[Disclosure] Jeju Semiconductor (080220) Designated as ‘Short-Term Overheated Stock’… 30-Minute Single-Price Trading Enforced for 3 Days Starting Jan 6

Source Fact: Financial Supervisory Service Electronic Disclosure System (DART) / 2026-01-05

Disclosure Type: Designation of Short-Term Overheated Stock (3-Trading-Day Single-Price Trading)

💡 3-Second Summary

Jeju Semiconductor’s stock has been hit with a “Short-Term Overheated Stock” label by the Korea Exchange following an aggressive short-term price surge. From January 6 to January 8, standard real-time continuous trading will be suspended, and the stock will be locked into a “Single-Price Trading” format where buy and sell orders are pooled and executed just once every 30 minutes.

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

• Target Stock: Jeju Semiconductor (Common Stock, KR7080220007)
• Designation Date: January 6, 2026
• Expiration Date: January 8, 2026 (Enforced for 3 consecutive trading days)
• Governing Provision: Article 23-2 of the KOSDAQ Market Operational Regulations and Article 28-2 of the Enforcement Rules.
• Market Action Details: Real-time continuous order matching is restricted during the designated window. A single-price call auction system matching orders at 30-minute intervals will be strictly applied.
• Extension Criteria: If the closing price on the expiration date (January 8) is 20% or higher than the closing price of the day prior to designation (January 5), the short-term overheated status will be extended for an additional 3 trading days (limited to a one-time extension).
• Release Date: If extension triggers are missed, the restriction will automatically lift on the next trading day following the expiration date (January 9, 2026), restoring normal real-time trading.

📈 2. [Expert View: Market Impact & Stock Price Analysis]

• Volume Contraction and Short-Term Momentum Cooling (Bearish/Correction Driver): Transitioning into a 30-minute single-price matching routine completely shuts out high-frequency day traders and ultra-short-term scalpers. The sudden disappearance of real-time order book mechanics inevitably triggers a severe contraction in trading volume, allowing short-term profit-taking orders to comfortably outweigh buying momentum.
• Historical Data Signals Intentional Consolidations: Statistically, a short-term overheated designation serves as a definitive speed bump engineered by regulators to stall parabolic rallies. Because market makers or dominant volume drivers face an additional 3-day extension penalty if the price climbs more than 20% on Day 3, they historically tend to keep prices capped or deliberately lower volumes, steering the asset into a mild technical or time correction.
• Long-Term Fundamentals Intact: This regulatory flag is not triggered by internal corporate deterioration, but is simply an exchange-mandated pacing measure to control extreme price velocity. If the underlying macro themes—such as the company’s expansion into On-Device AI chips and low-power memory (LPDDR)—remain robust, this 3-day window can be treated as a healthy consolidation phase to absorb overhead supply.

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

Well, boys, the engine on Jeju Semiconductor was running way too hot, and the regulators finally stepped in to pull us over! They’ve locked the stock into a 3-day single-price trading cage, telling us to cool down. Having to sit on our hands for 30 minutes just to see a single trade print means the high-speed day traders are officially forced into a vacation. Over on the retail message boards, it’s a total standoff: the diamond-hand bulls are saying, “Let the asset absorb the overhead supply for 3 days so we can gear up for Phase 2 of the mega rally,” while the short-term flippers are tweeting, “A 30-minute chokehold is unplayable, I’m dumping at tomorrow’s open.” Whether a rogue whale steps in on Day 3 to intentionally trigger the 20% extension badge or things settle down into a quiet pause, the ultimate high-stakes waiting game has officially begun!
