While cooling solutions are cited as promising stocks domestically and abroad as key technologies for improving the performance of high-performance AI (artificial intelligence) semiconductors, the stock prices of KOSDAQ-listed companies presenting these as business models have been under correction since the second quarter.
On the 4th, in the Korea Exchange (KRX) KOSPI market, GST, a stock related to data center thermal management businesses such as immersion cooling, closed at 43,000 won, up 4.5 percent from the previous trading day. Data center immersion cooling solution provider KNSol also closed up 0.59 percent at 8,580 won, marking its first closing gain in seven trading days.
Both companies share commonalities as representative KOSDAQ-listed firms possessing immersion cooling technology capable of managing high-performance AI heat generation, and both have seen their stock charts follow a downward trend after recording 52-week highs in the second quarter.
It is projected that power consumption for data centers required for high-performance AI will reach three to five times that of general data centers, not only in Korea but globally. Consequently, cooling technologies capable of resolving the surge in AI computations and heat generation resulting from data center advancement are regarded as key elements within the related value chain.
However, despite the potential for market expansion, related stocks have failed to rebound since their peak in the second quarter. Capital market experts point out that while these KOSDAQ cooling-related stocks possess the necessary technology, the entry barriers themselves are not high.
Kang Min-gu, a researcher at IBK Investment & Securities, noted that while the performance of these companies is improving, "it is difficult to ignore the possibility that new competitors such as startups will enter the market," adding that "there is a need for more time to prove whether they can sustainably maintain good performance."
