Director Mark F Oneil purchases 9,600 shares of KMX for $502,656.00 across 2 trades at $52.36

Mark F Oneil, Director at CarMax, executed 2 purchases totaling 9,600 shares for $502,656.00 at $52.36 on 2026-06-24. His post-transaction holding stands at 4,800 shares. At his prior KMX buy on 2025-10-02, the stock returned -9.3% over 30 days and -16.4% over 90 days, establishing a pattern of subsequent price weakness following his purchases at this ticker. The current price of $52.76 is -26.7% from the 52-week high of $71.99 and +24.8% over the past 30 days, showing recent recovery from depressed levels. The company's P/E of 33.61 against -1.8% annual revenue growth presents a valuation context that differs materially from fundamental momentum.

Director ONeil purchases 10,816 shares of KMX at $46.21; holdings increase 78.0% to 24,690 shares as stock trades -47.5% from 52-week high

Mark F. ONeil, a director of CarMax, purchased 10,816 shares at $46.21 on 2025-10-02, expanding his position from 13,874 shares to 24,690 shares—a 78.0% increase in holdings. This purchase occurs as KMX trades at $46.81, down 47.5% from its 52-week high of $89.19 and down 31.5% over the past 90 days, representing a significant period of price weakness. The company's fundamentals remain moderate with a P/E of 13.19 and annual revenue growth of -0.7%, though net income of $95,378,000.00 on quarterly revenue of $6,594,684,000.00 is positive. The substantial increase in holdings during a prolonged downturn is factual evidence of insider accumulation, though the stock's current valuation relative to historical levels and future trajectory remain questions for investors to assess independently.
