ZIJIN GOLD INTL (02259) experienced a significant surge in its stock price, soaring 6.86% during intraday trading on Thursday. The sharp increase comes on the heels of a major announcement by MSCI Inc. regarding its November index review adjustments.

According to the announcement made early Thursday, ZIJIN GOLD INTL is one of nine Hong Kong-listed stocks newly added to the MSCI China Index. This inclusion is part of a broader adjustment to the index, which also saw changes in its China A Index components. The changes are scheduled to take effect after the market closes on November 24, 2025.

The inclusion in the MSCI China Index is likely to boost ZIJIN GOLD INTL's visibility among international investors and could potentially lead to increased demand for its shares. Index inclusions often result in passive funds that track the index purchasing shares of newly added companies, which can contribute to positive price movements. Investors appear to be reacting positively to this news, as evidenced by the substantial increase in trading volume, which reached HK$243 million by mid-morning.
