What is Lock-Up Period

A lock-up period is a window of time when investors in a hedge fund or another closely held investment vehicle are not allowed to redeem or sell shares. The lock-up period helps portfolio managers avoid liquidity problems while capital is put to work in sometimes illiquid investments.

The initial public offering (IPO) lock-up is a typical lock-up period in the equities market used for newly issued public shares. It typically lasts anywhere from 90 to 180 days after the first day of trading so that fund managers can keep a lower amount of cash on hand.

BREAKING DOWN Lock-Up Period

The lock-up period for hedge funds corresponds with the underlying investments of each fund. For example, a long/short fund invested mostly in liquid stocks may have a three-month lock-up period. Because event-driven or distressed hedge funds often invest in more thinly traded securities like loans or other debt, they tend to have prolonged lock-up periods. Still, other hedge funds may have no lock-up period at all depending on the structure of the fund's investments.

When the lock-up period ends, investors may redeem their shares according to a set schedule, often quarterly. They normally must give a 30- to 90-day notice so that the fund manager may liquidate underlying securities which allow for payment of the investors.

Importance of a Lock-Up Period for a Hedge Fund

During the lock-up period, a hedge fund manager may invest in securities according to the fund’s goals without concern for share redemption. The manager has time for building strong positions in various assets and maximizing potential gains while keeping less cash on hand. In the absence of a lock-up period and scheduled redemption schedule, a hedge fund manager would need a great amount of cash or cash equivalents available at all times. Less money would be invested, and returns may be lower. Also, because each investor’s lock-up period varies by his personal investment date, massive liquidation cannot take place for any given fund at one time.

Lock-Up Period for an IPO

The lock-up period for newly issued public shares of a company helps stabilize the stock price after it enters the market. When the stock’s price and demand are up, the company brings in more money. If business insiders sold their shares to the public, it would appear the business is not worth investing in, and stock prices and demand would go down.

When a private company begins the process to go public, key employees are paid little in exchange shares of company stock. Because receiving stock is the equivalent of receiving a paycheck, many of these employees want to cash in their shares as quickly as possible after the company becomes publicly traded. The lock-up period prevents stock from being sold immediately after the IPO when share prices may be exaggerated and likely to drop after the company’s IPO.

Example of a Lock-Up Period

In March 2015, Alibaba Group Holding Inc.’s six-month lock-up period ended. Company insiders owning 437 million shares, approximately 18% of the outstanding shares, were allowed to sell their stock. Many investors were more concerned with receiving profits than with their cost basis. As a result, the stock price decreased dramatically.
