Every month, the University of Michigan's Tozzi Financial Center compiles a list of 100 stocks that "can blow holes in your portfolio."
The list is built by analyzing value, momentum, quality, predictability, and "other" factors. The list isn't always right on, but it has a good track record. If you own one of the stocks on the list, I would advise doing some additional due diligence.
The Center's other monthly report is the Value 40
. Again, the record isn't perfect, but it's a great place to look for investment ideas.
