[The scale of artificial intelligence trading is astonishing, Castle Securities said it has reached the point where there is “no room for error”] On October 27, Castle Securities believes that the market has invested so much in artificial intelligence trading that there is almost no room for error once the huge investment fails to generate returns. Nohshad Shah, the company's head of fixed income sales for Europe, the Middle East and Africa, wrote in a research note that the sell-off in technology stocks shows that investors are becoming increasingly demanding on whether huge spending on artificial intelligence will ultimately generate enough profits. “With so much of the economy and stock markets now betting on AI trading, and other risks potentially emerging, the market has little room for error,” Shah wrote.
