Vingroup stocks drive VN-Index up nearly 9 points, but the market experiences a "green on the outside, red on the inside" phenomenon.

Vingroup stocks were the main factor causing the market to drop nearly 15 points, its sharpest correction in over two weeks.

During the at-the-close (ATC) session, several stocks, including VHM, VPL, and MCH, simultaneously hit their floor prices due to ETF restructuring, causing the market to drop 28 points before recovering by the session's end.

Maintaining a positive trend since opening, but under pressure from Vingroup group stocks, the stock market reversed in the final minutes, dropping nearly 7 points.

Over 200 stocks on the HoSE exchange declined, led by Vingroup and Vinhomes, causing the stock market to fall by nearly 32 points during this morning's session.
