arms 12million shares buyback lasting nearly 1 year
who are they planning to buy them off.surely they don't believe they are going to buy that many at these levels but wouldn't they want to buy them cheaper
l am a little confused...wouldnt it be better spent paying debt off?
if this had a bit more exposure and no funny buggers where it drops on low volume to then get a few big boys step up it would clearly be more than current levels
l am not complaining as it helps me buy dribs and drabs but just makes little sense to me
