A reader writes in, asking:
“I’m unsure when you would think about a weblog publish or related relating to money (CD’s, Brief Time period Treasuries, Cash Market, and so forth) however after studying and following your portfolio suggestions I’m curious in case you have opinions on money and the way a lot to maintain at any given time. I acknowledge all conditions are completely different however you’ve all the time performed a very good job of laying out the choices. My particular scenario is: not too long ago retired however my spouse is working for one more 2 years at which level we are going to each be retired.”
Firstly, I’m going to imagine for the sake of this text that you have already got a adequate emergency fund in place or don’t want an emergency fund. That’s, we’re assuming that you have already got a solution to cowl an sudden main expense with out incurring monetary catastrophe. The query is just: what a part of the non-emergency-fund portfolio needs to be invested in money?
And I’m additionally going to put aside the case of a “tactical” money allocation (i.e., holding money with the objective of investing it at simply the best time after a downturn), as a result of I’m not optimistic concerning the means to try this in any helpful method. As an alternative, I’m specializing in a static money allocation (i.e., holding money, with the intent of it being an ongoing a part of the allocation).
The next chart from PortfolioVisualizer reveals a $1,000,000 preliminary portfolio steadiness, neither including to nor spending from the portfolio over time. That is from January 1987 – January 2024. (January 1987 is the earliest date for which PortfolioVisualizer has “complete US bond market” information.)
The blue line represents a portfolio of 40% complete US inventory market, 20% complete worldwide inventory market, and 40% complete US bond market. The purple line represents of portfolio of 41% complete US inventory market, 20% complete worldwide inventory market, 29% complete US bond market, and 10% money.* (The 1% improve in inventory allocation is to maintain the general danger stage related.)
Right here’s the PortfolioVisualizer hyperlink, in case you need to study the numerical metrics or modify any variables by yourself.
To me, these look functionally the identical.
Now let’s have a look at a portfolio from which we’re spending. The next chart from PortfolioVisualizer reveals a $1,000,000 preliminary portfolio steadiness, utilizing a “4%” rule sort of spending technique (i.e., spending $40,000 within the first yr after which adjusting that spending upward with inflation). Once more, that is from January 1987 – January 2024. And the asset allocations are the identical as above. So this can be a fairly vital money allocation: 2.5 years value of spending (10% of the portfolio, when spending 4% within the first yr).
Right here’s the PortfolioVisualizer hyperlink, in case you need to study the numerical metrics or modify any variables by yourself.
Once more, they’re very related. And I believe we are able to not less than agree that, if the money did make a significant distinction, it was not in a helpful route.
And I get the same set of conclusions each time I run Monte Carlo simulations, whether or not by way of PortfolioVisualizer or RightCapital. Swapping out a piece of the bonds for money (after which adjusting the inventory allocation upward a smidge, to make an apples-to-apples comparability) is…high quality.
There’s nothing magical about money. No matter we are able to obtain by shifting a piece of the portfolio from bonds into money, we are able to most likely obtain by simply barely bumping up the general fixed-income allocation as a substitute. That is simply one other case of “Asset Allocation Isn’t Magic.” There are many completely different asset allocations that can get you to a given stage of danger and anticipated return, and any such allocation tends to be about nearly as good as one other.
Personally, I are likely to go for the only route (i.e., whichever allocation entails the fewest variety of complete funds or the least rebalancing).
However one related caveat is that, if money particularly, relative to different forms of fixed-income, helps you really feel higher about your portfolio (i.e., it makes dangerous days/months/years out there really feel much less hectic as a result of you recognize “I’ve acquired ___ years of money, able to faucet into, if wanted”) then that’s a compelling level in favor of a money holding. However from a purely monetary perspective, there doesn’t look like any particular want for an enormous money allocation.
