HLB (028300) is drawing investors' attention after suddenly surging in after-hours trading on the 30th following the close of the regular session. Its affiliates, HLB Pharmaceutical and HLB Biostep, are also rising sharply in tandem, focusing attention on post-market stock price movements.

As of 5:43 p.m. on the 30th, HLB was trading at 43,950 won, up 4,250 won (+10.71%) from the previous day. During this time, a VI (Volatility Interruption) was triggered around 5:43 p.m. The fact that the stock is posting a double-digit gain with buying continuing to flow in even after the regular session has ended is drawing notice.

The market is focusing on whether the sharp price movements in the after-hours market will continue into the next trading day's regular session, and what trend will emerge in the November session. Issues related to the FDA are cited as matters that could affect the stock price going forward.
