Could some one please put some reasoning behind the Trading Halt. If positive results are looming and speculation has been positive for some time - even though the SP remained much the same over a period of time why would you not let the trading position run if it was to only head in a positive direction on the delivery of good news Call me a dumb arse if you like but what is a trading halt designed to do in this case albeit we are speculating as to the reason why . Obviously new at this but if anyone could give me the heads up I would appreciate it . Cheers
