 He added that "the annual re-ranking of the Nasdaq-100 Index is an objective, transparent process that culminates in the formation of a select group of companies in a global benchmark that is the basis of dozens of licenced innovative investment products throughout the world."

 The US bourse made three additions to the index this year. In addition to Infosys Technologies, the other two companies to enter the index are Level 3 Communications Inc and Vertex Pharmaceuticals.

 Infosys became a likely entrant last month after it sold 30 million American Depository Receipts (ADRs) for $1.6 billion. The Nasdaq-100's tracking shares, known by their QQQQ symbol, traded an average 109 million shares a day this year.

 On a cumulative price-return basis, the Nasdaq-100 has risen over 1,333% since inception, and it has outperformed several major domestic and international stock indexes for the ten-year period ended November 30, 2006.

 Last year, there were 12 additions to the index. Google Inc, owner of the most-used Internet search engine, joined the index three months before it was added to the Standard & Poor's 500 Index.
