TOKYO - The Nikkei stock index surged over 3 percent Thursday morning, boosted by technology shares after U.S. tech giant Micron Technology Inc. reported robust earnings and a drop in crude oil futures.

At 10:50 a.m., the 225-issue Nikkei Stock Average rose 2,461.03 points, or 3.56 percent, from Wednesday to 71,636.00. The broader Topix index was up 51.60 points, or 1.30 percent, at 4,015.36.

The Nikkei stock index climbed, recovering to the 71,000 level, as concern over a fall in demand for memory chips used in artificial intelligence data centers faded.

The Nikkei lost over 3,100 points in the two trading days through Wednesday.

The overnight decline of the benchmark West Texas Intermediate crude oil futures contract below $70 per barrel also lifted the market.
