They measured the investment facility of all those LLMs. That's pretty much what the title says. And they had dramatically different outcomes. So that tells me something.

They "proved" that US tech stocks did better than portfolios with less US tech stocks over a recent, very short time range. 1. You didn't know that? 2. Whata re you going to do with this "new information"?

It shows nothing. This is a bullshit stunt that should be obvious to anyone who has placed a few trades.

I mean, what it kinda tells me is that people talk about tech stocks the most, so that's what was most prevalent in the training data, so that's what most of the LLMs said to invest in. That's the kind of strategy that works until it really doesn't.
