Melcon, a company specializing in environmental control equipment for semiconductor processes, is experiencing a surge of over 40% on its first day of trading on the KOSDAQ. Early in the session, the stock price soared to more than double its initial public offering (IPO) price, attracting significant investor interest.


As of 2:12 PM on October 15, Melcon's shares were trading at 17,850 won, up 45.12% (5,550 won) from the IPO price of 12,300 won, according to the Korea Exchange.


Shortly after the market opened, Melcon's stock rose as much as 134.15%, reaching 28,800 won, before pulling back slightly but remaining well above the IPO price.


Founded in 2003, Melcon develops and manufactures environmental control equipment necessary for semiconductor manufacturing processes. The company supplies equipment that maintains consistent temperature, humidity, and air cleanliness within semiconductor manufacturing equipment.


Maintaining a precise process environment is crucial in semiconductor manufacturing, making the role of temperature and humidity control equipment significant. Melcon focuses on providing reliable equipment for managing these process environments.


Previously, Melcon set its IPO price at the upper end of its desired range, which was between 10,700 and 12,300 won. The strong performance of its stock on the first day of trading indicates continued market interest.


In contrast, Jincostec, which also debuted on the KOSDAQ today, is experiencing a downward trend in its stock price. At the same time, Jincostec's shares were trading at 16,130 won, down 32.37% (7,720 won) from its IPO price of 23,850 won.


Jincostec is an original design manufacturer (ODM) that produces cosmetics based on hydrogel materials.


While both companies entered the KOSDAQ on the same day, Melcon's stock is significantly outperforming its IPO price, whereas Jincostec has seen a decline of over 30%, reflecting contrasting market trends.
