Market Watch: Memory Stocks Rally, Yen Pressure Returns and Equity Futures Climb in Final Trading Days of July
Global markets closed the week of July 27-31, 2026 with sharp moves across equities, currencies, commodities and digital assets. Memory chip makers led equity gains after supply warnings, AI-related names recovered following strong earnings from major technology firms, and the Japanese yen came under fresh pressure after an earlier intervention-driven surge. Equity index futures advanced while volatility eased, and Bitcoin held near recent levels amid mixed broader crypto performance.
Key Takeaways:
- Memory stocks like Micron and SanDisk rose significantly due to supply warnings from Samsung, boosting sector pricing power.
- AI-cloud stocks rebounded strongly after Microsoft’s impressive earnings, with Microsoft adding a historic $450 billion in market value.
- Meta Platforms experienced a sharp decline of nearly 10% after missing earnings expectations, impacting Mark Zuckerberg’s stake.
- Equity index futures advanced with reduced volatility; S&P 500, Nasdaq, and Dow futures all showed gains.
- The Japanese yen weakened following an intervention-driven rally, with attention on the Bank of Japan’s policy decision.
Memory Chip Shares Surge on Supply Tightness
Memory stocks recorded outsized gains this week. Micron rose 15 percent, SanDisk advanced 22 percent, Western Digital climbed 18 percent and Seagate gained 16 percent. The moves followed Samsung’s warning of tightening memory supply, which lifted pricing power expectations across the sector. The Roundhill DRAM ETF jumped 13 percent, underscoring the breadth of the rally in memory-related equities.
Semiconductor names more broadly participated. Nvidia added 2.65 percent, Micron’s 18.36 percent move stood out within the group, and AMD rose 13 percent. Avago gained 4.73 percent. These advances helped the technology sector post a 5.50 percent weekly gain, the strongest among major S&P 500 industry groups.
AI-Cloud Stocks Rebound After Microsoft Earnings
AI-cloud related shares recovered sharply in a risk-on shift. Nebius rose 27 percent, CoreWeave advanced 24 percent and Oracle gained 7 percent. The rebound came after Microsoft delivered stronger-than-expected results that lifted sentiment toward the group. Microsoft itself recorded the largest single-day market-capitalization gain ever for a U.S. company, adding $450 billion in value.
In the broader software and infrastructure space, Microsoft shares rose 15.51 percent on the week. Oracle added 8.34 percent. These gains contrasted with pressure elsewhere in technology, where Apple declined 1.41 percent.
Meta Shares Fall Sharply on Earnings Miss
Meta Platforms shares tumbled nearly 10 percent after the company reported earnings per share that missed consensus by 14 percent. Free cash flow collapsed 91 percent year-over-year on higher legal and severance costs. Raised capital expenditure guidance of $130-145 billion for AI infrastructure further weighed on the stock. The decline erased an estimated $15 billion from Mark Zuckerberg’s stake.
Communication services as a whole fell 2.68 percent on the week. Alphabet declined 0.91 percent despite beating earnings estimates, while Netflix edged lower by 0.62 percent.
Equity Futures Advance as Volatility Eases
U.S. equity index futures finished the period higher. S&P 500 futures rose 1.97 percent to 7,495.75. Nasdaq futures gained 4.20 percent to 28,489.50. Dow futures advanced 1.48 percent to 52,532.00. The VIX fell 17.28 percent to 17.09, reflecting a decline in near-term expected volatility.
Sector performance was mixed beyond technology. Consumer cyclicals rose 0.70 percent, helped by gains in Amazon (+3.90 percent) and Tesla (+3.53 percent). Industrials advanced 0.98 percent. Financial services slipped 0.56 percent, healthcare fell 1.64 percent and real estate declined 1.44 percent. Energy managed a modest 0.53 percent gain, with Exxon Mobil up 0.21 percent.
Yen Weakens After Intervention-Driven Rally Ahead of BOJ Decision
The Japanese yen came under renewed pressure on Friday after soaring in the previous session when Tokyo intervened in currency markets. The move occurred ahead of the Bank of Japan’s policy decision. USD/JPY traded near 160.52 in the latest cross rates, reflecting the dollar’s strength against the yen after the intervention-led surge faded.
The dollar itself sold off earlier in the week after second-quarter U.S. GDP missed expectations and core PCE inflation came in softer. These data points cooled bets on a September Federal Reserve rate hike. USD/JPY had plunged nearly 480 pips below 160.00 amid speculation of Japanese intervention before the later reversal. USD/CAD also weakened to a six-week low near 1.3996.
In the broader currency matrix, the euro stood at 1.15157 against the dollar, the Australian dollar at 0.70290, sterling at 1.3453 and the Swiss franc at 1.2397. The Chinese yuan traded at 6.7545 per dollar.
Oil Holds Near $84 Amid Volatile Week
West Texas Intermediate crude held near $84 after swinging more than $8 during the week. The U.S.-Iran conflict contributed to a monthly surge of roughly 21 percent, the largest since March. Shell reported that its refineries ran at 102 percent of capacity to capitalize on the price spike, supporting profits.
In the broader commodity complex, gold traded at 4,153.3 with a 0.18 percent decline. Silver stood at 59.205, up 0.32 percent. Copper fell 0.52 percent to 6.5080. Platinum rose 0.42 percent to 1,667.2. Natural gas was unchanged at 2.758. Light crude oil futures gained 0.50 percent to 84.01.
Bitcoin Steady While Broader Crypto Performance Mixed
Bitcoin traded around 64,697-64,716, up roughly 1.27 percent on the day but still below Strategy’s average cost basis of approximately 75,476 per coin. The company reported an $8.33 billion operating loss on unrealized digital-asset losses even as it increased holdings to 843,775 bitcoin and maintained its dividend track record.
Ethereum traded near 1,914.78. BNB stood at 591.22, Solana at 74.419, XRP at 1.0819 and TRON at 0.32825. Most major coins showed positive 24-hour changes on the heatmap, though gains remained measured after a challenging quarter for the asset class.
Market Sentiment Turns More Cautious
The AAII bullish sentiment reading fell to 31 percent from 45 percent in mid-July. The VIX had earlier spiked above 20 before retreating. Jim Cramer noted that sentiment had turned “vicious” as former high-flying stocks stumbled. Alphabet’s earnings beat failed to reverse the broader shift in tone.
Additional regional data provided context. Japan’s June factory output rose 1.3 percent month-on-month. Annual core inflation in Japan’s capital accelerated in July. UK business morale hit a four-month high in July according to the Lloyds survey. Mexico stated that 1.5 percent GDP growth remained secure unless the economy shrinks in the second half.
Currency Cross Rates and Commodity Backdrop
Latest major currency pairs showed EUR/USD at 1.15157, GBP/USD at 1.3453, AUD/USD at 0.70290, USD/JPY at 160.516 and USD/CNY at 6.7545. Commodity prices reflected a mixed picture after earlier volatility in energy and industrial metals.
