Greater Dallas Chamber Index

The Greater Dallas Chamber, presides over the Closeing bell.

The Greater Dallas Chamber, in collaboration with The Nasdaq Stock Market, Inc. (Nasdaq:NDAQ), launched a new one-of-a-kind regional technology and life sciences index on January 12, 2006, the NASDAQ/Greater Dallas Chamber Index ("the Index"). This index tracks the performance of publicly held technology and life sciences companies in Dallas/Fort Worth (DFW).
The DFW region commands one-third of all tech activity in Texas. A total of 41 companies totaling approximately $325 billion in market capitalization will be included in the Index. The purpose of the index is to highlight the strength of the technology and life sciences sector in the DFW region and to provide increased visibility for DFW based businesses.
This Index measures the health and growth of the DFW region's localized technology economy by tracking the leading public technology and life sciences companies driving this growth, as determined by the Greater Dallas Chamber's definition and eligibility. This impressive array of U.S. and foreign companies represents all four core technology areas: high tech manufacturing, information activities, professional and technical services, and bio/life sciences.
NASDAQ assigned the ticker symbol (DTEC) to identify The Index. The ticker went live today on the NASDAQ website (www.nasdaq.com) and on the TBC website (www.dallastbc.org) and will remain. It will be updated every 15 seconds.
Companies eligible for this initial index include: Public companies listed on the NASDAQ Stock Market, New York Stock Exchange or American Stock Exchange with U.S. headquarters located within the 12 county DFW metropolitan area that are classified in the technology industries as defined by either the American Electronics Association or BIO (using NAICS or SIC codes) and have intellectual property (IP) as a core asset as declared in their 2005 SEC 10k statements.
