Main Page | See live article | Alphabetical index The aftermarket is the financial market for trading of already issued securities. In the secondary market, securities are sold by and transferred from one investor to another. It is therefore important that the secondary market be highly liquid and transparent. The eligibility of shares and bonds for trading in the secondary market is regulated through financial supervisory authorities and the rules of the market place in question, which could be a stock exchange.
