subject: 3 Keys to Selecting the Best Penny Stock Picker [print this page] 3 - Make sure it's cheap stock specific3 - Make sure it's cheap stock specific. What I mean here is that cheap stocks and greater valued stocks behave differently. It just makes sense because it takes a great deal less outside trading influence to directly affect the price of a cheap stock versus a greater priced one. Some programs I've found attempt to go after stocks all across the board and suffer between cheaper and greater priced stocks as a result, so make sure it's cheap stock specific as these make for the best penny stock pickers through and through.
