Alteogen (196170) continued its decline in after-hours trading (NXT) following the regular market close, dropping to the low 300,000 won range, a psychological support level. Investors are closely watching whether the stock can defend the 300,000 won level.

In the regular session on the 13th, Alteogen closed at 316,500 won, down 7,500 won (2.31%) from the previous trading day. However, in the post-market NXT aftermarket, the decline deepened, with the price falling to 305,000 won as of 6:07 PM.

As a result, defending the 300,000 won level has emerged as a key short-term focal point. The KOSDAQ index closed at 799.36 on the day, plunging 38.07 points (4.55%) from the previous trading day and falling below the 800 level. Alteogen is analyzed to have been affected by broader market weakness as selling pressure spread across growth stocks and the biotech sector in general.

The defense of the 300,000 won level is expected to be a critical inflection point for the stock's future price trajectory. Attention is focused on whether buying interest will flow in on the next trading day and whether investor sentiment in the KOSDAQ market will recover. Meanwhile, developments related to the recent escalation of geopolitical risks between the United States and Iran also warrant monitoring.
