DeepSeek made 19 trades on July 14, adding to Nvidia and cutting Vista Energy in the latest moves from the AI-run portfolio tracked by University of Florida professor Alejandro Lopez Lira.
35% year to date, DeepSeek is outperforming ChatGPT at 16% and Grok at 19%, which Lopez Lira said makes it the strongest current trader among the models he has tested since 2023.
73% since launch in 2023, DeepSeek still trails ChatGPT's 78% cumulative return, while Lopez Lira said the models reach the same stock calls only about 50% of the time after being fed news and fundamentals.
Autopilot, the copy-trading app hosting the portfolios, has seen rising interest in AI-managed strategies as users increasingly try to mirror model-driven stock picks.
