View all 560 holding institutions

Across its top 20 institutional holders, KMX's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 9/100, avg. turnover score 36/100).

Notable Holders

KMX ranks #1039 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

KMX is a disclosed holding of Cliff Asness (AQR Capital Management), one of the tracked superinvestors on AlphaSMO — it makes up 0.1% of that fund's own 13F portfolio.

KMX is a top-conviction position for Rings Capital Management LLC — at 25.5% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in KMX belongs to BlackRock, Inc., but the position matters far more to Rings Capital Management LLC, who has 25.5% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

BlackRock has added to its KMX position for two straight quarters, increasing it by $214.3M to reach $904.0M today.

Apollo Management Holdings, L.P. has trimmed its KMX position for two straight quarters, cutting it by $89.9M while still holding $105.1M.

KMX is down 1.3% today, but institutions show net buying of $326.1M this quarter — a divergence between today's price move and the underlying institutional flow.

KMX posted net income of $222.5M over the trailing twelve months, and currently trades at a P/E of 40.7.

Smart Money Convergence

KMX does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

CarMax (KMX) disclosed in an 8-K that Diane Cafritz, its Executive Vice President and Chief Innovation and People Officer, will leave the company on December 31, 2026. Under her existing severance agreement she would have been eligible for 1.5x (base salary plus target bonus), but an amendment removes the target-bonus component and instead gives her her actual full-year bonus for fiscal 2027. She will also stay on as a consultant from January 1 to June 30, 2027, for $360,500 total (half her current annual base salary), and her non-solicitation and non-compete covenants will be extended by six months, expiring two and a half years after her departure.
