I put my folks into 10-year T notes and the long bond a few years ago with an average yield of 7%. As rates have plummeted the T notes and long bond have skyrocketed, producing nice profits. Does antone know of a way to "protect" those profits? Are there "put options" on the T notes and the long bond? Or any other way to hang onto the profits, before they eventually melt? Any response will be greatly appreciated.
