PENGROWTH ENERGY CORP. $6.37 (www.pengrowth.com) has gained nearly 30% in the past three months. That’s mainly because the company has successfully completed its plan to sell some of its less important oil and gas properties in Western Canada. The cash from these sales will help Pengrowth speed up the development of its Lindbergh oil sands project in Alberta. As well, the company’s monthly dividend of $0.04 a share still seems safe and has a 7.5% annualized yield. Buy.
