Answer:
The secondary market is the market in which securities are traded. This market no longer accumulates new financial resources for the issuer, but only reallocates resources among subsequent investors.
As a resale mechanism, it allows investors to freely buy and sell securities. In the absence of a secondary market or its weak organization, the subsequent resale of securities would be impossible or difficult, which would discourage investors from buying all or part of the securities. As a result, society would be left on the losing side, since many, especially the newest, undertakings would not receive the necessary financial support.
