Tokyo's Nikkei Stock Average experienced fluctuations over the past two days, initially opening lower due to losses in U.S. technology stocks and concerns over semiconductor shares. On February 26, the index fell by 95 points, reflecting caution surrounding U.S. economic uncertainties and anticipated earnings from Nvidia. However, on February 27, the Nikkei rebounded, gaining 113 points as investors showed renewed interest in semiconductor stocks following Nvidia's strong growth forecast, despite Advantest's stock struggling amid mixed trading. The day's trading results indicated a recovery in the market, but Advantest's performance remained a concern as it did not benefit from Nvidia's positive outlook.
