The most important point to be noted is Securities and Exchange Commission or any other regulatory body did not make any mandatory rules regarding the lock-up periods. The company which is going to be public or which is required by investment banker has self-imposed it.

The main goal of a lock-up period is only to maintain high stock prices once the company goes public and also to stop flooding which is done by large investors which depress the stock prices in the initial stage. Compared to the public, insiders of companies own a high percentage of stock shares disproportionately. The consequence of this would impact the share price of the company drastically when it goes public.

To avoid this, a lock-up period is followed for at least 6 months. There is even more advantage of this lock period. It gives you more time to investigate the performance of stock. It may vary from the initial stage to the end of the lock-up period and if it does not meet your expectations, it also may be worth buying something else.

But if the stock price does not vary and remains the same till the end of the lock-up period, it would be a sound investment. A scenario may also occur if the earning season coincides with the lock-up period, where the insiders of the company can still be prevented from selling the shares even after the expiration of the lock-up period. But this happens only when the insider can access the non-public information and the material.


People who are doing small investments should also consider the pros and cons significantly before buying the IPO stock. Though Purchasing IPO stocks contains risk, it may be significant. And the most important point to consider is, if the first-day pop of an IPO is good, expecting the same profit until the last is worthless.

Most of the companies enter into IPO without having proper knowledge which results in huge loss. Often New IPOs have less history compared to older ones, which may be lead to difficulty in assessing it. This affects the new individual investors the most. It is always good to limit your respective position on any individual stock to a few percent of your holdings.
