“Everyone (including LLMs) is a genius in a bull market.”

I was thinking the same thing. A number of coworkers where trading stocks a few years ago and felt pretty good about their skills, until someone pointed out that making good stock picks was easy when everything is going up. Sure enough, when the market started to fail, they all lost money.

What could make this a bit more interesting is to tell the LLM to avoid the tech stocks, at least the largest ones. Then give it actual money, because your trades will affect the market.

Apparently everyone (but Gemini).
