July 09, 2008 Cleantech Index Goes Global Cleantech rebalances its Index to include worldwide clean tech companies. SocialFunds.com -- Adding 33 new companies and dropping three, Cleantech Group has refocused the Cleantech Index (ticker: CTIUS) to reflect global growth in clean tech companies. The two ETFs, including PowerShares Cleantech Portfolio (ticker: PZD), linked to the Cleantech Index as well as structured products will reflect this change. “The Index went global because Cleantech is a global phenomenon and therefore to reflect that we must be able to include the best clean tech companies wherever they are listed,” Rafael Coven, Managing Partner & Index Manager for Cleantech, told SocialFund.com. “Previously we were limited to only the big three US exchanges.” Global companies now make up around half of the Index of 76 companies. CTIUS saw 2007 total returns of 42.9%. The 2008 second quarter returns were 8.2%. © SRI World Group, Inc. All Rights Reserved. Order reprints | Send it to a friend | Print it | Save it Top
