Stock of the day: Salesforce.com inc

Business software and customer contact specialist, Salesforce.com Inc. (NYSE:CRM) has just completed the acquisition of social media tracking company Radian6, which captures conversations on social media such as Facebook, Twitter and LinkedIn. Salesforce claims the acquisition allows its customers to monitor and join online conversations. The shares were up almost 80% last year and have marginally outperformed the S&P500 this year. However, skeptics remain as short interest is four times higher than the average across the S&P500 at 8.38% of total shares outstanding on loan.
