"All of Pearson's major businesses sustained their strong trading momentum throughout 2010," the company said in a statement today. "We will report healthy sales growth and further margin improvement, fueled by our consistent investment in the global learning industry, in digital services and in developing economies." Pearson said its Financial Times division will report strong profit growth as the advertising market continued to improve. It also said that its Penguin publishing group has benefited from the expanding digital reading market. "We performed strongly in our key trading season and will report record results despite tough conditions in the physical book retail market," Pearson said. Pearson shares spiked to a 52-week high of $17.14 this morning and is now trading up almost 6% to around $17.05.
