About this episode

The episode explores whether AI is making stock markets more efficient or just more reactive.

Investors are currently obsessed with AI’s potential in almost every sector, but for investors, the stakes are uniquely high. Is this technology going to turn the stock market into a perfectly efficient machine where “alpha” goes to die, or is it actually creating more chaos for the rest of us, the stock pickers, to exploit? In my latest video, I dive into this tension. Inspired by a recent Goldman Sachs podcast featuring their quant team, I explore the widening gap between how machines “price” assets and how long-term value is actually built. The big question I want to pose to you: Is AI making markets more efficient, or is it just making them more reactive? I’ve shared my full thoughts in the video, but I’d love to hear your take in the comments – are you finding AI to be a net positive for your strategy, or is it just adding noise?
