Source Fact: Financial Supervisory Service Electronic Disclosure System (DART) / 2025.04.07

Disclosure Type: Designation of Short-Selling Overheated Stock (Short-Selling Ban Applied)

💡 3-Second Summary

Due to an abnormal surge in aggressive short-selling transactions, the Korea Exchange (KRX) has officially designated HANMI Semiconductor as a “Short-Selling Overheated Stock.” Consequently, all short-selling activities will be strictly banned during the regular and after-hours markets on April 8. If the stock price plunges by 5% or more on the day of the ban, the restriction period will be automatically extended.

📊 1. [Key Disclosure Content & Summary of Major Figures]

• Target Stock: HANMI Semiconductor Common Stock (Standard Ticker: KR7042700005 / Short Ticker: 042700)
• Regulatory Measures: Comprehensive short-selling ban across regular and after-hours trading sessions for exactly one day on April 8, 2025 (Short transactions will resume normal execution starting April 9).
• Ban Extension Criteria: If the closing stock price declines by -5% or more on the day of the ban, the temporary short-selling restriction will be regulatory extended.
• Statutory Ground: Article 17 of the KOSPI Market Business Regulation & Article 24-3 of the Enforcement Rules.
• Exempted Transactions (Exceptions): Liquidity Provider (LP) and Market Maker (MM) quotes, hedging transactions for ELW·ETF·ETN products, and hedging orders for derivatives market-making purposes remain exceptionally permitted.

📈 2. [Expert View: Analysis of Impact on Stock Price]

• Evidence of Peak Short Exposure Priming Short-Covering (Short-Term Positive Trigger): The designation as a “short-selling overheated stock” is an ironic contrarian indicator showing that institutional short bets against HANMI have reached a temporary peak. By cutting off the most volatile downward pressure tool for April 8, the stock is highly likely to secure near-term breathing room. If the price edges upward, it could spark a “Short Covering” rally where short-sellers are forced to buy back shares to limit losses, boosting immediate demand.
• A Litmus Test for the Absolute Technical Floor: The street will focus heavily on whether the price holds the -5% threshold during the ban day. If the stock drops over 5% even without the aid of fresh short-selling entries, it indicates structural panic selling from long holders rather than synthetic manipulation, which could delay recovery. Conversely, if the stock holds firm or bounces back, April 8 will be marked as a firm mid-term technical bottom, restoring healthier buy-side liquidity.

📝 Editor’s Comment (by K-STOCK Editor)

Despite executing major capital adjustments like share retirements and formalizing an aggressive 2 trillion KRW revenue path, even a tech titan like HANMI Semiconductor could not escape the crosshairs of ruthless hedge fund short-selling raids. This regulatory designation proves that short sellers have thrown everything they have to suppress the stock’s multiple. While cutting off fresh short transactions on April 8 provides immediate structural relief, institutional long blocks should stay sharp, as exceptional liquidity provider (LP) hedging allocations can still bypass the ban. Rather than executing emotional panic sales, the prudent move is to calmly analyze the closing print to see if HANMI can successfully defend the -5% support zone, potentially laying down the groundwork for a massive short-squeeze.
