Oh, I agree that the purpose of bonds is to blunt loses. I just don't see the point of blunting loses and reducing gains when I still have 35 years left until retirement. I mean, what do I care if my portfolio absolutely tanks 10 years from now due to a huge market crash? I still have 25 years left to retirement. Thats plenty of time for the market to bounce back. Therefore, I think it makes sense to invest for the most growth possible.
I think time is all the hedge you need until time stops being such an excellent hedge. That is when I plan to start heavily investing in bonds.
Well... does your ability to take on risk suddenly fall off a cliff at 10 years before retirement? Or does it slowly increase over time as your time horizon decreases, as you approach the time that you'll actually need the money?
Or, here's another way of looking at it. The reason you want to switch to a bond mix (let's call it 60/40) ten years before retirement is to blunt the risk of a massive loss right before retirement, when you'll need the money. But what if that massive loss happens right before your planned switch to the 60/40 bond mix? Your ability to make up the loss will be severely curtailed by the switch in asset allocation, with all those bonds in your portfolio. Of course, this isn't
as disastrous as a massive loss just before retirement. But it's still really bad. So maybe you should hedge that by switching to, say, a 70/30 bond mix a few years before your planned 60/40 switch. But wait! What if a market crash happens right before your planned 70/30 switch? Well, again, not nearly as bad as the crash before retirement or the crash before the 60/40 switch, but still kind of bad. Maybe you should hedge it by switching to 80/20 a few years before the 70/30 switch. You see where this is going. Suddenly we've arrived at the standard, mainstream notion of slowly increasing your allocation to bonds as you get closer to retirement.
Now, it's important to be aware of the costs as well as the benefits. By slowly allocating to bonds, you are also slowly reducing the expected return of your portfolio. But what that buys you is a slow decrease in variance over time. An increased ability to withstand downturns, that goes up in tandem with your vulnerability to downturns.
Pie, I'm not going to tell you that you personally have to allocate to bonds. You're clearly comfortable with a high level of risk. But this is the argument for it: over time, your ability to withstand risk goes down. It's prudent to lower your risk as your ability to withstand it decreases.
And I'm very uncomfortable with advising people in this thread to not invest in bonds at all. Sure, that's a thing you can do if you can deal with the risks due to a high income or not caring or maybe
needing to take higher risks in order to get your portfolio to where you want it... but it's not for everyone. Most people will find that a stock/bond portfolio, with the allocation to bonds increasing over time, works better for them as far as risk/return go.
