Investopedia explains 'Lock-Up Agreement'


Underwriters will have company executives, managers, employees and venture capitalists sign lock-up agreements to ensure an element of stability in the stock's price in the first few months of trading. When lock-ups expire, restricted people are permitted to sell their stock, which sometimes (if these insiders are looking to sell their stock) results in a drastic drop in share price due to the huge increase in supply of stock.
