As Warren Buffett proved, buying and holding is the key to great investing. But how do you know you’re not holding onto a loser?  Aside from glancing at an earnings release, the only information many investors get about a stock comes from its price. It's tough to separate good companies from bad on such scant evidence -- but it's vitally important. Finding well-run companies at bargain-basement prices is a great way to accumulate a fortune over the long run.

With that in mind, we Fools have whipped up an easy tool to help you see how your company is doing. We can harness the aggregate intelligence of the 135,000-plus investors participating in Motley Fool CAPS to see what the community is thinking about a company today, and how they felt about it last quarter.  A change in the community's approval (signified by four- and five-star ratings) or disapproval (one- and two-star ratings) could indicate that further research is in order.

Here are the CAPS community’s aggregate feelings on salesforce.com (NYSE:CRM) and opinions on some related companies, from now and last quarter.
