Synopsis A stock (or share) market deals mainly in corporate securities. The securities are chiefly in the form of equity shares and debentures. The function of the stock market is two-fold: (a) to arrange for the raising of new capital [primary market function] and (b) to provide liquidity to existing securities [secondary market function].
