US semiconductor equities faced heavy selling pressure on Tuesday, extending losses that began in Asian trading sessions.

The decline marks a sharp reversal for a sector that has more than doubled in value since hitting lows triggered by geopolitical tensions earlier in the year.

A key index of chip manufacturers fell 7% in the session, underscoring growing investor caution regarding the sustainability of the artificial intelligence boom.

The sell-off was broad-based, sweeping through major technology shares and triggering widespread doubt among traders about the current valuation levels.

While the sector had previously benefited from robust demand narratives, the recent price action suggests a shift in sentiment as investors reassess risk.

The move reflects a broader repricing of growth assets amid heightened uncertainty.
