China stocks staged a cautions rally Wednesday but still face daunting obstacles to any sustained rise.

After U.S. markets surged higher overnight, Hong Kong’s Hang Seng Index rose 1.9%, 336 points, to 18,416 in thin pre-holiday turnover. The index of Chinese companies gained 2.2% to 9,951.

The Hang Seng was up 400 points at one time, but falling prices on Mainland Chinese markets eroded some gains. Chinese A-shares have been sinking for months, which is a major drag on Hong Kong prices because many investors think the decline signals furthers weakness in China’s economic growth.

That worry is one reason Wednesday’s rebound probably will be short-lived. “Uncertainty over European debt and the Chinese economic downturn is the major reason investors are not entering the market in this holiday season,” said Castor Pang, head of research at Core Pacific Yamaichi.

Stocks in Hong Kong will probably drift in a small range to the end of the year, he told Equities, but may stage another short-term rebound early next year when investors adjust their portfolios.

Export-related stocks like Li & Fung (LFUGY) should benefit because of encouraging news about the U.S. economy, according to Pang.

The banking sector stands to gain the most, he said. Bank of China (BACHY) and the Agricultural Bank of China (ACGBY) are the best bets for the short-term, Pang said, but value investors lean toward ICBC (FXI) and CCB (CICHY). End
