Around midmorning on the 21st, the Nikkei narrowed its gains. Buying spread to AI and semiconductor stocks, while gains in Advantest and Tokyo Electron narrowed.
In the Tokyo stock market around midmorning on the 21st, the Nikkei Stock Average narrowed its gains and was trading around ¥64,800, approximately ¥750 above the previous day. It had briefly risen to around ¥65,400, but selling by investors waiting for a rebound became dominant when it moved above the ¥65,000 milestone. Advantest and Tokyo Electron, which have a significant impact on the index, narrowed their gains.
Buying spread to AI and semiconductor stocks after the December contract of Nasdaq-100 futures rose in the US, but as the index futures quickly lost momentum, profit-taking selling intensified in Tokyo as well, bringing the Nikkei's advance to a pause.
Market participants said the Nikkei's rise was no more than buying aimed at an autonomous rebound, while concerns over excessive AI investment remain strong. Some said they wanted to assess the earnings announcements.
As of 10 a.m., estimated trading value on the TSE Prime market was ¥2.1778 trillion, with trading volume of 659.65 million shares. By stock, SBG, Ibiden and Kioxia rose, while Fast Retailing fell. KDDI, Nitori Holdings and Aeon declined.
