Cooling inflation lifts U.S. stocks as AI capital rotates into memory.

The S&P 500 gains 0.7% to a record while Taiwan and TSMC fade about 0.1% and 0.4% at midday. TraderXYZ top-ten volume reaches $3.065 billion before retail sales test the soft landing.

Core Takeaway

U.S. July CPI slows to 3.4% year over year and core CPI to 2.5%, while headline and core PPI stand at 4.7% and 4.2%. Cooling inflation reduces immediate hike pressure, but core PCE may remain near 3.3%; this is policy relief, not an easing cycle.

The S&P 500 gains 0.7% to a record and technology broadly advances, while small caps add only about 0.2%. Risk appetite remains concentrated in mega-cap technology and AI, leaving retail sales to decide between a soft landing and renewed stagflation concern.

TSMC and the Memory Rotation

TSMC July revenue reaches TWD 467.58 billion, up 44.7% year over year and 5.6% month over month; January-July sales rise 37% to roughly TWD 2.872 trillion. Fundamentals remain strong, but TSMC fades about 0.4% at midday as high expectations still need price confirmation.

TraderXYZ top-ten notional reaches about $3.065 billion, up roughly 38% from the prior comparable brief. SNDK, MU, DRAM and SKHY are all active, showing AI bottlenecks spreading from GPUs into HBM and memory, although perpetual leverage magnifies moves.

Opportunity continues to broaden into advanced packaging, networking, equipment, power and cooling. Equipment orders and hyperscaler cash returns provide better evidence of capex durability than a single trading session.

Next Confirmation

Watch U.S. retail sales and Michigan inflation expectations tonight, then whether core PCE remains above 3%. Stable consumption with moderate inflation would provide more complete support for technology valuations.

Track whether TSMC holds TWD 2435-2440 and validate the memory rebound through MU, SNDK and DRAM-linked U.S. cash trading, SOXX / SMH and options volume. Valuation and leverage remain the main risks.
