US Tech Stocks Tumble on AI Concerns, Middle East Tensions

Technology stocks bore the brunt of selling pressure in US markets, with the Nasdaq and S&P 500 both ending significantly lower as investors reconsidered the sustainability of recent AI-driven rallies. The pullback reflects growing scepticism about near-term earnings growth in the sector, which has dominated market gains throughout the year.

Concerns about geopolitical instability in the Middle East added to the selling pressure, with analysts warning that regional tensions could support higher crude oil and energy prices. This prospect has intensified worries among market participants that inflation may prove stickier than previously anticipated, complicating the Federal Reserve's monetary policy outlook.

The persistence of inflationary pressures would likely force US policymakers to maintain restrictive interest rate settings, a scenario that weighs particularly heavily on technology and growth-oriented stocks, which are most sensitive to higher borrowing costs. Investors have grown increasingly anxious that the recent rally in megacap tech names may have run ahead of fundamentals, prompting profit-taking and repositioning.

The market decline signals a shift in sentiment from the optimism that characterised earlier sessions, as traders balance enthusiasm for artificial intelligence developments against macroeconomic headwinds. Regional investors and exporters closely watch US market movements and interest rate expectations, given their significant impact on Asian economies and currency valuations.
