Tokyo, May 27 (Jiji Press)--Japan's benchmark Nikkei 225 stock average staged a rebound to briefly top 66,000 for the first time on Wednesday morning, buoyed by overnight gains in U.S. technology stocks. At 9:06 a.m., the index of 225 selected issues listed on the Tokyo Stock Exchange's Prime section hit a high of 66,428.81, up 1,432.72 points, or 2.20 pct, from Tuesday. The broader TOPIX index on the TSE also reached a record intraday high, at 3,971.77. In the U.S. market on Tuesday, semiconductor-related stocks attracted purchases, with Micron Technology surging on the back of strong demand for memory chips used at artificial intelligence data centers. Semiconductor and electronic component-related stocks drew purchases in the Tokyo market as well on Wednesday. After the initial wave of buying ran its course, however, profit-taking selling emerged, forcing the Nikkei to trim its gains, market sources said. END [Copyright The Jiji Press, Ltd.]
