Bonza OR Buster?

ASH have dribbled down to 49 cents on small volumes daily - @ 49 cents pays 3 cents Fully Franked half yearly OR has for past two years.

@ 49 cents, 6 cent s yearly is 12.24%
add Franking = 15.6%

So are their material changes going on @ ASH, if so the market should be advised!?, if business is going as per usual & last years growth strategy is being absorbed smoothly - where might ASH be at the end of this Fin. Year?

Notice a couple of keen buyers at 45 cents - will patience reward them OR is there something afoot that we should all be informed about?
