Solar Stock Losers: Power-One

NEW YORK (TheStreet) - It's been quite a ride up for solar inverter company Power-One PWER in 2010, with a year-to-date return of 140%. Some recent negative pressure on Power-One shares, including selling on Wednesday, suggests that the solar inverter company is firmly on the radar screen of investors, from the longs to the shorts, who like to dabble in volatile solar stocks. Liquidity in Power-One shares, a company which came from nowhere two years ago to be among the largest solar inverter companies in the world today, is also showing signs of maturity, with average daily volume now over 5 million shares. That may not be Citigroup territory, but for a solar inverter stock, it's significant trading level. Advanced Energy Industries AEIS another solar inverter company coming off strong earnings, only has average volume of 500,000 shares. On Wednesday, Power-One shares are down 5% in the morning, and 3 million shares, more than half the solar inverter company's daily volume of trading, were in play by 11 a.m. To read the rest, head over to TheStreet.comMarket News and Data brought to you by Benzinga APIs
