2. Power-One ( PWER) Company Profile: Power-One is the world's second-biggest provider of solar inverters. The company is also among the largest providers of power conversion and power management solutions in the world. Share Price: $4.24 (Dec. 2) 2011 Stock Performance: -58.3% Analyst Consensus: Power-One investors are licking their wounds this year as the stock has fallen from $12 in February to about $4. Power-One has suffered from continually guiding forecasts below analysts' estimates. The company most recently saw a drop in third-quarter profit and offered a weak outlook for the fourth quarter because of the global macroeconomic uncertainty that has dented renewable energy firms around the globe. However, the company still pulls in 11 "buy" ratings from the 20 analysts following the company. The average price target of $6.29 implies upside potential of 48% over the next 12 months, although that would still fail to regain the 2011 high of $12.14. Bullish Case: Cantor Fitzgerald analyst Dale Pfau in late October reiterated a "buy" rating on the stock, noting that Power-One continues to gain market share in a challenging industry. "Based upon the challenging solar environment, investors should be heartened by solid profitability, continuing market share gains, and an outlook for improving margins," Pfau wrote in an Oct. 28 research note. "We believe that the shares are attractively valued at current levels, and we suggest that investors accumulate shares in anticipation of further market share gains."
