The S&P 500 rose Wednesday, boosted by tech shares after a federal court decision in an Alphabet antitrust case fueled optimism that the tech giants will be able to weather regulatory threats.
The tech-heavy Nasdaq Composite gained 1.03% to end the day at 21,497.73, while the S&P 500 climbed 0.51%, to finish at 6,448.26. The Dow Jones Industrial Average lagged, falling 24.58 points, or 0.05%, to settle at 45,271.23.
Shares of the Google parent jumped 9.1% after a federal judge ruled Tuesday that Google can keep its Chrome browser but won't be allowed to strike exclusive search deals and must share its search data. The decision avoided the worst-case outcome for the tech giant, and largely drew from the idea that artificial intelligence has provided more choice to consumers.
"This was clearly a clearing event for GOOGL shares, and we continue to like the stock," Mark Mahaney, Evercore ISI head of internet research, said on CNBC's "Squawk on the Street." "This distraction is behind us. Now, you can focus on the fundamentals, and valuation, I think, is still highly attractive."
The decision also means that Apple can continue to preload Google Search onto its iPhones, which is a lucrative arrangement for Apple. The company, which also is facing its own antitrust case, saw its stock rise 3.8%.
Wednesday's comeback was led mostly by tech, which is why the less-tech-focused Dow was lower. Shares of energy and bank shares were weak as concern lingered about a slowing economy and jumping bond yields.
Concern pertaining to the economy was heightened Wednesday after the latest jobs openings data showed a decline to levels rarely seen since the Covid pandemic. That places increased emphasis on the August jobs report due Friday as the next major test for stocks.
September trading began on a negative note, with stocks losing momentum during Tuesday's trading session. Each of the three major U.S. indexes ended the session in the red as investors raked in profits from the summer rally.
Tuesday also saw a spike in bond yields as traders weighed the consequences of a federal appeals court's ruling Friday that many of President Donald Trump's global tariffs are illegal. The decision could force the U.S. to refund the billions brought in from trade duties.
September is a typically weak month for U.S. equity performance. Scott Wren, senior global market strategist at Wells Fargo Investment Institute, said that September has been the worst month for the S&P 500 since 1950, averaging a loss of 0.7%.
"Stocks are entering September with a time out from the recent calm," Wren said. "Market volatility should increase, especially equities and short- & long-term fixed income, while economy slows, tariff impacts arrive piecemeal, and political uncertainties continue."
