CASE - 4 Indian Stock Market: Does it Explain Perfect Competition?
The stock market is one of
the most important sources for corporates to raise capital. A stock
exchange provides a market place, whether real or virtual, to facilitate the exchange of securities
between buyers and sellers. It provides a real time trading information on the listed securities,
facilitating price discovery.
Participants in the stock market range from small individual investors to large traders, who can be
based anywhere in the world. Their orders usually end up with a professional at a stock exchange, who
executes the order. Some exchanges are physical locations where transactions are carried out on a
trading floor. The other type of exchange is of a virtual kind, composed of a network of computers and
trades are made electronically via traders.
By design a stock exchange resembles perfect competition. Large number of rational profit
maximisers actively competing with each other, trying to predict future market value of individual
securities comprises the main feature of any stock market. Important current information is almost freely
available to all participants. Price of individual security is determined by market forces and reflects the
effect of events that have already occurred and are expected to occur. In the short run it is not easy for
a market player to either exit or enter; one cannot exit and enter for few days in those stocks which are
under no delivery. For example Tata Steel was in no delivery from 29/10/07 to 02/11/07. Similarly one
cannot enter or exit on those stocks which are in upper or lower circuit for few regular trading sessions.
Therefore a player has to depend wholly on market price for its profit maximizing output (in this case
stock of securities). In the long run players may exit the market if they are not able to earn profit, but at
the same time new investors are attracted by rise in market price.
As on 01/11/07 total market capital at Bombay Stock Exchange (BSE) is $1589.43 billion (source:
Business Standard, 1/11/2007); out of this individual investors account for only $100bn. In spite of the
fact that individual investors exist in a very large number, their capital base is less than 7% of total
market capital; rest of capital is owned by foreign institutional investor and domestic institutional
investors (FIIs and DIIs), which are very small in number. Average capital owned by a single large
player is huge in comparison to small investor. This situation seems to have prompted Dr Dash of BSE
to comment 'The stock market activity is increasingly becoming more centralised, concentrated and non
competitive, serving interest of big players only." Table 2 shows the impact of change in FII on National
Stock Exchange movement during three different time periods.

By design, an Indian Stock Market resembles perfect competition, not as a complete description (for
no markets may satisfy all requirements of the model) but as an approximation.
