Tokyo, July 17 (Jiji Press)--Japan's benchmark Nikkei 225 stock average briefly plunged over 2,700 points Friday morning due to selling of issues related to semiconductors and artificial intelligence following overnight falls in their U.S. counterparts. At 9:43 a.m., the index of 225 major issues listed on the Tokyo Stock Exchange's Prime section stood at 64,104.78, down 2,730.76 points, or 4.09 pct, from Thursday's closing. It slipped below 65,000 for the first time since June 12 on an intraday basis. In the Tokyo market, memory chip maker Kioxia Holdings and other key Nikkei component issues came under selling pressure. "We can't help thinking that the boom in generative AI-related stock is about to end," an official of a bank-affiliated securities firm said. END [Copyright The Jiji Press, Ltd.]
