Absolutely right, Duke. If this stock is being manipulated (a big "if"), it is certainly not being done by a major player. Way too much to lose if they get caught, just not worth the headache. They would simply launch a hostile take-over bid.
I rarely buy anything that looks like a conspiracy theory unless someone gives me something that looks like evidence. Every phenomenon can easily be explained by a number of completely specualtive conspiracy theories. Coming up with evidence supporting the theory, that is the hard part.
