SEDI Insider filings are due 5 calendar days after sale......and so far I see none for Chen, Fairfax/ Watsa or other BoD members. This may indicate either
1. strong belief they will eventually be able to sell at even higher prices than last week, and/ or
2. they may have undisclosed material information and were thus prevented from trading. This could be, since a court hearing is set for next week re FB claim
And once again, if you can, promote the idea of Jeff Bezos joing BB Board of Directors.
