The Bombay Stock Exchange (BSE) and the S&P-Dow Jones Indices announced a strategic partnership on Tuesday that would see the Sensex and indexes such as the BSE 200 and BSE 100 co-branded as S&P.

The move is effective from Tuesday and would allow the BSE and the S&P Dow Jones to calculate, disseminate, and license the widely followed suite of BSE indexes.
