U.S. stocks rise on Friday to end a volatile July as investors weigh corporate moves against ongoing inflation worries. Multiple outlets report that Amazon shares surge, lifting overall market sentiment, while Apple shares fall, weighing on the indexes. The broader market edges higher into the close, with the S&P 500 posting a gain for the day as traders look toward how inflation trends could affect interest-rate expectations.

Inflation concerns remain central to the market outlook, with rising oil prices cited as a factor that could keep inflation elevated. That development adds to fears that cost pressures may persist rather than cool, influencing how investors value equities. The combined picture—strong performance from some large-cap companies alongside declines in others, and renewed attention to energy-driven inflation risk—shapes the final trading session of the month. The day’s moves contribute to how Wall Street finishes July, characterized as “wild” due to sharp swings and shifting expectations.
