> Grok ended up performing the best while DeepSeek came close to second. Almost all the models had a tech-heavy portfolio which led them to do well. Gemini ended up in last place since it was the only one that had a large portfolio of non-tech stocks.
I'm not an investor or researcher, but this triggers my spidey sense... it seems to imply they aren't measuring what they think they are.

Also studying for eight months is not useful. Loads of traders do this well for eight months and then do shit for the next five years. And tellingly, they didn't beat the S&P 500. They invested in something else that beat the S&P 500. And the one that didn't invest in that something did worse than the S&P 500.
What this tells me is they were lucky to have picked something that would beat the market for now.
