Got to ask the question
As we entered the asx 200 the 150 Mil in shorts came from the big end of town having to buy, so let's say as discussed before that they cover there asses if a share price drops as well as rises, so do the shorts come into play if the company who bought the shares are shorting they own shares and not lending them.out, a genuine question, do they need to cover in this instance,again genuine question??????
