AI Trading Bots Struggle to Beat the Market

Este título foi resumido pela IA a partir da publicação abaixo.

(Yup....) AI Bots Auditioning for Wall Street Trading Are Mostly Losing Across a series of new trading contests between the world’s leading AI models, the verdict so far is unflattering. Most of the systems lose money. They trade too much. They make wildly different decisions when given identical instructions. And no one yet knows if these shortcomings will fade with more powerful iterations — or if they reveal something fundamental about the gap between large language models and how markets actually work. The portfolio as a whole lost about a third of its capital. Across all 32 sets of results, a model finished in profit only six times. Grok 4.20 delivered the best performance during the challenge in which it was aware of its rivals’ performance. It placed only 158 trades; under the same prompt, Alibaba’s Qwen traded 1,418 times. “Human in the loop” remains the motto when it comes to trading real money. Perhaps for good reason. They tend to mistime their trades, incorrectly size positions and buy and sell too often. That outcome mirrors human performance, since a majority of actively managed funds famously also lag the broad market. And just like people, the models can be prone to obvious bias. The default test for a trading strategy — running it backward through history to see how it would have performed — doesn’t really work for AI. “Giving an LLM money right now and just having it go — that’s not a thing yet,” said Azhang. "When LLM agent trading strategies start working, you will not hear about it for a while.” https://lnkd.in/ez4ddwdK
