How increase and decrease in sensex is calculated?-BSE-NSE
I want to know how the decrease and increase in Sensex happens.
A lot of time i see that sensex is down but many companies have their shares on rise.
Does movement in Sensex affects every share in the market?
For introductry prupose read the article Stock Markets-a premium investment option.
Sensex is the index in BSE. It does not represent overall market but the movement in share prices of major shares only.
Sensex consider 30 companies to indicate the movement in market. These 3o companies are not fixed, but decided from time to time by BSE.
There is a little complicate formula that is used to calculate the movement in Sensex or any stock market index.
