I have Ford and GMAC short maturity individual bonds. GM has been in the news lately with talk of bankruptcy... I think that it is overblown, but even talk of it should not be viewed as a good thing. GMAC is independent of GM, but it has also been in the news with some subprime housing paper. Ford stock has been doing well lately... a good sign. Given equal yield, I would favor Ford right now. A year ago, I would probably have favored GMAC.
Again... either of these companies should be bought in moderation. I don't have more than 2% of my portfolio in either one... more than 5% would be pretty risky imho.
