The recent course of sales/volume data on EXS certainly doesn't suggest much 'trading' activity in EXS of late imo:-- http://www.tradingroom.com.au/apps/qt/quote.ac?section=pricehist&sy=tpl&code=EXS#tabs
... and not many "day traders" would have entered into this stock today based on that (19cps) offer and considering where the sp closed yesterday (@ 18cps)!
