Warren Buffett has proven the key to investing is "buy to hold." The problem is, how do you know you're not holding onto a loser? For many investors, the only information they get besides glancing at an earnings release is the stock price. Separating the good from the bad is difficult, but 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 at The Motley Fool have an easy-to-use tool for you to see how your company is doing. We use the intelligence of the 135,000-plus investors participating in Motley Fool CAPS to see what the community is thinking about a company today, and compare that to how they felt about it last quarter. A change in approval (signified by four- and five-star ratings, the two highest) or disapproval (one- and two-star ratings) could indicate that further research is in order.
