Understanding the Stock Index
An index could be a variety that measures the modification in an exceedingly set of values over an amount of your time. A stock index represents the modification in price of a group of stocks that represent the index. More specifically, a stock index or stock market index number is that the current relative price of a weighted average of the prices of a pre-defined group of equities. A stock exchange index is formed by choosing a gaggle of stocks that square measure representative of the whole market or a specific sector or section of the market. It's calculated with regard to a base amount and a base index price. The start value or base of the index is typically set to variety like one hundred or one thousand. For Example, National Stock Exchange Index NIFTY base points set to 1000 on construction date of November 3rd, 1995.
The main advantages of Stock market indices are:
1. As a barometer for market behaviour,
2. As a benchmark for portfolio performance,
3. As an underlying in derivative instruments like Index futures, Index options, and
4. In passive fund management by index funds/ETFs
A stock index or stock market index is a measurement of a section of the stock market. It is computed from the prices of selected stocks (typically a weighted average). It is a tool used by investors and financial managers to describe the market, and to compare the return on specific investments.
Two of the primary criteria of an index are that it is investable and transparent, the method of its construction should be clear. Many mutual funds and exchange-traded funds attempt to "track" an index (see index fund) with varying degrees of success. The difference between an index fund's performance and the index is called tracking error.
