Company’s that Comprise the BSE Sensex

The BSE Sensex or Sensex as it is more commonly called is one of two premier Indices in India. It is the index that depicts the movement of the Bombay Stock Exchange or BSE. In one of our earlier posts, we had taken a look at what the BSE is. To view that post "click here".

In this post, we are going to take a look at the 30 company’s that comprise this Sensex Index.

To Recap:
BSE Sensex is the weighted average of the price movement of the 30 largest company’s that are listed in the Bombay Stock Exchange. This list of company’s may change from time to time and the Exchange will always release the news of replacement of any company in the Sensex to the public beforehand.
Below is the list of 30 company’s that comprise the BSE Sensex along with their Industry and Weightage.

Note: A company with 1% weightage will have to increase twice as much as one with a 2% weightage in order to move the index up or down by the same number.

The list above is ordered Alphabetically based on the company name :-). Also, the list above is correct as of 15th January 2012. If there are any updates to the Index, I will try to update this post accordingly...


  1. Hi Anand,

    could you please explain this "A company with 1% weightage will have to increase twice as much as one with a 2% weightage in order to move the index up or down by the same number. " in numerals .


  2. Hi Srini,
    Explaining the index calculation in one comment is practically impossible. But, for the sake of a simple example, let us say Company A has a 1% weightage in the index and Company B has a 2% weightage and both are trading at Rs. 100/- each.

    So, a Rs. 2 movement in the price of Stock A and a Rs. 1 movement in the price of Stock B will have the same effect on the index.

    Hope this clarifies.


  3. Fine. Very clear.
