The U.S. dollar was trading at 163.17 yen as the Japanese currency wavered near its lowest level in 40 years. Expectations that the gap between U.S. interest rates and Japanese interest rates will widen due to higher inflation in the U.S. have helped to drive the dollar higher against the yen.

The Nasdaq composite fell 0.6% to close at 25,690.90 as Alphabet Inc., parent company of Google, sank 1.5% ahead of its earnings report, which arrived after trading ended.

However, its share price fell another 2.9% in after-hours trading.

Investors are looking for signs that the deluge of dollars going into processors, computer memory and other building blocks of the AI boom will yield enough profits to make the investments worthwhile. Such worries have kept AI stocks at the center of Wall Street’s swings for weeks.

Micron Technology swung between a loss of 3.6% and a gain of 1.2% before finishing with a drop of 1.2%. It had jumped 14.4% in the first two days of this week to reclaim nearly all its 13.3% plunge from the week before. It’s still up 236% for the year so far.

Early Thursday, the price for a barrel of Brent crude oil, the international standard, was up 3.8% at $97.61, its highest level since early June.

U.S. benchmark crude gained 3% to $89.39 a barrel.
