Bonds always figure in there somewhere even when he does sensitivity analysis with the variables. The stumbling block is always in the assumptions, not the math formulae.Michael Jameshttps://www.blogger.com/profile/10362529610470788243noreply@blogger.comtag:blogger.com,1999:blog-5465015914589377788.post-48179635338627939022008-02-03T22:21:00.000-05:002008-02-03T22:21:00.000-05:00Hi Brian,It's certainly true that holding bonds in...Hi Brian,<BR/><BR/>It's certainly true that holding bonds in years where stocks are down helps to cushion the blow. However, these savings are relatively small compared to the losses that come from failing to be fully invested in stocks in years where stocks perform well.<BR/><BR/>For money I won't need for at least 3 years, I'm content to invest it 100% in stocks, ignore the media, wait out poor periods for stocks, and make more money in the long run.Michael Jameshttps://www.blogger.com/profile/10362529610470788243noreply@blogger.comtag:blogger.com,1999:blog-5465015914589377788.post-30510586806430871032008-02-03T19:21:00.000-05:002008-02-03T19:21:00.000-05:00Hi Michael,Lets look at the past... 2002 & 2003 th...Hi Michael,<BR/><BR/>Lets look at the past... 2002 & 2003 the TSX was down about 13% each year. Most people (media) thought this was the end of the world. If you look at some balanced funds the return in these years was less than half the down side.<BR/><BR/>Now looking in the future, what if the bonds did not distribute income only capital gains? Would you buy? Bonds give you a different asset class, very important in down years!<BR/><BR/>regards,<BR/><BR/>BrianAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5465015914589377788.post-60862240101298999492008-02-03T09:19:00.000-05:002008-02-03T09:19:00.000-05:00CanadianFinancialDIY:I agree that the stumbling bl...CanadianFinancialDIY:<BR/><BR/>I agree that the stumbling block is assumptions and not the math. I hoped to demonstrate that by showing what a radical difference it makes to change the interest rate on borrowed money. Increasing the borrowing rate by about 4% caused the optimal strategy to go from nearly 3:1 leverage with a big block of bonds to no leverage and no bonds.<BR/><BR/>For this particular analysis, I used John Norstad's data from the US from 1926 to 1994. In the past, I have used figures from other researchers over other (long) time periods, and things change, but the conclusion to avoid bonds has been a constant. However, I don't claim to have done an exhaustive survey of all data collected by all researchers.<BR/><BR/>One could repeat this analysis using, say, 80 rolling 10-year periods. Suppose that in 10 of those 80 periods, the result is that involving bonds in your asset allocation helps returns. The question then is how much did it help in those 10 periods, and how much did you give up in the other 70 periods.<BR/><BR/>I'll think about all this some more and see if I come up with anything worth posting.Michael Jameshttps://www.blogger.com/profile/10362529610470788243noreply@blogger.comtag:blogger.com,1999:blog-5465015914589377788.post-5263641977227983722008-02-02T15:10:00.000-05:002008-02-02T15:10:00.000-05:00CanadianRetiredGuy:I have always maintained that m...CanadianRetiredGuy:<BR/><BR/>I have always maintained that money you need over the next 3 to 5 years should not be in stocks. If your $250k in fixed income is there to dip into in case of a prolonged drought in stocks, then your choice seems quite rational to me.<BR/><BR/>But, if you have more money in fixed income than you will need over the next 5 years, then I can't find a rational reason for this. Stocks go down and stocks go up. No money is made or lost unless you buy or sell.<BR/><BR/>I have several Aunts and Uncles who won't touch stocks at all because they wouldn't be able to sleep at night if they did. In a sense they are being rational about understanding their psychology. But this is sort of like being rational about one's own irrationality.<BR/><BR/>The only family member in my parents' generation I have talked to about the advantage of stocks is my mother who is doing quite nicely with her dividend income. However, she is probably more rational than I am.Michael Jameshttps://www.blogger.com/profile/10362529610470788243noreply@blogger.comtag:blogger.com,1999:blog-5465015914589377788.post-34906481102606778622008-02-02T14:35:00.000-05:002008-02-02T14:35:00.000-05:00I've got a rational reason to invest in bonds for ...I've got a rational reason to invest in bonds for the long term -- it allows me to sleep at night.<BR/><BR/>I am 61 and have stopped working and have no pension income. I have a $750k (or so) portfolio with about 34% in bonds. When the market drops like it did in January I sleep well knowing I have $250k that is in fixed income and that it is relatively safe.Anonymousnoreply@blogger.com
