A stock market index is a statistical tool that tracks financial market changes. The indices are performance indicators that reflect the performance of a certain market segment or the market as a whole. A stock market index is created by selecting securities from similar companies or those that meet a specific set of criteria. These shares have previously been listed on the exchange and traded. Share market indices can be created using a variety of variables, such as industry, segment, or market capitalization.
Each stock market index monitors the price movement and performance of the stocks that make up the index. This simply indicates that the success of a stock market index is directly proportional to the performance of its component stocks. In layman terms, if the prices of the stocks in an index rise, the index as a whole rises as well.
Types of Stock Market Index
a) Sectoral Index.
In the Indian context, two major stock market indexes are utilized to evaluate markets: the Sensex and Nifty. Indian investors can follow the changes in these index values over time and use them as a benchmark to assess their own portfolio returns.
Both the BSE and the NSE offer excellent indicators for evaluating companies in a certain sector. A significant example is the Nifty PSU Bank Index, which contains stocks for all listed public sector banks.
Benchmark Index
The Nifty 50 index, which includes the top 50 best-performing equities, and the BSE Sensex index, which includes the top 30 best-performing stocks, serve as indicators for the NSE and the Bombay Stock Exchange, respectively. This group of equities is regarded as a benchmark index since they use the highest standards to regulate the companies they choose. As a result, they are regarded as the most trustworthy source of knowledge regarding how markets function in general.
Market Cap Index
Few indices rank companies based on their market capitalization. Market capitalization is the stock exchange market value of any publicly traded company. For example, the Securities Exchange Board of India (SEBI) defines indices like S&P BSE and NSE small cap 50 to be comprised of companies with a lower market capitalization.
Formation of an Index
A stock market index is formed by grouping equities with similar market capitalizations, firm sizes, or industries. The index is then calculated depending on the stocks selected. Each stock, however, will have its own price, and the price range will fluctuate from one to the next. As a result, summing the prices of all stocks does not yield the index value.
Stock weighting comes into play. Each stock in the index is assigned a weightage based on its current market price or market capitalization. The weight determines the effect of stock price variations on the index value.
Market Capitalization Weightage
Market capitalization is a company’s total market value on the stock exchange. It is calculated by multiplying the total number of outstanding shares issued by the company by the stock price. In contrast, a market-cap-weighted index selects stocks based on their market capitalization in relation to the index’s overall market capitalization.
Price Weightage
This technique calculates the index value using market capitalization rather than the company’s stock price. As a result, shares with higher prices are given a higher weightage in the index than those with lower prices.
