Director Mahan Oscar Leland purchased 712 shares of John Marshall Bancorp at $18.63 on 2025-07-15, adding to a 92.9K-share position. The timing follows a sharp 90-day rebound of +33.4% from prior lows, occurring when the stock is -25.9% from its 52-week high. Critically, his cross-ticker track record shows 1 prior buy with an average 90-day return of -19.0% and a 0% win rate, suggesting his buy decisions have historically underperformed.

At JMSB specifically, his 5 prior trades in 2024 were all sells, each well-timed with negative 90-day returns ranging from -17.8% to -18.2%, yet this purchase represents his first buy at this ticker, contrasting sharply with his established pattern of selling here.
