Nikkei 225 ends 0.6 percent lower as AI worries persist

Why did the Nikkei 225 fall on October 19?

Semiconductor and other technology stocks remained under pressure as investors questioned whether heavy artificial intelligence spending will produce sufficient returns. Reuters said the index had fallen more than 2 percent earlier before recovering part of the loss.

Banking, utilities and other domestic sectors helped limit the decline. The broader market finished almost unchanged, while the Nikkei remained exposed to the technology selloff, News On Japan reported.
