Stocks on Wall Street saw a rebound on Wednesday, with the S&P 500 index rising 0.5% and the Dow Jones Industrial Average gaining 0.5% (270 points), snapping a three-day losing streak. The Nasdaq Composite also increased by 0.5%. This uplift in market sentiment was largely attributed to a pause in the rally of oil prices, which retreated below $90 a barrel, alleviating some concerns about inflation fueled by recent geopolitical tensions between the U.S. and Iran. The U.S. had attacked sites in Iran over the weekend, leading to retaliatory actions and renewed fears of a broader regional conflict affecting oil supplies.

The recovery was also bolstered by strong performances from certain companies, particularly those in the artificial intelligence sector. Dell Technologies surged 6.9% to 14% after raising its sales forecast by $25 billion and providing an encouraging financial outlook, crediting strong demand for AI servers. GitLab's shares also soared 13% following higher revenue guidance. In contrast, Credo Technology fell 18%, MongoDB dropped 12%, FuelCell Energy plummeted 17%, and G-III Apparel slid 9.4% due to disappointing sales or forecasts. Brown-Forman, the maker of Jack Daniel's, rose 4.2% after beating first-quarter profit estimates.

Investors are closely monitoring upcoming economic data, especially Friday's jobs report and next week's inflation data, as these will significantly influence the Federal Reserve's decision on interest rates. The market is currently pricing in a 64% to 66.2% chance of a September rate hike, a significant increase from 37% a week prior. Fed Chair Kevin Warsh's recent comments emphasizing inflation control as the central bank's primary focus, coupled with elevated U.S. Treasury yields, have heightened expectations for further monetary tightening. The 10-year Treasury yield rose slightly to 4.80%, near its highest since January last year. Despite the day's gains, overall investor sentiment remains cautious due to these factors, along with seasonal weakness typically seen in September for equities.
