1. What Happened?: Protina’s Investment Warning

Protina received an investment warning on September 16, 2025, primarily due to a recent surge in its stock price. The price jumped approximately 35% from 24,600 KRW on September 4th to 33,300 KRW on September 16th. This was accompanied by a significant increase in trading volume, suggesting speculative demand. The surge and subsequent decline in foreign ownership warrants particular attention.

2. Why?: The Reasons Behind the Surge and the Investment Warning

Protina has been recognized for its growth potential in the drug and antibody development market, driven by its innovative SPID Platform technology. However, its continued losses due to high R&D expenses require careful consideration from investors. The investment warning is likely a technical correction in response to the rapid price surge rather than a reflection of worsening fundamentals. However, the potential for negative investor sentiment and increased foreign selling pressure should not be ignored.

3. What’s Next?: Future Outlook and Investment Strategies

In the short term, increased price volatility and negative investor sentiment could put downward pressure on the stock. The continued selling by foreign investors will be a key factor to watch. In the medium to long term, Protina’s fundamentals, particularly its ability to improve profitability, will determine the stock’s direction.

4. What Should Investors Do?: Action Plan

  • Short-term investors: Proceed with caution given the potential for increased volatility. Avoid chasing the stock and consider a wait-and-see approach. Current holders should monitor the timing of the warning lift and closely watch foreign selling trends.
  • Long-term investors: If you are confident in Protina’s technological competitiveness and long-term growth potential, you may choose to maintain your investment with a long-term perspective. However, it is crucial to continuously monitor the company’s progress towards profitability.

5. Protina’s Response: Strengthening IR Activities

Protina needs to strengthen its communication with the market through proactive investor relations activities, clearly communicating its fundamentals and future growth strategies to alleviate investor concerns.
