Securities are all kinds of economic rights and interests certificates. Therefore, the securities market in a broad sense refers to all places where securities are issued and traded. In a narrow sense, the most active securities market refers to capital security market, currency securities market and commodity securities market. It is a place where stocks, bonds, commodity futures, stock futures, options, interest rate futures and other securities products are issued and traded.

The securities market is the product of the development of market economy to a certain stage, and it is a market to solve the contradiction between capital supply and demand and liquidity. The securities market realizes the connection between financing and investment by issuing and trading securities, which effectively solves the contradiction between supply and demand of funds and the adjustment of capital structure.

In the developed market economy, the securities market is an important part of a complete market system, which not only reflects and regulates the movement of monetary funds, but also has an important impact on the operation of the whole economy.
