South Korea's Kospi index fell 4% on Tuesday, marking a severe reversal for the benchmark as technology stocks faced intense selling pressure.

The decline was driven largely by Samsung Electronics, whose shares slid sharply following the company's earnings report.

The broader Kosdaq index for small-cap stocks also retreated, slipping 0.72% as investors rotated out of high-growth tech names.

In Japan, the Nikkei 225 traded marginally lower, reflecting the contagion of risk-off sentiment across Asian equity markets.

However, the broader Topix index managed to edge up 0.60%, suggesting that the selling pressure was concentrated in large-cap technology and export-oriented firms rather than the wider market.

The divergence highlights a selective purge of valuation-heavy stocks amid concerns over near-term growth trajectories.
