There is a tip sheet that I used to subscribe to that has sent out a buy recommendation on PZC today. It is a free tip from the company in an effort, I suppose, to drum up business. The blurb on PZC read quiet well so I'm doing a bit more looking into it.

Now the question is why would they recommend the stock to ex-subscribers and potential new subscribers if there was not a very good chance of substantial gains?. Do they know something that other don't?.
