Zai Lab (09688) is set to continue its upward trajectory, soaring 6.60% in pre-market trading on Friday. This follows a remarkable performance on Thursday when the stock surged over 12% in the US market, reflecting a broader rally in Chinese concept stocks.

The impressive gains come amid a resurgence of interest in Chinese equities. The Nasdaq Golden Dragon China Index rose over 2% on Thursday, with several Chinese stocks posting significant advances. This uptick is part of a larger trend, as Morgan Stanley reports that US investor interest in Chinese stocks has reached its highest level in five years.

Factors contributing to this renewed enthusiasm include China's leadership in specific industries, government efforts to boost stock markets and stabilize the economy, improved liquidity conditions, and increasing investor demand for portfolio diversification. The Institute of International Finance further supports this trend, reporting that foreign investors poured nearly $45 billion into emerging market equity and bond portfolios in August, with Chinese market portfolios receiving the lion's share of these inflows.
