That's a bit curious. I was supposing that all the hedge funds should have incorporated LLMs in their models by now, since it should give them such a huge advantage. Is it not so?

I don't think there is a basis for this reasoning

LLMs don't know what's right automagically, a model fine tuned by a hedge fund is definitely better than just an LLM's hallucinating something

Of course I mean LLMs fine-tuned by the hedge funds, not something off-the-shelf. My reasoning is that sentiment analysis and similar techniques have been used for a while, and LLMs raise them to the next level, so they are bound to be beneficial.
