EcoPro BM and EcoPro took the No. 1 and No. 2 spots in KOSDAQ market capitalization side by side in early trading on the 29th. Expectations of beneficiaries from growth in the robot market lifted their share prices. Alteogen, which had held the top market cap, slipped to third.
As of 9:26 a.m. that day, EcoPro BM was trading at 245,000 won, up 16,000 won (6.99%) from the previous session. EcoPro was up 0.77% at 169,900 won.
At the same time, EcoPro BM's market capitalization was 2.39613 trillion won, and EcoPro's was 2.30684 trillion won. Alteogen, down nearly 1% that day, was at 2.30610 trillion won, seesawing with EcoPro for the No. 2 market cap spot.
Shares of EcoPro BM and EcoPro rose as interest in solid-state batteries and related stocks grew alongside the robot market's expansion. In just the past week (22–28), EcoPro surged 77% and EcoPro BM jumped 43%.
Alteogen rose only 16% over the same period despite the overall strength of the KOSDAQ market. On the 21st, news that the royalty rate for sales of the Keytruda subcutaneous (SC) formulation, technology-transferred to Merck, was around 2%—lower than the securities industry's estimate of 4–5%—triggered a sharp drop in the stock.
With Alteogen planning a transfer listing to KOSPI in the first half of this year, some say passive funds tracking the KOSDAQ 150 index could flow into other large-cap KOSDAQ names such as EcoPro BM.
