frost suddenly stops buying. what does it mean? it means something big is brewing. it means he now has inside information that he can't trade on. it doesn't matter what it is, but its obviously something big.
I guess my point is that he or whomever does his buying has stopped most if not all their buying for all his interests around the same time, it could mean something or it could mean nothing at all. I'm hoping as I'm guessing you are as well that something positive is going to happen, but just because there has been a cessation in buying does not guarantee it.
