Tokyo, June 25 (Jiji Press)--Japan's bellwether Nikkei 225 stock average briefly shot up over 2,000 points Thursday morning, as issues linked to artificial intelligence and semiconductors gathered hefty buying. At 10:02 a.m., the index of 225 major issues on the Tokyo Stock Exchange's top-tier Prime section stood 2,044.03 points, or 2.95 pct, higher from Wednesday at 71,219.00. Investors were heartened by a jump in the stock price of U.S. memory chip maker Micron Technology in off-hours trading, after the company reported a brighter-than-expected earnings forecast for June-August on Wednesday. Micron Technology's industry rival, Kioxia Holdings, especially attracted buying on the Prime section. END [Copyright The Jiji Press, Ltd.]
