The stock market ended a volatile July with gains as Amazon shares surged nearly 9% in after-hours trading on July 30 after the tech giant reported stronger-than-expected second-quarter earnings of $5.75 per share on revenue of $200.6 billion, according to Reuters and CNBC.
Amazon’s earnings beat came as investors weighed Big Tech results against concerns about artificial intelligence spending. The company’s cloud division, Amazon Web Services, showed strong momentum, which boosted confidence in the company’s ability to manage its capital expenditure plans even as it increases AI infrastructure investment.
July proved a turbulent month for equities overall. The Nasdaq-100 fell approximately 7% for the month, recording its steepest monthly decline since March 2025, while the Dow rose 0.3%, according to CNBC. The equal-weighted S&P 500 outperformed the Nasdaq during the period, signaling a rotation away from the most expensive technology stocks.
The month’s volatility reflected investor caution around Big Tech earnings and the Federal Reserve’s policy stance. According to the Wall Street Journal, earnings beat expectations, yet equity markets grew volatile as traders grappled with whether companies could justify massive capital outlays for AI infrastructure. Alphabet’s strong earnings were overshadowed when the company projected a $15 billion increase in 2026 capital expenditures, sparking investor unease, according to Forbes.
Historically, July has been a strong month for stocks. Since 2005, the S&P 500 has averaged a 2.5% gain in July, more than four times the advance in the other 11 months, according to Bloomberg. However, 2026’s July demonstrated that even historically favorable months can test investor patience when earnings season coincides with concerns about corporate spending priorities and monetary policy.
Amazon’s rally reflected investor relief that at least one mega-cap technology company was delivering both earnings growth and a credible capital allocation strategy. The company’s shares gained 3.9% during the regular trading session on July 30 before climbing further after-hours, according to Reuters.
