All the DTC sheets are good for is to show the movement of shares from one clearing firm to another. Companies can use this information to track whether or not a large shareholder has been selling when he has been claiming he was not, but other than that, the info is useless.
We are apt to shut our eyes against a painful truth... For my part, I am willing to know the whole truth; to know the worst; and to provide for it. --Patrick Henry, Patriot and Hero of the American Revolution
