The U.S. stock market swung sharply on Friday as Wall Street continued its volatile month with vastly different performances from technology giants and mounting concerns about inflation spreading through rising oil prices and bond yields.
Amazon shares surged as the company reported better-than-expected second-quarter earnings driven by strong cloud computing growth. The e-commerce and cloud services giant climbed roughly 12 to 14 percent during the session after revealing that its AWS cloud division delivered its fastest growth in 18 quarters. The earnings beat marked a stark contrast to recent losses in the technology sector and offered some reassurance to investors worried about returns on massive artificial intelligence infrastructure spending by major corporations.
Apple, meanwhile, stumbled sharply in the opposite direction. The iPhone maker dropped approximately 7 to 9 percent after issuing disappointing guidance for its current quarter due to supply constraints in memory chips and weakening revenue outlooks for key segments including services and China operations. The sharp divergence between the two megacap stocks illustrated how markets are beginning to differentiate between technology companies benefiting from artificial intelligence spending versus those experiencing headwinds from the global chip shortage affecting hardware makers.
As the day progressed, gains narrowed considerably as surging Treasury yields weighed on equities. The 10-year Treasury note climbed to 4.737 percent in intraday trading, reaching its highest level since January 2025, while the 30-year Treasury yield approached 5.22 percent, a level unseen since 2007. The sharp moves in bond markets underscored investor anxiety about inflation and the Federal Reserve’s monetary policy stance.
By midday, the broad market indexes showed more modest gains. The S&P 500 rose 0.2 percent, the Dow Jones Industrial Average was up roughly 80 points or 0.2 percent, and the Nasdaq Composite climbed 0.4 percent after briefly losing earlier gains. The market had started the day with stronger momentum, with early gains of up to 0.7 percent before retreating as bond yields surged and Apple weakness spread.
Oil prices continued adding to inflation concerns, climbing on escalating geopolitical tensions in the Middle East. West Texas Intermediate crude rose 1.9 percent to reach 85.15 dollars per barrel, while Brent crude surged 1.3 percent to 90.15 dollars per barrel. The price increases reflected renewed hostilities affecting the Strait of Hormuz, a critical chokepoint for global crude shipments. Iran’s Revolutionary Guard claimed it had struck tankers attempting to pass through the waterway under U.S. military escort and forced additional vessels to turn around.
The situation in the Middle East adds a supply-driven component to inflation concerns that has rattled markets throughout July. Rising energy costs can trickle through the broader economy, affecting transportation and manufacturing expenses while complicating the Federal Reserve’s battle against inflation. Some market analysts expressed concern that persistent geopolitical tensions could force the central bank to consider rate hikes rather than cuts, particularly if oil prices remain elevated or climb further.
Friday’s market action reflected broader July turbulence that has kept Wall Street on edge. The month has been marked by whipsawing swings between optimism on strong earnings from technology and financial sectors and pessimism over inflation risks, rising bond yields, and geopolitical tensions. Earlier in the week, the Federal Reserve held interest rates steady but signaled inflation remained sticky, prompting a sharp sell-off when some investors interpreted the decision as indicating the central bank was falling behind in its inflation-fighting efforts.
The earnings season has provided some mixed signals. While companies like Amazon and Microsoft have demonstrated that artificial intelligence investments are beginning to pay off through accelerating cloud growth, others face challenges. Apple’s guidance disappointed despite showing strong iPhone sales, highlighting how AI-related supply constraints are creating winners and losers across corporate America.
Bond market anxiety stands out as a particular concern. Rising Treasury yields typically pressure stock valuations, especially for growth stocks dependent on low interest rates. Investors are pricing in expectations that the Fed may need to hold rates higher for longer if inflation doesn’t cool sufficiently, a scenario that could slow economic growth while prices remain elevated.
