If this isn't a massive signal to the market then I don't know what is.
Bruce Flatt, arguably one of the best capital allocators, is allocating his personal capital from $BAM to
$BN. He sold millions of $BAM and purchased
$BN with the proceeds.
A large disconnect in the price of
$BN for the assets/investments owned.
Remember - insiders buy for ONE reason and sell for many different reasons.
