Maybe granny isn't telling you the entire story. It seems the person managing her finances is managing her own future inheritance. You should ask HER what is going on. Maybe granny got into trouble with the IRS and needs the loss to carry-back and offset some stiff penalties??? Or, perhaps Granny gets the final say in all transactions in which case the manager should bear NO responsibility because of the obligation to follow the directions of the owner. People, including elderly people, can be quite difficult and even contrary. There are so many possibilities that you should consult the person managing the money. IMHO
