Tech Weakness, Iran Strikes Drag Global Indexes Lower

Most stock indexes ended the week lower. Tech-sector weakness and an uncertain macroeconomic outlook weighed on markets. U.S. strikes on Iran and retaliatory actions added to the risk-off tone.

The selloff was broad, with few sectors escaping the decline. The tech-heavy Nasdaq fell more than the S&P 500, reflecting continued pressure on high-valuation names. Energy stocks initially rose on the geopolitical premium but gave back gains as the week closed.

Traders cited the lack of a clear catalyst for a reversal. The combination of stretched tech valuations and escalating Middle East tensions left little room for risk appetite. Friday's close marked the third consecutive weekly drop for the S&P 500.
