The support that brokerage firms and market makers and their customers provide to a public offering that has resulted from a reverse merger or self-filing. It constitutes secondary trading on an exchange once an issuer has finalized its
initial public offering (IPO), or otherwise had its shares listed. Technically speaking, aftermarket support is the proactive process of creating marketability, visibility and, above all, liquidity in a publicly traded stock. A company would need to exert active effort by its own and/or with the help of its investor relations firm. Liquidity is only created when a stock is widely held, actively traded, is followed by equity analyst (stock followers).
Strong aftermarket support is key for the success of a public offering.
