tahi,
There isn't that much shorting that is outstanding. As a matter of facts, as of the 14th current we only had approx. 1,220,000 shares shorted and uncovered, which is only close to 1/2% of our total shares on issue.
IMO, like someone else in these threads said, some investors have had enough of MPO, they are sick and tired of seeing their money whiltering away, and they dump as a result.
