For a long time, bond investing was considered a sleepy backwater. You bought a bond and just clipped coupons as you waited for it mature. Boring! Then Bill Gross discovered that bonds could be traded. He founded Pimco and proceeded to make lots of money from bond investing in sometimes questionable ways. Bloomberg Opinion columnist Matt Levine co-hosts in this special Odd Lots episode with Mary Childs, who's just published a book on Gross called "The Bond King: How One Man Made a Market, Built an Empire and Lost It All." We discuss some of Pimco's most famous trades, whether Gross was a good investor, and his legacy to the world of bonds.
