U. S. stock markets saw a tumultuous trading day on Friday, July 31, 2026, as investors reacted to a significant jump in bond yields and a sharp sell-off in Apple shares. Major indices like the Dow Jones Industrial Average and the S&P 500 experienced notable swings, reflecting broader market uncertainty and investor caution.
The surge in Treasury yields, with the 10-year note reaching levels not seen since January 2025, put pressure on equity valuations. This rise in yields is partly attributed to market sentiment that the Federal Reserve may not be able to bring inflation fully under control, leading to expectations of interest rates remaining higher for longer. The 30-year Treasury yield also climbed to levels not seen in two decades, further dampening investor optimism.
Adding to the market's volatility, Apple shares experienced a significant tumble. The tech giant's stock dropped sharply following its fiscal Q3 2026 earnings report, which, despite beating some revenue and earnings expectations, revealed a miss in its high-margin Services segment and weaker-than-expected results from its China business. This performance led to a roughly 10% drop in Apple's stock price at market open, wiping billions off its market capitalization and marking its worst single-day reaction to earnings in over a decade. While Amazon shares saw a substantial leap on strong earnings, the broader market sentiment was influenced by the significant moves in Treasury yields and the notable decline in Apple's valuation.
