与人工智能相关的科技股下跌，导致华尔街连续第四天下跌，受获利了结和估值担忧。 AI-related tech stocks fell, driving Wall Street’s fourth straight day of losses amid profit-taking and valuation concerns.

主要技术库存,尤其是那些与人工智能有关的库存,星期三再次下降,助长了华尔街的滑坡,并将市场推向连续第四天的损失。 Major technology stocks, particularly those tied to artificial intelligence, declined again on Wednesday, contributing to Wall Street's slide and pushing the market toward a fourth consecutive day of losses. 经济下滑的驱动力是投资者对估值和盈利的担忧,因为投资者在年初经历了强劲的运行之后对估值和利润的获取感到担忧。 The downturn was driven by investor concerns over valuations and profit-taking after a strong run earlier in the year.
