US equity markets opened significantly lower on Tuesday, with technology shares leading the decline.

The Nasdaq Composite fell 2.1% at the open, signaling renewed risk aversion among investors.

Memory chip maker Micron Technology was among the names under pressure as the sell-off broadened across the sector.

The drop extended losses from the previous session, driven by a broad-based retreat in technology stocks.

US equity futures had pointed to a sharply lower open, with the Nasdaq 100 tumbling 2.8% and the S&P 500 declining 1.4% in pre-market trading.

The move reflects growing investor caution regarding the elevated valuations of major artificial intelligence names.
