Korean Chip Equipment Stocks Drop 7% as Exchange Cuts Short Selling

South Korean chip equipment makers face a sharp pullback with declines exceeding 7%, as the Korea Exchange intervenes to curb overheated short-selling activity.

Shares of South Korean chip equipment manufacturers fell sharply on the 11th, reversing recent gains driven by artificial intelligence optimism. Hanmi Semiconductor, a leading player in the sector, traded at 233,500 won, marking a 7.71% drop from the previous session as of 10 a.m. This decline reflects broader market stress where volatile names are absorbing the heaviest losses amid worsening external conditions.

The broader market weakness was evident across key indices, with the KOSPI closing at 6,863.73, down 2.42%, and the KOSDAQ falling 1.77% to 822.14. The sell-off was not isolated to a single firm; peers such as Nexteen, PSK, Wonik IPS, and TES all registered declines between 5.23% and 6.97%, indicating a sector-wide correction rather than idiosyncratic company-specific issues.

Exchange Halts Short Sales to Stabilize Prices

The Korea Exchange designated Doosan Tesna, TCK, and LEENO Industrial as overheated short-selling stocks, immediately blocking short-sale transactions in both regular and after-hours trading for one day. This regulatory measure is triggered when short-selling turnover doubles, a condition met by several chip equipment firms. The intervention aims to prevent excessive price declines caused by concentrated short-selling activity during periods of high volatility.

According to market data cited by GN stocks/shares-fall, this designation is part of a broader effort to manage liquidity risks. By suspending short sales, the exchange seeks to dampen the negative feedback loop where falling prices attract more short sellers, further depressing valuations. This step underscores the regulatory focus on maintaining orderly trading conditions in highly speculative sectors.

AI Rally Faces Macro Headwinds and Profit Taking

The recent pullback follows a steep uptrend fueled by expectations of an AI-driven boom. HPSP, a front-end equipment maker, had surged 48.88% in the past month, while Jusung Engineering gained 45.88%. Sector-linked instruments also posted strong returns, with the KIWOOM K-Semiconductor North America Supply Chain ETF rising 32.72% and the KODEX AI Semiconductor Core Equipment ETF gaining 31.29% over the same period.

However, deteriorating macroeconomic conditions are now outweighing these growth narratives. Rising oil prices and interest rates, exacerbated by the ongoing Middle East conflict, have dampened global investor sentiment. With domestic and overseas markets expected to remain subdued, investors are prioritizing risk reduction, leading to concentrated selling in stocks that have exhibited the highest recent volatility.

Market Sentiment Shifts Toward Risk Aversion

The decline in chip equipment stocks is directly tied to the broader macro environment, where rising borrowing costs and geopolitical tensions are eroding risk appetite. As the likelihood of a prolonged subdued market increases, capital is flowing out of high-beta technology sectors. This shift highlights the sensitivity of equipment makers to external economic shocks, particularly when their valuation premiums are heavily predicated on optimistic future growth assumptions.

The concurrent rise in oil and interest rates creates a dual headwind for the sector, increasing operational costs for end-users and reducing the present value of future cash flows. Consequently, the market is repricing these equities to reflect higher risk premiums. The sharp drop in Hanmi Semiconductor and its peers serves as a barometer for this changing sentiment, signaling a period of consolidation and reassessment for the Korean semiconductor supply chain.
