The Bombay Stock Exchange has reshuffled its 30-share sensitive index, and added the scrips of Tata Consultancy Services and National Thermal Power Corporation to the index.
The BSE said in a release that it had removed the scrip of Hindustan Petroleum Corporation Limited and Zee Telefilms from the Sensex.
The changes would take effect from June 6, 2005, the BSE said.
The last time the constitution of the benchmark index was altered was on November 27, 2004, when Mahanagar Telephone Nigam Ltd was replaced by engineering and construction major Larsen & Toubro Ltd.
L&T was replaced by Maruti Udyog just four months prior to this, on May 19.
The biggest recent reshuffle of the index took place on November 10, 2003, when Castrol, Colgate-Palmolive, GlaxoSmithKline Pharma, HCL Technologies and Nestle were replaced by Bharti Tele-Ventures, HDFC Bank, ONGC, Tata Power and Wipro, respectively.
The index has been recast a dozen times in its 19 and a half year history to reflect the ever-changing importance of industries in the local and global economy.
It was launched on January 1, 1986, and was calculated on a full market capitalisation basis. But the calculation was shifted to the free-float methodology with effect from September 1, 2003, following the global trend.
