Lockup period

Period during which a share may not be sold

The term lock-up period refers to the period during which existing shareholders, usually with large stakes in a company, commit not to sell any shares from their holdings after an IPO. In Germany, a lock-up period of between 6 and 18 months is frequently used. It serves to protect new shareholders from falling prices.
