The NASDAQ-100 Index to Undergo a Special Rebalance


NEW YORK, April 5, 2011 (GLOBE NEWSWIRE) -- The NASDAQ OMX Group, Inc. (Nasdaq:NDAQ) announced today the NASDAQ-100 Index® (Nasdaq:NDX), will undergo a Special Rebalance effective prior to market open on Monday, May 2, 2011. The Special Rebalance will not change the methodology used to calculate the NASDAQ-100 Index nor the Index Securities.

After substantial research and consideration, NASDAQ OMX decided to enact a Special Rebalance in order to bring the weights of the Index Securities closer in line with their actual market capitalizations.

"The Special Rebalance reflects our commitment to ensure the NASDAQ-100 Index remains a relevant benchmark for investors around the world who track the performance of the U.S. equity market," according to John Jacobs, Executive Vice President, NASDAQ OMX Global Index Group. "The NASDAQ-100 Index will remain an objective, transparent, rules-based index and will be comprised of the same large-cap growth companies that have a legacy of leadership and innovation."

As a result of the Special Rebalance, the underlying characteristics of the NASDAQ-100 Index will remain intact and the sector weights will remain in the same relative order and magnitude. For more information about the Special Rebalance, including the results, visit

The Special Rebalance of the NASDAQ-100 Index will be enacted based on Index Securities and shares outstanding as of March 31, 2011.*

The NASDAQ-100 Index is composed of the 100 largest non-financial stocks listed on The NASDAQ Stock Market® and dates to January 1985 when it was launched along with the NASDAQ Financial-100 Index®, which is comprised of the 100 largest financial stocks on NASDAQ®. These indexes act as benchmarks for financial products such as options, futures, and funds. The NASDAQ-100 Index is re-ranked each year in December, timed to coincide with the quadruple witch expiration Friday of the quarter.

On a cumulative price return basis, the NASDAQ-100 Index has returned approximately 1771% since inception, although past performance is not indicative of future performance. The NASDAQ-100 Index is the basis of the PowerShares QQQ Trust (Nasdaq:QQQ) which aims to provide investment results that, before expenses, correspond with the NASDAQ-100 Index performance. In addition, options, futures and structured products based on the NASDAQ-100 Index and the PowerShares QQQ Trust trade on various exchanges.
