US stock futures were little changed on Wednesday as investors awaited another busy round of corporate earnings, with Alphabet, Tesla, GE Vernova, Philip Morris, and Texas Instruments among the major companies scheduled to report. In extended trading, Super Micro Computer surged nearly 20% after posting stronger-than-expected profitability and unveiling a record order backlog driven by robust demand for its AI-optimized servers. Meanwhile, Pegasystems tumbled more than 13% after the software firm delivered second-quarter results that missed Wall Street estimates. During Tuesday’s regular session, the Nasdaq Composite advanced 1.29%, while the S&P 500 and Dow rose 0.89% and 0.74%, respectively. Chipmakers led the rally after strong export data from Taiwan and South Korea boosted confidence in the sector. Solid earnings from blue-chip companies, including 3M and General Motors, also helped ease concerns about the strength of corporate America.

The Dow Jones Index gained 384 points or 0.74 percent on Tuesday to close at 52223 points. Gains were led by 3M (7.60%), UnitedHealth (3.39%) and Caterpillar (2.91%). Biggest losers were Boeing (-2.25%), Sherwin-Williams (-1.87%) and Alphabet (-1.64%).

US stock indices closed higher on Tuesday as a rally in chipmakers lifted the broader market. The S&P 500 added 0.9%, the Nasdaq 100 advanced 1.9%, and the Dow Jones gained 385 points. Semiconductor stocks extended their rebound from last week's rout after strong export data from Taiwan and South Korea reinforced optimism for the sector. Nvidia gained 2% after saying its latest chip designs are reaching customers, while Intel climbed 8.6% on plans for job cuts. Micron (+12.2%), Sandisk (+14.3%), and AMD (+8.1%) surged. The sector rallied ahead of Alphabet's (-1.4%) earnings on Wednesday, which are expected to provide fresh signals on AI infrastructure demand from hyperscalers. Meanwhile, other sectors stabilized despite further escalation between the US and Iran and the resulting rise in oil prices. Treasury yields remained elevated, limiting gains in financial stocks. Elsewhere, GM rose 4.9 % after reporting earnings, while Charles Schwab fell 2.5% after missing estimates.
