Hong Kong Tracker Fund, one of the largest exchange-traded funds in the city, will stop investing in some Chinese stocks to comply with a US government order, but market participants say this is unlikely to have an immediate impact on money flowing into the fund. US President Donald Trump issued an executive order on November 12 prohibiting US investment in 31 Chinese companies deemed to be affiliated with the Chinese military. Three companies on the blacklist – China Mobile, China Unicom, and China National Offshore Oil Corporation – are constituents of Hong Kong’s Hang Seng Index. The Tracker Fund, which is benchmarked against the index, is managed by State Street Global Advisors Asia.
