I guess RM was just following the cue of Parnel who cashed in a chunk of his ACE holdings, though I believe the latter did that when ACE was hovvering in the $42 range, while RM would have done it in the current $38 range. Though being able to buy the shares at the price he did, RM came out well ahead of Parnel. I've held onto mine, and am awaiting the special payment that was approved at the AGM. Then I might sell some ACE to buy some JAZZ.
But it does look like RM is preparing for his departure. Once JAZZ and Maintenance are spun off, the fun will be gone and ACE will just be clipping coupons and monitoring monthly payouts like a retired senior...
