📊 1. [Key Disclosure Content & Market Restriction Figures]

• Subject Stock: Jusung Engineering (Ticker: 036930)
• Designation & Effective Date: January 9, 2026 (Friday)
• Governing Regulations: Article 9-2 of the KOSDAQ Market Operational Regulations and Article 8-5 of the Enforcement Rules.
• Scope of Restriction: Short-selling transactions are completely prohibited in both the regular trading session and after-hours markets for one day on the designation date. (Short-selling resumes on the following trading day).
• Extension Conditional Clause: If the closing share price drops by -5% or more on the day of the short-selling ban (January 9), the short-selling prohibition period will be consecutively extended.
• Permitted Statutory Exceptions: Short-selling quotes are exceptionally allowed strictly for liquidity provision quotes (LP), market-making quotes, hedging transactions for ELW, ETF, and ETN products, and hedging purposes intended for derivatives market-making.
• ※ If trading of the subject stock is already suspended on the designation date, no separate additional administrative measures regarding short-selling will take effect.

📈 2. [Expert Insight: Impact on Share Price]

• Temporary Brake on Downward Velocity & Potential Long Bids: The designation as a short-selling overheated stock implies that short-selling transaction volume and its total weight have aggressively spiked recently. By legally freezing the expansion of new short positions for a day, the market structure eliminates immediate downward artificial momentum. This setup historically triggers technical rebounds or short-term long bids capitalizing on the temporary supply-demand vacuum.
• Latent Downside Risk & Post-Ban Overhang Pressures: However, investors must recognize that the designation itself acts as a fundamental confirmation that structural negative sentiment (including broader microchip sector cyclical limits or near-term macro headwind metrics) is heavily active. The conditional rule stating that a -5% or sharper drop on January 9 will trigger an extension sets up an intense institutional battleground. Since short-selling is authorized to resume on the following session, the threat of accumulated short interest being unleashed as an equity overhang remains unmitigated.

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

Market participants tracking Jusung Engineering should avoid misinterpreting this regulatory short-selling freeze as a definitive macro buy signal. The Korea Exchange’s decision to deploy this mechanical intervention is a stark alarm bell confirming that the structural momentum driving short positions was reaching critical velocity. While short covering might fuel a temporary intraday bounce on January 9, the stock faces a critical testing ground where a closing dip past -5% alters the entire timeline. Furthermore, under-the-radar short exemptions for institutional liquidity providers (LPs) remain active, and the massive dam of short interest will unlock the very next day. Chasing immediate momentum here carries significant risks; safeguarding capital through strict downside support verification should take absolute priority.
