CFO Jeffrey S. bought 2,000 shares of SI at $15.00; company unprofitable but shows +49.6% revenue growth and cluster buy pattern
Jeffrey S., Chief Financial Officer of Shoulder Innovations, purchased 2,000 shares at $15.00 on 2026-03-13, bringing his holdings to 70,785 shares. The company reported a net loss of $-8.7M on revenue of $11.8M in its latest quarter, though full-year revenue grew 49.6% year-over-year. Notably, 2 other insiders also bought within the past 14 days, creating a cluster purchase pattern. However, Jeffrey's own prior purchase history at SI is concerning: his 4 previous buys at this ticker generated no gains at the 90-day mark (0 of 4 were profitable), with individual 90-day returns ranging from -2.4% to -20.7%. The company's unprofitable status and his track record of unsuccessful timing at this ticker warrant careful review of whether this purchase reflects conviction or other factors.
