When a stock hits a fresh low, it can either signal a dirt cheap dream stock or a dreadful stock to avoid. Separating the wheat from the chaff 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'll use the aggregate intelligence of the 110,000-plus investors participating in Motley Fool CAPS to see what the community is saying about stocks hitting 52-week lows today. The community's approval (signified by four- and five-star ratings) could be a sign that further research is in order.
