Shorting Should be banned on all exchanges in all countires!
Regulators and governments who have approved strategies like shorting; they either did not understand what they were sighing or they were going to benefit from it themselves.
Shorting is the #1 reason why stocks fall so fast; most investors tend to hold on to their stocks when there is bad news hoping that it will pass; so they don't sell and therefore the stock should not plummet as much right? but when you have white collar heartless criminals dumping your own shares behind your back; that is when the stock plummets big time.
This all started a long time ago in New York when there was a stalemate between buyers and sellers; so brockerage firms came up with this dirty trick where they could buy and sell, short and cover and churn and burn their ignorant and innocent customers; they benefitted both from commissions and capital gains.
