Celltrion shares rose 1.47% despite the broader KOSPI market plunge. The upward momentum was driven by strong expectations following its record-high second-quarter earnings and an earnings surprise, alongside anticipation of future performance improvements and product line expansions [1][3][4][6]. This positive outlook prompted several brokerage firms to raise their target prices for the biopharmaceutical giant [2][4][6]. Additionally, simultaneous net buying from both foreign and institutional investors provided strong support for the stock price during trading [5].
