The Nikkei Stock Average experienced a notable rebound on January 7, 2025, rising by 776 yen to close at 40,083.30 yen. This increase was driven primarily by a surge in semiconductor-related stocks, which were buoyed by positive performance in U.S. tech stocks. The index temporarily surpassed the 40,000 yen mark during trading, a level not seen since December 30, 2024. Reports indicated that at one point, the Nikkei had risen by as much as 900 yen. However, the following day, January 8, the index faced a decline, opening down by 102 yen and closing at 39,981.06 yen, attributed to a drop in U.S. tech stocks and profit-taking by investors. On January 9, the Nikkei continued its downward trend, opening at 39,678.93 yen, down 302.13 yen, as concerns over U.S. tariffs and semiconductor regulations weighed on market sentiment.
