U.S. equity futures are pointing to a lower open on Tuesday, driven by a broad selloff in South Korean stocks that is spilling over into American markets.

The Nasdaq Composite is particularly vulnerable, with futures indicating a sharp decline as investors digest the weakness emanating from Asia.

The contagion effect highlights the interconnectedness of global technology markets.

As major Korean tech exporters face selling pressure, U.S. counterparts are being dragged down in sympathy, reflecting broader risk-off sentiment among traders.

The move suggests that regional headwinds in Asia are no longer contained and are beginning to impact global liquidity and sentiment.

This development adds to a week of volatility for growth stocks.
