Lockups on a combined 109.23 million shares at 52 companies listed on South Korea’s KOSPI and KOSDAQ markets will expire in November, potentially increasing selling pressure and price volatility. KOSDAQ-listed companies account for 106.52 million shares across 48 firms, while four KOSPI companies account for 2.71 million shares. The Korea Securities Depository said the largest releases relative to outstanding stock involve Cochip, Nobrand and Synap Soft. Cochip will release 5,665,543 shares, equal to 65% of its outstanding stock, on Nov. 7. Nobrand will release 8,436,424 shares, or 50%, on Nov. 23, while Synap Soft will release 2,419,271 shares, or 48%, on Nov. 19.

Mandatory holding registration is an electronic system that prevents largest shareholders or institutions from selling acquired shares for a specified period, helping protect ordinary investors. Market participants recommend reviewing release dates and freely tradable supply because early investors or major shareholders may take profits after restrictions end.
