Hong Kong shares opened lower on Tuesday, tracking a broad selloff on Wall Street due to concerns over geopolitical and tariff risks, while mainland markets rallied on the first trading day of the Year of the Horse.

The city's benchmark Hang Seng Index fell 168.23 points, or 0.62 percent, to open at 26,913 points, after jumping 2.5 percent a day earlier.

The Hang Seng Tech Index retreated 1.02 percent to 5,330 points, with tech heavyweights leading the losses.

On the mainland, however, stocks opened higher as traders returned from a nine-day holiday and bid up shares across sectors from consumer electronics to machinery.

Investors are betting that the US Supreme Court's ruling against President Donald Trump's emergency tariffs would benefit Chinese exports.

The Shanghai Composite Index edged up 1.15 percent to open at 4,129 points, while the Shenzhen Component Index opened 1.52 percent higher at 14,313 points.

China's blue-chip CSI300 Index, meanwhile, rose 1.4 percent at the opening bell.

In the other major Asia-Pacific markets, Japan's Nikkei 225 advanced 0.9 percent and South Korea's Kospi climbed 1.1 percent, while Australia's S&P/ASX 200 gave up 0.2 percent. (Xinhua/Reuters)
