Ann: MYX provides investor update & announces on market buyback, page-31

Yes, buybacks are normally carried out by a third party. And yes the market often seems unappreciative of this management ploy to supposedly manage capital.
Personally, we'd have preferred a capital return from MYX rather than the buyback letting us invest elsewhere.
On the positive side, if EPS increases due to less shares on the register and divs follow suit, then holders benefit. Theoretically. And, depending on senior exec incentive programmes, so does management.
Do you trust MYX to look after its shareholders? History would suggest otherwise. Cheers.
