To properly understand the concept of Sensex it is very much important for the people to have a clear-cut understanding of the Indian stock exchanges in the very beginning. The Bombay Stock Exchange is the Indian stock exchange which is located in Dalal Street Mumbai Maharashtra. It was established in the year 1875 and is the oldest stock exchange in Asia. This is the world’s fastest stock exchange with a median trade speed of 6 microseconds and more than 5500 companies are publicly listed on this particular stock exchange. Thousands of companies are listed on the stock exchange and hence it becomes very much hard to track every single stock to evaluate the market performance at a single point of time which is the main reason that the companies need to depend upon a market index and index is always calculated from the prices of selected stocks.

  3. The market indexes are utilised for sorting and comparison of different kinds of companies because such indices will act as an underlying for index funds, options, index features and several other kinds of things.
  4. It will be used in passive fund management by the index funds and the index will also give a proper comparison of return on investment in the stock markets in comparison to the asset classes like gold or debt.
