The CFO doesn't have to guess, he can find out who sold from the Transfer Agent...they keep all records on shareholders and can easily find the details of who sold (or bought) a large block.... Maybe the CFO doesn't want you to know...
Transfer Agent:
"A trust company, bank or similar financial institution assigned by a corporation to maintain records of investors and account balances and transactions, to cancel and issue certificates, to process investor mailings and to deal with any associated problems (i.e. lost or stolen certificates)."
Cash is King until further notice!!!
My comments on companies are usually my opinion of long term success (years). The PPS may go up or down greatly in the meantime depending on the number of greedy suckers with money.
