U.S. equity markets showed resilience during afternoon trading on Friday, July 31st, 2026, as investors navigated a heavy slate of corporate earnings and monitored shifting dynamics in the bond market. While the broader market indices trended upward, performance remained bifurcated, with high-growth technology and consumer discretionary sectors leading the charge while materials and small-cap stocks faced selling pressure.
Major Index Performance
As of mid-afternoon, the tech-heavy Nasdaq Composite, tracked by the Invesco QQQ Trust (QQQ), was the standout performer, rising 0.79%. The S&P 500, represented by the SPDR S&P 500 ETF Trust (SPY), gained 0.57%, while the Dow Jones Industrial Average via the SPDR Dow Jones Industrial Average ETF Trust (DIA) followed closely with a 0.55% advance.
In contrast, the small-cap segment struggled to keep pace. The iShares Russell 2000 ETF (IWM) slipped 0.31%, suggesting that the afternoon rally was largely concentrated in large-cap "magnificent" names rather than the broader market. In the fixed-income space, long-term yields saw upward pressure, causing the iShares 20+ Year Treasury Bond ETF (TLT) to drop 1.00%.
Sector Highlights and Afternoon Activity
Sector performance was dominated by the Consumer Discretionary Select Sector SPDR ETF (XLY), which surged 3.41% following strong retail and e-commerce sentiment. The artificial intelligence theme also remained a primary driver for investors, with the iShares A.I. Innovation and Tech Active ETF (BAI) climbing 1.91% and the VanEck Semiconductor ETF (SMH) rising 1.33%.
However, it was a difficult session for commodities and defensive plays. The Materials Select Sector SPDR ETF (XLB) tumbled 2.05%, while the VanEck Gold Miners ETF (GDX) fell 3.28% as gold prices retreated. The SPDR Gold Trust (GLD) was down 1.45% in afternoon action.
Major Corporate News and Tickers
Corporate earnings were the primary catalyst for individual stock volatility. AbbVie Inc. (ABBV) reported its Q2 2026 results before the opening bell, posting an estimated EPS of $3.77. In the tech sector, Amazon.com Inc. (AMZN) saw massive afternoon activity, with its stock price jumping 12.6% on significant volume.
Nvidia (NVDA) and other semiconductor giants continued to see high engagement, though Apple Inc. (AAPL) faced some headwinds, with its stock price down 8.6% amid a heavy trading volume of over 77 million shares. Micron Technology, Inc. (MU) bucked the trend among hardware names, rising 5.2%.
In the premarket and early afternoon "movers" category, Focus Universal Inc. (FCUV) saw an astronomical rise of 432.6%, while Replimune Group, Inc. (REPL) more than doubled, gaining 108.3%. On the downside, Karyopharm Therapeutics Inc. (KPTI) plummeted 68.6% following disappointing clinical or corporate updates.
Upcoming Market Events
Investors are looking ahead to a packed economic calendar next week. On Monday, August 3rd, the market will brace for after-hours earnings from Vertex Pharmaceuticals Inc. (VRTX) and Axon Enterprise, Inc. (AXON).
The most anticipated event of the coming week arrives on Tuesday, August 4th, when Advanced Micro Devices (AMD) is scheduled to report its Q2 results after the close. With a market cap nearing $950 billion, AMD’s results will be a critical litmus test for the sustainability of the AI-driven bull market. Other notable upcoming reports include Caterpillar Inc. (CAT) and Arista Networks (ANET). Market participants also remain focused on potential Federal Reserve commentary regarding inflation and the future path of interest rates as the third quarter progresses.
