Foreign investors sold a net VND10.8 trillion of Vietnamese shares over ten consecutive sessions, according to VnExpress figures updated on October 6. The amount is equivalent to roughly $420 million. In the latest session, foreign purchases were about VND2.1 trillion and sales nearly VND4.9 trillion. The outflows followed the market's classification upgrade, but the timing alone does not establish that the upgrade caused them. Explanations involving fund rebalancing and global capital movements remain analysts' assessments rather than guarantees about future trading.
