How should I be investing in bonds as part of a diversified portfolio?
For most people, you don't want individual bonds. Unless you are investing very significant amounts of money, you are best off with bond funds (or ETFs). Here in Canada, I chose TDB909, a mutual fund which seeks to roughly track the DEX Universe Bond index. See the Canadian Couch Potato's recommended funds. Now, you live in the U.S. so would most likely want to look at a similar bond fund tracking U.S. bonds. You won't care much about Canadian bonds. In fact, you probably don't want to consider foreign bonds at all, due to currency risk. Most recommendations say you want to stick to your home country for your bond investments. Some people suggest investing in junk bonds, as these are likely to pay a higher rate of return, though with an increased risk of default. You could also do fancy stuff with bond maturities, too. But in general, if you are just looking at an 80/20 split, if you are just looking for fairly simple investments, you really shouldn't. Go for a bond fund that just mirrors a big, low-risk bond index in your home country. I mean, that's the implication when someone recommends a 60/40 split or an 80/20 split. Should you go with a bond mutual fund or with a bond ETF? That's a separate question, and the answer will likely be the same as for stock mutual funds vs stock ETFs, so I'll mostly ignore the question and just say stick with mutual funds unless you are investing at least $50,000 in bonds.
