BSE TECk Index Click for Free-float Concept Download Index Constituents Index Calculation & Maintenance Click to search Historical Notices on Index Replacements Introduction 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.

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.   History of Replacements in BSE-TECk Index   Date Outgoing Scrips Incoming Scrips 07.01.2002 Visualsoft Tech.
