market returns and hotcopper

One of the best ways to pick up on hotcopper posters or posters outside of hotcopper is to find those that are making good returns and follow them.If you pick up on those posters and work out their methods and then implement those methods for yourself.It has not been hard for me to pick up those people who are making more than 50%return pa or probably closer to 100% or more.Has anyone been able to recognise these people amongst the ramping and down ramping?
