Here in Silicon Valley, this year has not been kind for stocks. The stocks of some of our biggest companies, including Google, Apple are down significantly. Which is too bad. I own some of that stock. So too are environmental stocks, apparently.
Cleantech Indicies has a stock index called “The Cleantech Index” (AMEX:CTIUS), which they describe as:
The first, and only, stock market index intended to reflect the surging global demand for clean technology (cleantech) products and services. By tracking the market performance of the leading publicly traded* cleantech companies, CTIUS is the industry standard index that underlies a growing range of financial products (such as exchange traded funds). As such, investors now have an easy, cost-effective, and liquid means to invest in the broadcleantech investment category – and do so with far less risk than previously possible.
Currently, CTIUS is comprised of 47 companies that are leaders in cleantech innovation and commercial deployment across a broad range of industry sectors: from alternative energy and energy efficiency to advanced materials, from air & water purification, eco-friendly agriculture/nutrition to power transmission, etc.
As you can see by this chart here, the Cleantech Index is down by something like 40% from its highs in December
Now may be an interesting time to invest if you’ve been looking for a way to invest in clean environmental technologies. But before you buy, take a look at some of the stocks in the CTIUS Index:
