Don't Know Notice


(DK) Notice Sometimes a purchase of securities has no corresponding sale. In that case, the clearinghouse sends a DK notice to the purchaser's broker indicating that it can't match up the transactions. This can happen due to inaccurate trade symbols, price per share or quantity transacted.
