Of late i have noticed there is quite a bit of market manipulation on smaller cap essentially mining stocks being the most common prior to them running.Seller places large orders to flush out others before removing, would seem like some type of accumulation.I have noted this has occured in PSY,GER,ASZ,DDT,GXY,SUD to mention just a few prior to their strong run up

I have a couple of questions for the more knowledgable

a,Is this classic accumulation Style ?

b,Is this activity rife in this smaller cap area?

c,What are the more common types of manipulation and how can one spot it?

d, what is the main purpose, tree shaking, accumulation or other?
