S&P BSE TECk

The decade of 1990s saw the emergence of the TMT sector as a major force in the Indian economy. The remarkable growth of this sector was reflected in the financial markets.

Going by the trading pattern, around 19% of the turnover on the stock exchanges is taking place in TMT sector stocks. These stocks collectively account for 15% of the total market capitalization. The investment interest in technology stocks continues unabated.

Recognizing the growing importance of the TMT sector, BSE TECk index was launched in 2001.

The general guidelines for selection of constituents in BSE TECk are as follows:

Eligible universe
Scrips classified under information technology, media and telecom sectors that are present constituents of BSE-500 index form the eligible universe.

Trading Frequency
Scrips should have a minimum trading frequency of 90% in preceding three months.

Market capitalization
Scrips with a minimum of 90% market capitalization coverage in each sector based on free-float final rank form the index.

Buffers
A buffer of 2% both for inclusion and exclusion in the index is considered so that movements in and out of the index are minimized. For example, a company can be included in the index only if it falls within 88% coverage and an existing index constituent cannot be excluded unless it falls above 92% coverage. However, the above buffer criterion is applied only after the minimum 90% market coverage is satisfied.
