow market itself offers no squeeze pressure — availability is running at an extraordinarily loose 3,645%, meaning there are roughly 36 shares available to borrow for every one currently lent out, and borrowing costs are minimal at 0.44%. Options traders have not turned more defensive into the print; the put/call ratio of 0.77 is slightly below its 20-day average, near neutral and well off the 52-week high of 0.89.
The analyst community paints a sharply divided picture heading into the print. The Street is broadly bearish on the stock at these levels. Barclays and JP Morgan both carry Underweight ratings, and while each raised price targets in the days before the report — Barclays moved from $26 to $31, JPMorgan from $35 to $37 — both targets remain dramatically below the $52.21 current price, implying the two firms see roughly 30-40% downside even after acknowledging some improvement. UBS initiated coverage at Neutral with a $42 target in late May. The consensus mean target of $42.69 is about 18% below where the stock is trading, a meaningful valuation gap. Bears argue that CarMax's 80% revenue exposure to used-vehicle sales leaves it vulnerable to margin compression as average selling prices fall and marketing spend rises. The bull case rests on CarMax being the largest used-vehicle retailer with only 3.6% US market share, meaning volume growth runway remains wide — if price cuts and advertising are driving unit acceleration, the model can still deliver earnings improvement over time.
The earnings history adds context to the stakes. The April 2026 print produced a punishing 17.5% single-day drop and a 20.5% five-day loss — the worst reaction in the dataset. The prior December 2025 print fell 6.3% on the day. The stock has now recovered virtually all of that April damage in six weeks. Starboard Value, a known activist, holds a 4.4% stake per the most recent filing — a signal that at least one large holder sees structural undervaluation.
The June 17 report is therefore less about whether CarMax can sell more cars and more about whether the scale and pace of unit-growth recovery, at these multiples, justifies a stock that has repriced 41% higher while the analyst consensus still points to significant downside.
