Buy Low/Sell High Candidates

I could list everyone who is not off to a good start, but you can check stats for that. I checked through Yahoo and these are guys you may be able to get cheaper because of their cold start/yahoo ranks. These are also guys who you may be able to cash in on because of their hot start/yahoo ranks.
