Many of those who bought BAM shares got 2 year restricted certs that are probably becoming saleable for the first time right around now, One or more large owners of those may be getting out after a long wait.
Additionally, the Bourque 4-company merger also was voted on and made official 2 years ago this week. Depending on how many of the owners of the companies that were bought at that time (e.g. Kim S and whoever were minor co-owners with him at that time) got restricted certs as part or all of their proceeds in that deal (as opposed to unrestricted shares), these people could also finally be selling after a long wait.
It depends on the exact date of those certs, which we don't know, we can only approximate. But I recall Sept 24, 2011 was a key transaction or board voting date, so it figures big trading volume started Tuesday Sept 24, 2013 and continued today.
