Predatory Shorting, page-34

Not mums or dads i think. Probably not even daytraders. Management would have to declare their purchases.

Maybe brokers churning shares to suppress the price in the hope that they can pick up shares from some frustrated punters selling out.

Most sell orders are small value, well under a thousand shares, and appear very rapidly. I use Commsec and if you click refresh data every few seconds you'd be surprised at how quickly the sell orders appear, and small value buy orders for that matter. Algorithmic trading: computers running the show.

Then again, I might be wrong.
