Sensex is a stock market index that was launched by BSE (Bombay Stock Exchange) in 1986. It assesses fluctuations in stock prices of 30 biggest companies in terms of market value, turn over, profit, etc. The value of Sensex is calculated on a per minute basis.
In simple terms, if the value of Sensex is going up, then the stock price of most companies on BSE will go up and if the value of Sensex is going down, then stock price of most companies will go down.
Sensex was introduced to give direction to buyers and sellers in terms of whether the market is going up or down. The term Sensex was coined by a stock market analyst Mr. Deepak Mohoni.
Companies included under Sensex are selected by S&P BSE Index Committee based on the following criteria:
– The company has to be listed under BSE in India.
- It must consist of large or mega-cap stocks.
- It has to be relatively liquid.
- The earnings of the company must come from its core activities.
- The company must contribute to keep the sector balanced with the country’s equity market.
