Stock market session October 21: VN-Index breaks out again, foreign investors net pour in more than 2,400 billion VND

After a strong decline at the beginning of the week, the market recovered. Although pressure remains, green still plays a dominant role.

In today's trading session (October 21), money flowed in with the bottom-fishing mentality after a historic decline yesterday. The market was positive but the hesitant mentality remained. Although the index increased for most of the morning session, at the end of the session, the active selling pressure increased, forcing the index to temporarily stop in the morning session below the reference level.  

In the afternoon session, the market quickly reversed with active buying power rising and becoming overwhelming. VN-Index increased to 1,677.11 points at one point, then adjusted to close at 1,663.43 points, equivalent to an increase of 27 points (+1.65%).

It has been a long time since investors have seen purple in this stock. The most recent session with a similar increase occurred in April 2025 along with the general effect of the market recovering after a sharp decline due to tariff information. At that time, FPT's market price was still above 110,000 VND/share.  

With today's breakthrough, FPT was almost the biggest contributor to the VN-Index's increase, until VIC surged again in the afternoon session, ending up 4.36% and becoming the biggest "contributor". VIC and FPT alone contributed nearly 10 points to the VN-Index's increase today, and the 10 stocks that most influenced the index contributed 24.5 points, namely VIC, FPT, HDB, HVN, LPB, VHM, HPG, VPB, MWG, SSB.
