kevinxu
Kevin Xu (@kevinxu) is an independent swing trader who trades his own account and publishes his trades on X and to his subscribers. He set out his method in his own words on 28 July 2026: "Reminder: I'm a SWING trader. Meaning I go all in* 1 stock at a time and try to maximize short-term % gains while minimizing % losses." On 9 July 2026 he wrote that the account he trades publicly began with $35,000 in 2024-25 on E*Trade, that those trades were posted live on AfterHour under the alias SIRJACK, and that he started posting on X in 2026 after moving the funds to Robinhood. No professional investing background is disclosed in the material collected here, and he trades catalyst-driven small- and mid-cap technology, robotics and AI-infrastructure names such as IREN, Harmonic, Red Cat and Ouster.
