Equal weighted index and Value weighted index.

Most of the stock market indices used in practice are of two types: equal weighted index and value weighted index.

An equal weighted index reflects the simple arithmetic average of the price relatives of the sample shares in a certain year (or month or week or on a particular day) with reference to a base year. A value weighted index reflects the aggregate market capitalization of the sample shares in a certain year (or month or week or on a particular day) in relation to a base year. Bombay Stock exchange Sensitive Index (popularly called Sensex) and S&P CNX Nifty Index (popularly called Nifty) are value-weighted indices.

Further the Ministry of Finance, Government of India, has transferred most of the powers under the Securities Contracts (Regulations) Act to SEBI.

SEBI has taken a number of steps in the last few years to reform the Indian capital market. While SEBI has done a great deal, it has a long way to go in accomplishing its mission. It has to address challenges like the preponderance of speculative trading and market abuses.
