Paul Nolte, market strategist at Murphy & Sylvest, attributed the weakness to the semiconductor sector's expanded weight in the S&P 500, noting it has grown from 8% three to four years ago to over 20% currently.
TSMC Raises Capex Guidance and Triggers SOX Index 4.29% Plunge
TSMC reported record Q2 results with net profit surging 77%, but the semiconductor bellwether's decision to raise its capital expenditure outlook from $52-56 billion to $60-64 billion sparked profit margin concerns across the sector.

Micron Technology and AMD declined 5.65% and 5.33% respectively, while Broadcom and Arm Holdings each dropped more than 5%.
