VN-Index rose slightly on derivatives expiration day.

In contrast to the violent fluctuations often seen during derivatives expiration sessions, the stock market on December 18th was relatively calm. The VN-Index maintained a slight upward trend thanks to support from the aviation sector and some banking stocks, despite strong net selling by foreign investors.

As the December futures contract expiration session began, a cautious sentiment prevailed in the market. Investors limited large trades to observe the performance of blue-chip stocks, resulting in a noticeable decrease in liquidity compared to the previous surge.

At the close of trading on December 18th, the VN-Index rose 3.32 points to 1,676.98 points. The VN30 index also increased by 5.52 points, reaching 1,903.47 points, indicating relative stability among large-cap stocks on the day the derivatives market closed.

Liquidity continues to be a drawback, with the total trading value on the HOSE reaching only VND 17,764.95 billion, significantly lower than recent sessions. Large capital flows remain inactive, awaiting clearer trend signals.

The most outstanding highlight in the VN30 basket was airline stock VJC. This stock unexpectedly surged, rising 4.8% to VND 193,900 per share, becoming the stock contributing the most points to the VN-Index during the session. The banking sector also helped support the market, with HDB rising 3.4% in the ex-dividend trading session; other stocks such as STB (up 1.7%), TCB (1.2%), and VPB (1.1%) maintained their upward momentum. However, this consensus was not widespread, with BID remaining unchanged and CTG slightly declining by 1%.

Contrary to the general trend, shares of Duc Giang Chemical Group Joint Stock Company (DGC) continued to be the focus of negative sentiment, falling to the floor price for the third consecutive session, down to 74,900 VND per share. By the end of the session, nearly 22 million shares remained unsold at the floor price, amidst unverified rumors circulating in the market. In just three trading sessions, DGC's market capitalization has evaporated by nearly 6,900 billion VND.

In other sectors, divergence was evident. The securities sector saw AGR rise over 6%, VND increase 2.7%, while VIX fell 1.1%. The large real estate sector stalled after a series of sharp fluctuations, with VHM remaining at its reference price, VIC slightly down 0.1%, and VRE rising 2.2%.

Foreign investor activity continued to put pressure on the market as foreign investors sold heavily, with a net selling value of over 850 billion VND on the HOSE. The selling pressure was concentrated on blue-chip stocks such as VIC (approximately 331 billion VND) andFPT (nearly 95 billion VND), thereby somewhat hindering the index's recovery.

Overall, the VN-Index maintained its positive momentum on the derivatives expiration day thanks to the support of several large-cap stocks. However, low liquidity and net selling pressure from foreign investors indicate that cautious sentiment still dominates the market, while short-term risks have not been fully eliminated.
