Lock-up Period

The lock-up period is a predetermined time frame during which investors or insiders are restricted from selling their shares after an initial public offering (IPO) or another significant financial event. The purpose of the lock-up period is to prevent large amounts of shares from flooding the market immediately after the IPO, which could cause the stock price to drop. Lock-up periods typically last for 90 to 180 days, after which investors are free to sell their shares.

Example

After a company’s IPO, insiders such as executives and early investors are subject to a 180-day lock-up period, during which they cannot sell their shares to prevent sudden stock price volatility.
