I don’t understand this constant fascination with having language models trade stocks. Language models are very useful tools but not aligned at all with generating alpha.

The usual question: what's "aligned with generating alpha" that a human stock trader can do, but an ai can't?

I don’t understand these arguments. You have to realize anything an LLM does has been exploited for decades by well funded shops.

I don’t understand why anybody would use LLM:s for trading (other than some narrow speed trading news)

even in that case I would have an LLM analyzing the news trigger a deterministic API call. I can't imagine the use case for this besides vibe-trading

Totally.

Yes but there’s many reports of agents getting back testing to work but it never translates to real trading. It seems they tend to overfit to back testing so I’m just giving them access to Twitter sentiment, other trading data thru tools and not necessarily an algo that’s been back tested. It’s why the flash models are doing better image they have faster tps and can call the tools faster.

>they have faster tps and can call the tools faster. This is like going to war with the HFT firms armed only with a stalk of celery ("it's much pointier than the tomatoes, even though those are more expensive").

Flash vs non-flash models are more about letting me know if model intelligence or model speed (with powerful tools/MCPs) are better for trading. I’m not telling the model to be fast as possible because HFT firms are already arbitraging those mini seconds to make pennies.

Alas, many financial models do well in backtests and then fail in the real world. You have to expose them to all kinds of market conditions and not just the recent one. Good luck out there!

Yes even before AI, backtesting was a crapshoot. But AI adds another crease because it might have knowledge in its training. If you’re training an LLM model on backtesting, it might know that Apple crushed a certain quarter and knowing that, it buys shares before that Q earnings.

The only way to win is to not play. https://www.bogleheads.org/wiki/Getting_started

Bogleheads are still playing.

Bogleheads is maximizing potential economic gains from investing in the capital market while minimizing costs from the exposure attempt.

The results from dollar cost averaging into VT or a target date fund for the next 30-50 years is likely superior to gambling on single named securities or options, for the unsophisticated.

Right. But you're still putting your money at risk seeking reward - aka playing the game.

Outside of FDIC insured cash accounts, the most anti-gambling way to play would be to buy nothing but TIPS. But even those have a (small) risk.

So one of the ways Robinhood makes money is payment for order flow (PFOF).

One lens to view PFOF is that it connects the most sophisticated traders (HFTs, etc.) with the least sophisticated traders (retail).

Inventing a new, even less sophisticated class of traders seems like exactly the kind of thing that makes sense for their business model.
