The major indices of the US stock market closed higher on Tuesday evening, after the sharp rally in chip-related stocks once again put artificial intelligence in a positive light.
The S&P 500 and the Dow Jones Industrial Average reached new highs, almost close to the 50,000 mark, setting fresh records in the regular session, with the gains concentrating more on the chip stocks.
Major Chipmakers Climb High on the Charts
In the regular trading session on Tuesday, the Dow Jones advanced by about 1%, while the S&P 500 increased by 0.6%, extending its early-year hike. The NASDAQ Composite closed on Tuesday 0.7% higher, backed by the tech and semiconductor shares.
Shares of chip makers led the market gains, mainly caused by the growing optimism about the long-term demand for AI. NVIDIA’s Chief Executive, Jensen Huang, gave a detailed outline on the details of the upcoming AI processors, featuring a new layer of storage technology designed to handle highly complex workloads.
His comments strengthened the expectations of sustained investment across the AI supply chain, elevating the shares of many semiconductor manufacturers and other memory-related companies.
SanDisk Corporation’s shares spiked by 27%, while Seagate Technology made a 14% increase, Micron Technology climbed by 10%, and Western Digital rose by 17%. All four stocks made record highs through the rally. An all-time high of 2.75% was noted on the PHLX chip index, extending its gain in the first three trading sessions of 2026 to about 8%.
Healthcare stocks also showed a positive trend, adding to the strength of the overall market, supported by Moderna. The shares of Moderna surged by almost 11% after BofA Global Research raised the price target for the mRNA technology company, which resulted in lifting the S&P 500 healthcare index by 1.96%.
Jed Ellerbroek, a portfolio manager at Argent Capital in St. Louis, commented that “I think we’re going to have a very strong earnings season for Big Tech, and all those capex estimates that we hear about are going to be revised higher again.”
European Markets Steady After Hitting New Highs
European share markets reached almost close to their record highs. However, the market showed mixed trading early Wednesday, following the major tech-driven momentum of Wall Street on Tuesday. The Stoxx Europe 600 index reached approximately 605.28.
Germany’s DAX index remained near 19,500, indicating financial strength and stability, despite the tighter policy outlook. France’s CAC 40 increased by 0.32%, reaching about 8,237.43, and the UK’s FTSE 100 jumped to 10,122.73, an increase of 1.18%.
Asian Market’s Mixed Reaction
Asian markets opened with a mixed performance on Wednesday, following Wall Street’s record performance, driven mostly by the tech giants. Japan’s Nikkei Stock Average reached around 51,996.50 after dropping 0.99%. Despite the earlier record-breaking trading sessions of Tokyo and South Korean markets, they also showed a slight decline in performance, with investors focusing more on the potential risks associated with the US Fed rate changes.
While other indexes showed a downward trend, the Hong Kong stock market hit a 1.5-month high. Other Chinese markets depicted a mixed performance, with surveys showing that the growth achieved by the market is fueling 2026 optimism.
Geopolitical Issues Create a Shift in the Market
The changing global interest rates and the political dilemma of Venezuela have gathered attention in the global stock markets, adding to the uncertainty. While the majority of the markets experienced some level of spillover optimism, every market is watching for further moves from the US government.
The volatility of the regional markets stemmed mainly from the US policy shifts and local restrictions imposed. However, the broader market sentiments improved after a strong closing in 2025, with all three major US indexes reporting impressive gains in 2026.
