Asian markets showed mixed performance on Tuesday, with Chinese stocks rebounding strongly after Lunar New Year while Hong Kong tech companies faced losses. China's CSI 300 gained 1.3% as export sectors benefited from potential lower U.S. trade tariffs following a Supreme Court ruling against Trump's tariffs.

South Korea's market jumped 1.6% to a record high, driven by chipmakers Samsung and SK Hynix, which both hit new peaks. Japan's index advanced 0.9% on exporter gains, though Australia and Singapore markets declined slightly. The broader Asian market shrugged off Wall Street's previous day losses despite ongoing tariff uncertainty.

Hong Kong's tech sector plunged nearly 2% amid AI disruption fears, with Alibaba, Baidu, and Tencent falling between 2.8% and 4.0%. Smaller AI firms like MiniMax Group and ZhipuAI bucked the trend, rising 7% and 16.4% respectively. Market participants now await NVIDIA's earnings report for further direction on AI-related investments.
