Mainland Chinese Investors Accelerate Exit from Hong Kong Stocks, October Net Selling Hits Five-Year High
nashnova research
Mainland traders net-sold roughly HK$24 billion (US$3.1 billion) of Hong Kong stocks via Stock Connect in October; the Hang Seng fell 6.7% in the same stretch, with tech names hit hardest and strategists warning the bottom may still be far off.
How much money left — and how fast?
Through Thursday, mainland traders net-sold about HK$24 billion (≈US$3.1 billion) via Stock Connect in October.
If the pace holds through month-end, it will be the largest single-month net outflow since 2021.
This means → the mainland money that historically acts as a stabiliser during Hong Kong sell-offs is now accelerating the exit, removing the market's most critical layer of buying support.
How far has the market fallen — and who got hit worst?
The Hang Seng Index dropped 6.7% in October, its steepest monthly decline since June.
The Hang Seng Tech Index fell even harder, nearly erasing all gains from Beijing's large-scale monetary stimulus in September 2024.
Tech stocks bore the brunt: SMIC, Alibaba and Xiaomi all saw heavy net selling by mainland investors.
In plain terms = the tech rally that September's stimulus ignited has effectively round-tripped to zero.
Why are investors selling?
BNP Paribas Asia-Pacific strategist Scarlett Liu noted that investors worry high capital expenditure at tech firms will compress margins.
Some consumer-electronics and EV companies face rising costs, making them so-called "memory-loss" names — stocks investors reflexively want to dump.
Macro headwinds are stacking up: fading AI hype, higher financing costs, no forceful fiscal stimulus from Beijing, and a weak start to earnings season.
China Ping An reported a sharp profit drop on lower investment returns; Tsingtao Beer missed estimates — this reflects an earnings weakness that goes well beyond individual cases.
What signals could turn things around?
Jason Lemire, CIO of Bold Wealth Partners, said persistent earnings downgrades are capping valuations.
He identified two potential turning points: ① negative earnings revisions begin to slow; ② competitive pressures ease.
In plain terms = as long as analysts keep cutting profit forecasts round after round, valuations have no floor.
How far is the market from a bottom?
RBC Wealth Management senior strategist Jasmine Duan warned Hong Kong stocks could have another 10–15% downside before a bottom is established.
She flagged U.S. Treasury yield movements and shifts in capital flows as the variables the market is most sensitive to.
Historical data show that whenever mainland fund flows turn negative, the Hang Seng tends to undergo a sustained pullback.
This means → the current sell-off may not be the final chapter — both the historical pattern and strategist assessments point the same way: the bottom is probably not here yet.
