Thank you for your response. The account in question is an IRA that was transferred to a new account with a different brokerage in Aug, 2013. I went to the holding for both accounts on the day before and then the of the transfer. All the securities and the cash balance were transferred to the new account. The old account shows no holding on the day of the transfer while the new account has all the holdings that were on the old account the previous day.I routinely reconcile the accounts statements each month and there never a discrepancy.These accounts have 10 or more securities in them. I checked the price history of each and could find nothing.At this point, all I want to do is eliminate the account with the incorrect balance.
