Sterlite Industries and Tata Power Company were included in the place of Ambuja Cements, a unit of Zurich-based Holcim, and domestic pharma major Cipla respectively.
The index committee of the BSE in its meeting held on June 13 decided to revise the composition of Sensex, BSE-100, BSE-200 and BSE-500 indices.
The revision in the Sensex will be effective from July 28, while revisions in the BSE-100, BSE-200 and BSE-500 will become effective from June 23, BSE said in a statement.
This would be Tata Power's re-introduction into the most popular index of the BSE. Earlier, it was replaced by Anil Ambani-controlled Reliance Communications and last traded as a Sensex stock on June 9, 2006.
The full market capitalisation of Cipla stood at 16,424.17 crore with an weightage of 1.03 per cent, while Ambuja Cements had an weightage of 0.68 per cent with a market cap of 12,941.12 crore.
