Cleantech, with its intoxicating mix of high-tech promise and save-the-world bloody-mindedness, has fallen harder and faster in the destruction that has visited growth stocks in 2008.
Underscoring the sector’s risks, German solar cell maker Q-Cells cut its 2009 outlook on Tuesday, saying slack demand could linger until the middle of next year amid a growing industry price war. The stock lost nearly a fifth of its value in trading and the news sent down shares of rival companies.
But while it’s too early to say when the selling might be over for solar and wind stocks, gems lie in the rubble of collapsed valuations, ready for investors to snap them up when markets recover their appetite for growth and its attendant volatility.
To understand what is possible, take measure of the decline: The WilderHill Clean Energy Index, composed of around 50 renewable energy and conservation stocks, has lost three quarters of its value year-to-date, twice the loss of the S&P 500.
