Hong Kong’s stock market is watching investors head for the exits. In the week ending June 3, 2026, mainland-listed ETFs tracking Hong Kong equities saw record outflows of 25 billion yuan, roughly $3.7 billion, as capital rotated into China’s onshore AI supply chain and semiconductor companies.

The numbers tell the story

In May 2026, onshore investors sold a cumulative HK$3.6 billion (about $459 million) of Hong Kong stocks through Stock Connect. That marked the first monthly outflow through the cross-border trading link in three years.

Goldman Sachs has taken notice. Around June 3, the bank downgraded H-shares, the designation for mainland Chinese companies listed in Hong Kong, and pivoted its recommendation toward onshore AI hardware investment opportunities.

The Hang Seng Tech Index, which had posted strong performance earlier in 2026, has been caught in the downdraft. Major names like Tencent and Alibaba have faced considerable selling pressure as capital flows favor mainland-listed counterparts or pure-play AI infrastructure companies trading on Shanghai and Shenzhen exchanges.
