Forward to the Farm In, page-22

The easiest way to avoid that is to hold off buying in until the farm in is announced. Keep you powder dry and you wont lose anything except the initial rise.
Besides broker manipulation is achieved with a tiny percentage of the registry so even the tightest hold will never stop these swings. I am sure most share investors would play this game if they had the means and ability. It's easy money on most plays (but not always) and it's impossible to regulate in a liquid market.
Perhaps you would feel more comfortable investing in private limited companies where shareholders are restricted in their ability to sell and there are no reporting requirements.
