On July 28th 2008, Sterlite Industries (SLT) will be added to India's key Bombay Stock Exchange Index, The Sensex 30. Sterlite is India's largest publicly traded COPPER and ZINC producer.
FYI, The Sensex is basically India's equivalent of the U.S.'s Dow Jones Industrial Avg except the Sensex is a market-cap weighted indice vs. the Dow 30 which is price-weighted. The BSE Sensex represents India's 30 largest publicly traded companies and these 30 companies account for about 20% (1/5) of the total stock market capitalization of the Bombay Stock Exchange.
