Wat is meant by base value in stock exchange?

like it is said sensex falls or rise by so many points. wat does it mean.|||The BSE Sensex or Bombay Stock Exchange Sensitive Index is a value-weighted index composed of 30 stocks with the base April 1979 = 100. It consists of the 30 largest and most actively traded stocks, representative of various sectors, on the Bombay Stock Exchange. These companies account for around one-fifth of the market capitalization of the BSE.





The base value of the Sensex is 100 on April 1, 1979 and the base year of BSE-SENSEX is 1978-79.





At irregular intervals, the Bombay Stock Exchange (BSE) authorities review and modify its composition to make sure it reflects current market conditions.





The abbreviated form "Sensex" was coined by Deepak Mohoni around 1990 while writing market analysis columns for some of the business newspapers and magazines. It gained popularity over the next year or two.





The stock market has grown by over ten times from June 1990 to today. Using information from April 1979 onwards, the long-run rate of return on the BSE Sensex can be estimated to be 0.52% per week (continuously compounded) with a standard deviation of 3.67%. This translates to 27% per annum, which translates to roughly 18% per annum after compensating for inflation.
