US stocks finished Thursday in positive territory, according to market data cited by ChainCatcher from Gate. The Dow Jones Industrial Average was preliminarily up 1.19% at the close, while the S&P 500 gained 1.67% and the Nasdaq climbed 2.78%. Semiconductor-related names posted some of the strongest moves of the session. Micron Technology rose 18%, Sandisk jumped 26%, and SK Hynix added 17%. Nvidia also advanced by more than 2%. Chinese stocks listed in the US also moved higher, with the Nasdaq Golden Dragon China Index up 1.05%. Among individual names, iQIYI gained 4%. The report was presented as a market snapshot and did not provide additional commentary beyond the quoted index and stock performance figures.

U.S. stocks reversed sharply late on July 30 after President Donald Trump said the U.S. was ready to respond following Iran’s missile launch at American troops in the Middle East, wiping out earlier gains and pushing the Nasdaq 100 more than 11% below its June high. That move officially put the index in correction territory. Earlier in the session, the Federal Reserve left rates unchanged, but the decision included three dissenting votes in favor of hiking, an unusual split that added to pressure across rates markets. Fed Chair Warsh declined to offer forward guidance on the next meeting, while the 30-year Treasury yield climbed above 5.2%, its highest level since 2007. The day also brought a stark split in Big Tech earnings. Microsoft rose more than 8% in after-hours trading after reporting fiscal fourth-quarter revenue of $90.01 billion, up 18% year over year and above the $87.72 billion market expectation, with adjusted EPS of $4.74 and Azure growth at its fastest pace since 2022. Meta fell more than 10% after hours even though second-quarter revenue rose 28% to $60.8 billion, as EPS of $6.18 trailed the prior year’s $7.14 and the midpoint of its third-quarter revenue guidance came in below analyst estimates. Chip stocks stayed under heavy pressure for a fifth straight session, while crypto prices were relatively calm, with Bitcoin opening at $63,853.49 and Ether at $1,919.73.

U.S. stocks finished mixed on Wednesday, according to market data cited by ChainCatcher from Gate. The Dow Jones Industrial Average was initially down 0.01%, while the S&P 500 fell 0.14% and the Nasdaq declined 0.57% by the close. Among individual names, SpaceX (SPCX.O) dropped 6.7% and set a new closing low. Nvidia (NVDA.O) gained 2.3%, while SK Hynix (SKHY.O) fell 3.8%. Super Micro Computer (SMCI.O) jumped nearly 20%, and Dell (DELL.N) rose 9%. The Nasdaq Golden Dragon China Index closed down 1.8%, with NetEase (NTES.O) falling more than 6%. The move reflected a mixed session across major U.S. benchmarks and several closely watched technology-related stocks.

ChainCatcher reports that US regulators are investigating insider trading allegations brought by Susquehanna International Group, which claims unknown traders made $100 million in options profits before China's regulatory crackdown on cross-border brokerages Futu Securities and Tiger Brokers. Susquehanna, acting as counterparty, lost over $70 million and has obtained a court order to freeze related accounts. The SEC is reviewing the trades described in the lawsuit, which targeted options expiring after the May 22 regulatory announcement that led to Futu being fined 1.85 billion RMB and its founder losing $1.7 billion in a single day.
