Source Fact: Korea Exchange KOSDAQ Market Division / 2026-05-28
Disclosure Type: Extension of Short Sale Overheated Stock Designation (Short Selling Ban Extended)
💡 3-Second Summary
The Korea Exchange has extended the short selling ban on HPSP for another trading day as the abnormal shorting surge remains uncooled. Consequently, short selling will continue to be strictly prohibited across both regular and after-hours sessions on Friday, May 29, 2026. If the stock slides by 5% or more on the day, the restriction will trigger another automatic extension.
📊 1. [Summary of Core Disclosure Content and Major Figures]
- Target Security: HPSP (Common Stock, KR7403870009)
- Extended Short Selling Ban Date: May 29, 2026 (For 1 day, covering all regular and after-hours trading blocks)
- Further Extension Clause: If the stock price falls by -5% or more on the extended ban date (May 29), the short-selling restriction will automatically chain into another extension.
- Exemptions: Short selling remains exceptionally permitted for liquidity providing (LP) quotes, market-making operations, and regulatory hedge positioning for ELW/ETF/ETN products.
- Governing Rules: Article 9-2 of the KOSDAQ Market Operational Regulations
📈 2. [Expert View: Analysis of the Impact on Share Price]
- Defensive Cushion Retained & Groundwork for Continued Short Squeeze: An “extension” of a short sale ban indicates that underlying short interest volatility during the initial block failed to fall within safe regulatory parameters. Keeping the bears’ primary price-suppression tool locked up right before the weekend gives HPSP strong short-term programmatic support. If bearish traders feel the heat of financing costs and scramble to buy back shares to trim exposure (short covering), the upward technical momentum could see high-velocity compounding.
- Pre-Weekend Order Book Friction: While the defensive -5% extension rule provides a strong technical floor, trading desks will see fierce cross-currents as participants price in the potential lifting of the ban for the following week. This regulatory event represents a mechanical tug-of-war rather than a structural reassessment of HPSP’s high-pressure annealing technology. Keeping a close eye on true institutional and foreign net inflows during this restriction window is paramount to filtering real demand from speculative covering noise.
📝 Editor’s Comment (by K-STOCK Editor)
The absolute war between the bulls and the short sellers on HPSP just got dialed up to eleven! The bears tried to aggressively hammer the tape, but the KRX referees just pointed at the whistle and extended their red card through Friday, May 29. This leaves the heavy short anvil locked in handcuffs for another entire session, giving the bulls the perfect launchpad to squeeze the bears right before the weekend. With artificial selling volume forced off the board, a strong wave of panic buying from short-trapped positions trying to cover could send this thing into orbit. Keep your eyes on that -5% trigger—if the price slides past that mark, the ban rolls over again, turning this into a psychological nightmare for the shorts. Friday’s opening tape is going to be absolute fireworks!
