Yes, and some ( of us ) just know bits of the puzzle but not enough to see the whole picture. Though as you point out someone knows more than any one(s) else, to the extent that they have access to all knowable information. And then as Ron points out ( often ) there is that which can not be known, such as how a judge will rule.

My experience leads me to watch the tape and the price of the stock and the volume to "see and hear" what the more informed know and are acting upon. Today, it does seem someone(s) knows something. There, I said it.
