Sandisk is falling after earnings. Here’s what Wall Street says.

Asian stock markets experienced a surge on Wednesday, driven by a boom in AI stocks, optimistic company outlooks, and hopes for a resolution to the Iran conflict and declining oil prices. The Nikkei Index in Japan climbed approximately 3.7%, reaching its highest close in nearly two weeks at 66,300 points. The broader Topix index increased by 2.1%. Shanghai's stock exchange rose by 1.4%, while the Shanghai and Shenzhen index advanced 1.2%. South Korea's market gained 3.8%.

On Wall Street, the S&P 500 and Dow Jones hit record highs. Japanese chip maker Advantest's shares surged 8.7%, and Tokyo Electron climbed 3.3%, following the Philadelphia Semiconductor index's 6.6% rise. Murata Manufacturing, a producer of components for AI servers, saw a 9.8% jump after a profit forecast upgrade. Fanuc, a robot manufacturer, benefited from improved outlooks and gained 4.4%.

Daisuke Hashizume, a strategist at Daiwa Securities, noted that a series of profit forecast upgrades for Japanese companies are a positive factor for the overall stock market. However, Chinese AI hardware stocks saw a decline. According to Reuters, the Trump administration is considering an import ban on new models of Chinese computing center components into the US, causing shares of export-dependent optical module manufacturers Zhongji Innolight and Eoptolink Technology to drop by seven and five percent, respectively.
