On July 16, the KOSDAQ market experienced a sharp decline, with shares of biotech firm Peptoron (087010) also closing down more than 8%. The stock has recently exhibited extreme volatility, drawing investors' attention to its price trajectory following the Constitution Day holiday.

In the regular trading session, Peptoron finished at 119,200 won, down 10,800 won (8.31%) from the previous trading day. On the same day, the KOSDAQ index also closed at 791.84, down 37.59 points (4.53%) from the prior session. The significant contraction in overall market sentiment and an expanding shift away from risk assets are interpreted as the primary factors weighing on Peptoron's share price.

Peptoron's stock has been swinging wildly in the short term. After hitting the lower limit amid a sharp sell-off on July 10, it briefly fell below the 100,000-won level during intraday trading on July 14. However, it rebounded with double-digit gains on July 15, drawing attention, before returning to a steep decline on July 16, continuing its highly volatile trend.

Amid this repeated cycle of gains and losses, investors are closely monitoring short-term supply and demand dynamics as well as market sentiment. With domestic markets closed on July 17 for Constitution Day, market attention is expected to focus on U.S. stock market trends and shifts in global investor sentiment during the holiday period.
