Market manipulation via various forms including coordinated shorting/ poor journalism represents the greatest financial concern to me as it impacts on the value of my whole portfolio and the wider market. BIG is one stock and represents a small part for most. Management need to do some things but there needs to be a directed move to eliminate manipulation. I don't care who is manipulating and how. it just happens that eyes are on AFR because that is where the smoke is coming from.
