alt Hacker NewsJust one run per model? That isn't backtesting. I mean technically it is, but "testing" implies producing meaningful measures.
Also just one time interval? Something as trivial as "buy AI" could do well in one interval, and given models are going to be pumped about AI, ...
100 independent runs on each model over 10 very different market behavior time intervals would producing meaningful results. Like actually credible, meaningful means and standard deviations.
This experiment, as is, is a very expensive unbalanced uncharacterizable random number generator.

To their credit, they say in the article that the results aren't statistically significant. It would be better if that disclaimer was more prominently displayed though.
The tone of the article is focused on the results when it should be "we know the results are garbage noise, but here is an interesting idea".
To take it to the absurdist conclusion, you could backtest each LLM "which single stock should I buy on Jan 1, 2010 to maximize my returns over the next 15 years?"
If your backtested LLM performed well, would you use the same strategy for the next 15 years? (I suppose there are people who would.)
Yeah...one run per model is just random walk in my opinion
Yes, if these models available for $200/month a making 50% returns reliably, why isn’t Citadel having layoffs?
Yes definitely we were using our own budget and out of our own pocket and these model runs were getting expensive. Claude costed us around 200-300 dollars a 8 month run for example. We want to scale it and get more statistically significant results but wanted to share something in the interim.
