There are great sites like shortman you can access to work out if anyone is shorting whatever your into and the level of it which can be a good indicator of several things.
KZA has almost zero shorts declared - interesting there was some around Mar to May in short spikes then almost complete flat line since - if there was informed players then wouldn't they be shorting if there WAS bad news afoot?...
