AI may be dominating headlines right now—but headlines don’t always tell you where the real opportunities are. The strongest signals aren’t just coming from mega-caps. They’re bubbling up across industries, from semiconductors to heart surgery devices to online grocery platforms.

📈 Top AI Scorers of the Week 

These stocks had the highest AltIndex scores this week—based on Reddit buzz, hiring trends, web traffic, and more.

If our AI model was an AI agent like OpenAI’s new product, it would probably try to sell these holdings for you while you weren’t looking. And you might thank it later.

Kirklands and ContextLogic have been haunting the bottom five for a while—we’ll be watching with baited breath to see if they can pull themselves up by the bootstraps or not.
