There's been any amount of shares for sale the last six months. Any fundie who wanted a decent bite would have had no trouble. Of course getting a decent lot really cheap in the 60s may have been a bit harder. It's the fact that no new fundie tried to get a decent slice that has caused this coming buyback. And I'm sure DDH will have little trouble buying back a decent amount at below what I consider fair value.
Without today's buying there have been in excess of 10m bought in the the last five trading days mostly between 68-72c. Even allowing for the 2m crossed yesterday, the has been quite a bit of liquidity recently. And that hasn't included any buybacks

I think some fundy/ies have been buying.

Wouldn't be surprised if the buyback may have started today with a small amount early. We'll see tomorrow.
