Last week, earnings reports from major US technology companies showed significant divergence, leading to contrasting stock price movements. Apple Inc experienced a sharp decline after its next-quarter revenue guidance fell short of expectations, while Microsoft Corp surged on better-than-expected results, adding approximately $450 billion in market capitalization in a single day—the largest one-day gain in US corporate history.
Meanwhile, Federal Reserve Chair Jerome Powell's remarks following the policy meeting drew mixed interpretations from market participants, with analysts characterizing the signal as "dovish but confusing." On a monthly basis, major stock indices were mixed, with surface-level calm masking underlying turbulence. The Nasdaq Composite fell 3.2% in July, the Dow Jones Industrial Average edged higher, and the S&P 500 was roughly flat.
Market observers noted that the modest index-level movements concealed significant sector rotation beneath the surface, as investors reassess their technology stock allocations and brace for potential pressure from rising interest rates. The hundreds of billions of dollars that tech giants are pouring into artificial intelligence infrastructure are facing increasingly intense scrutiny from investors. Market participants indicated that shareholders are no longer satisfied with promises of "future returns" and are demanding tangible evidence of investment profitability.
Companies with strong earnings, such as Microsoft and Amazon.com Inc, saw their cloud business accelerate, with shares surging 16% and 15%, respectively. In contrast, Apple fell 7.4% due to weak guidance, while Meta Platforms Inc dropped 8% after indicating that free cash flow would turn negative in the second half of the year. Although the semiconductor sector staged a late-week rebound, the Philadelphia Semiconductor Index still posted a cumulative decline of about 21% in July.
The Federal Reserve Chair's comments at the Wednesday press conference triggered sharp volatility in both stock and bond markets. After the Federal Open Market Committee decided to hold interest rates steady, the Chair signaled that further rate hikes may not be necessary in the near term, noting that rising bond yields have already exerted a tightening effect. This statement was interpreted by the bond market as a warning sign, with the 30-year Treasury yield climbing to its highest level in 19 years, and the 10-year yield reaching an 18-month high, reflecting market doubts about the new Fed Chair's commitment to controlling inflation. The yield curve shifted upward across the board, with investors increasing bets on near-term rate hikes. Reports indicate that the Fed Chair is considering reducing the frequency of policy meetings, a move that would significantly alter the central bank's operational framework.
Rising bond yields are expected to increase financing costs for both corporations and consumers, weighing on economic growth and pressuring stock markets. At the same time, geopolitical tensions in the Middle East could push oil prices higher, exacerbating inflation risks. This week, the market will focus on key employment data and earnings reports from consumer-focused companies like McDonald's Corp and Walt Disney Co, which will provide further clues on the health of the US economy.
Despite the upward trend in yields and lingering concerns over AI-related spending, the bull market in US stocks continues to be supported by fundamental factors. The overall earnings growth rate for the S&P 500, including both reported and expected results, is around 47%, the highest in over five years, with analysts still raising their earnings forecasts for the next quarter. Analysts at Goldman Sachs Group Inc pointed out that the sharp sell-off in the memory chip sector following its early-year surge is a normal correction, and while AI spending by Amazon, Google, Meta, and Microsoft has grown significantly, they project a combined annualized revenue growth rate of 18% for these companies over the next two years. Market participants believe the US economy is still in an expansionary phase, with no clear signs of overheating, but the narrative-driven volatility around AI remains a concern.
