Solid investment grade corporate bonds payng 4 to 5% ?
I've been building a buy and hold bond portfolio over the last few months aiming at those yields and using various duration (3 to 10 y), closer to 4% actually, and trying to increase it, but the choice is quite limited, and with long term bonds now hardly paying more than short term bonds the longer term bonds look even less attractive. Add to this only a few bonds have a low spread, it doesn't get easier at all.
Lacking of knowledge with bonds so keen on reading advice.
Besides I find T bills convenient with IB, but just rolled some last week and they yielded around 2.38% including commission on the secondary market, little less than what Robert showed above. Order was above 1mm btw, so can't comment on the new limit, but a few months back bought several Tbills for smaller amounts without issue.
