Tech Stocks Decline as Semiconductor Selloff Extends Through Mid-July
Global technology equities weakened over the week ending July 20, 2026, led by sharp declines in semiconductor and AI-related shares amid valuation concerns and profit-taking. The Nasdaq Composite fell 2.9% while the VanEck Semiconductor ETF dropped nearly 9%, marking its third consecutive weekly loss. Geopolitical tensions between the US and Iran added pressure through higher oil prices and inflation worries, though select earnings such as TSMC's 36% sales increase highlighted underlying demand strength. Investors monitored rotation away from high-valuation names toward broader market segments.
