Clean Energy Exuberance?

Oil prices fall to a "mere" $73 a barrel, and clean energy stocks fall too. The WilderHill Clean Energy Index (ECO), which tracks clean energy stocks in the United States, has dropped about 10 percent from the beginning of the month. But while the market is volatile, investor interest in the exchange-traded fund that mirrors the index is surprisingly steady, says Rob Wilder, president of WilderShares, which manages the index. “We’re still getting $2, $3, $4 million of net inflows,” he said. “There have only been two days in the last year that we got more sells than buys.”
