Even as IPOs have increased for the year, investors and other financial experts track the subsequent success of companies after IPO day. Snap, Inc., for example, dropped dramatically from its opening day price soon after its IPO.

An IPO usually raises a great deal of cash for a company. Companies usually decide to have an IPO when early investors are looking to cash-out of their investment, or simply as a strategic way to diversify risk and ownership.
