First up is customer relationship software giant Salesforce.com ( CRM). Salesforce is the incumbent in the enterprise CRM software, helping around 100,000 businesses interact with their own customer lists. The firm's critical role comes with some big benefits -- chief among them is the fact that its customers are extremely sticky and unlikely to move their massive data rolls onto competing offerings. Still, shorts are betting against Salesforce.com en masse right now. The firm sports a short interest ratio of 11.1. >>2 Could Stocks to Buy for 2013 In a world where ROI is being scrutinized much more intently for business spending, Salesforce's clear-cut revenue generation is a big plus. Companies can make a pretty easy case for the extra revenue that the platform's sales tools bring in -- as well as the IT costs they save by using Salesforce on the cloud rather. Software-as-a-service is also a more lucrative model for software firms like CRM. Instead of selling a software license and then trying to convince customers to spend big bucks on the next iteration of the software, the cloud model lets CRM charge recurring fees while trickling feature improvements onto the platform. Right now, investors are anxious that Salesfoce is trying to squeeze more cash out of a saturated market. But new add-on services and huge growth opportunities abroad should help to calm some of those concerns. A fat net cash position on CRM's balance sheet ensures that this company can withstand some economic hiccups in 2013. Earnings at the end of February could be a big catalyst for this stock.
