Nvidia’s latest 13-F also indicates it sold its stake in Serve Robotics, and shares of the self-driving-technology company are also sliding.

Shares of AI-driven voice recognition expert SoundHound AI (NASDAQ:SOUN) were crushed after Nvidia (NASDAQ:NVDA) revealed it had completely dumped its stock. It was hardly the love note investors were expecting to receive on Valentine's Day.

Most AI stocks have continuously been rising with greater momentum, so it’s not a smart idea to completely disregard any AI stock in the current environment. So, SOUN stock is a buy if you are going to put this stock along with some speculative high-risk, high-reward bets.
