On the 29th, when both the KOSPI and KOSDAQ declined, Celltrion demonstrated a strong upward trend, recording gains on both the Korea Exchange (KRX) regular market and the alternative trading platform NXT.

In the KRX regular market, Celltrion closed 1.47% higher compared to the previous trading day, while on the NXT market, the gain expanded to 2.71%. Notably, on NXT, where trading continues even after the KRX regular market closes, the gains grew larger, sustaining a buy-dominant trend through the latter half of the session.

This signals that buying interest flowed into Celltrion even as investor sentiment shrank amid a broad market decline, with both the KOSPI and KOSDAQ closing lower on the day.

However, it is difficult to draw definitive conclusions about the stock's direction by simply comparing the rate of change between the two markets. KRX and NXT differ in trading hours, trading volume, and participant composition; with NXT's trading volume lower than KRX's, even a limited number of orders can result in larger price swings.

Going forward, Celltrion's earnings trajectory, expansion of biosimilar product sales, and changes in overseas market share are expected to emerge as key focal points. Additionally, it remains to be seen how the price gap between KRX and NXT will be reflected in the regular market opening price on the next trading day.
