John Heinzl was kind enough to quote me in his Investors’ Clinic column titled Why only millionaires should invest in bonds directly:
Now, it’s true that bond ETFs typically roll over holdings one year before they mature, because at this point these securities are considered money-market instruments. But in an environment of rising interest rates, a bond ETF that follows a sell-before-maturity policy would buy new, higher-coupon bonds sooner than an identical portfolio of bonds that held to maturity, and the higher income would make up for any capital loss incurred as a result of selling early, said James Hymas, a fixed-income expert and president of Hymas Investment Management.
Bond ETFs have several advantages, he points out. Because ETFs buy in volume, they get much better pricing than retail investors could obtain through their broker, and this pricing advantage for most ETFs will outweigh the management expense ratio. Bond ETFs also provide instant diversification. The notion that bond ETFs don’t mature and should therefore be avoided makes no sense, he said.
“Anybody investing less than $1-million in bonds should do it through ETFs,” Mr. Hymas said. “If you have more than $1-million, then you can talk about buying individual issues, but if you have less than $1-million you’re either going to have poor diversification or poor pricing, perhaps both.”
The Globe’s website shows one comment worth addressing:
I disagree entirely. A bond costs $5K to buy and nothing to hold. For 70K you can set up a 7 year ladder with one bond maturing every 6 months. You hold every bond until it matures, reinvesting each matured bond with all the accumulated interest in the account in a new 7 year bond. When you retire you can use the interest payments as income if you like. You will earn the same as a second OAP, without the clawback.
If you don’t have 70K yet, you buy one $5K 7 year bond every 6 months for the next 7 years to set up.
It is not rocket science, I have been doing it for 15 years. The pros like Hymas hate it because, apart from the small fee when you buy a bond, you pay no fees at all.
A Bond ETF will have a management expense ratio of 25-35bp. The bid-offer spread on seven year bonds purchased in amount of $5,000 will almost certainly exceed this. Additionally, there will be costs associated with further trading, unless you spend amounts exactly equal to your coupon income.
Another commenter suggested:
It is certainly possible to create your own bond ladder as you describe, and there are benefits to that. But the costs are also hidden by the lack of transparency and liquidity in the smaller denominations. Perhaps $1M is overkill, but probably $25,000 is a practical trade-off between price/cost and yield.
I just checked a broker screen and spreads on medium-term corporates are about 35bp for quantities of $1,000. Sorry – I don’t know precisely where the price breaks are, or how much better pricing is at the 25,000 level.
I suggested $1-million because then you can buy 20 bonds in lots of $50,000. The ETF also has the advantage of greater liquidity, as well as freeing you from the tender mercies of your custodial broker’s bond desk should you need to sell, which are often not very tender.
Additionally, note that most retail bond desks will make only a very limited number of names available to investors – proper diversification of a bond portfolio will always be very difficult for retail, even those who do have $1-million.
For more on this theme – which addresses in more detail the ladder / ETF decision – see my March 2010 publication from the Advisors’ Edge Report.
Update, 2011-7-8: One commenter made an excellent point:
And have you ever tried to sell a bond? Sure, if you’ve laddered everything nicely you shouldn’t need to. But sometimes $hit happens and you need money unexpectedly. I’ve tried twice, once through W’house, once through e-trade. It took them days to get back to me with a (horrible) price, by which time I’d raised cash elsewhere. If you’re buying bonds directly, be really, really sure you’ll hold them to maturity.
One common theme in the comment is the view that holding bonds directly is better because “Transaction fees and the spread are a one time cost whereas the MER is forever.” In fact, transaction fees and the spread are a recurring cost, paid anew every time you roll a rung of the ladder. And, as stated in my post above, the spread for medium term corporates in small quantities at one broker is about 35bp per annum – when you express the spread as a difference in yield.
