Ann Arbor, Michigan [RenewableEnergyAccess.com] The Cleantech Capital Group this week entered into an agreement with the American Stock Exchange to begin publishing the Cleantech Index: a new index comprised of publicly traded companies engaged in the cleantech industry.The Cleantech Index is comprised of 75 companies with a combined market capitalization in excess of $100 billion. Companies in the Cleantech Index have at least 50 percent of their sales obtained from cleantech products and services. According to the group, calculations from back-testing of the Cleantech Index suggest the past five and three years significantly outperformed the S&P 500 and NASDAQ indices. “Cleantech” is defined as any knowledge-based product or service that improves operational performance, productivity or efficiency while reducing costs, inputs, energy consumption, waste or pollution. The cleantech concept is not specific to a particular sector: it encompasses energy generation, energy storage, energy infrastructure, energy efficiency, transportation & logistics, water purification & management, air quality, materials & nanotechnology, manufacturing/ industrial, agriculture & nutrition, enabling technologies, materials recovery & recycling and environmental IT. Cleantech markets represent annual global revenues greater than $150 billion, and segments such as wind and solar power boast 5-10 year compound annual revenue growth rates as high as 35%. “The Cleantech Index will provide investors with a vehicle to diversify into the emerging “cleantech” investment category while helping bring greater liquidity to publicly traded cleantech companies and, by doing so, encouraging capital formation for privately held cleantech enterprises with strong IPO potential” says Nicholas Parker, Chairman of the Cleantech Capital Group. Parker adds: “The Cleantech Index is the premier investment vehicle developed for capturing the opportunities associated with the substantial increase in the economic value of clean technologies. We believe this value will inevitably be unlocked as global markets adjust to the linkages between human health, economic development and resource sustainability.” Discussions are underway relative to the licensing of the Cleantech Index for financial products, including an exchange-traded fund that will track the index. The index will be rebalanced each March, June, September and December. An advisory board comprised of leading academics and thought leaders will be announced shortly.
