Insider trading was, is and always will be there as long as market function. You need is to be able to identify and join it. It is extremely hard and individual stocks can be manipulated very easily. This is one of the reason why I trade index futures, it is a lot harder to manipulate a basket, the execution is superior to anything and the leverage is what ever you like it to be (even 100%), you do need to know on how to use it though.
