First, let’s establish the ground rules. I’m talking about retirees exclusively, NOT people in their working years.
How much would a retiree have to have, invested exclusively in the S&P 500, to be able to not be affected by the periodic market downturns? Remember, the investments will be needed for their income during a retirement that, for many, is likely to last two or even three decades. In fact, even if less is needed during the early years of retirement, then people invariably need a great deal more when senior care, up to and including nursing home care, is, if not inevitable, then at least highly likely.
There is a controversial rule of thumb which suggests that an annual withdrawal of 4% of one’s assets is a reasonable amount… some, including me, think it can be more, some don’t. But bear in mind that the commonly accepted growth of the S&P 500 of 10% or more does NOT account for periodic withdrawals, nor of the compounding that this growth assumes.
So, what do you need invested in the S&P in order to maintain an annual withdrawal needed for life’s expenses, as well as conserving your assets to pay for that nursing home? One million? Two million? That’s only $40-80K per year, at the 4% rate… but when there’s a 20 or 30% drop in the market lasting 18 months (not a rare occurrence), maintaining that withdrawal rate shoots that apocryphal 10% annual return to hell. You can’t just depend on the dividend yield, which is a lousy 1.7% or so… that’s part of the overall yield, as well. Sustaining a flat withdrawal rate through a market downturn negatively affects future earnings, and inflation just makes the situation worse.
Yes, it all works if you live at an economic level Best described as ‘sparingly low’, which, except for a very few people, is far below what they may have hoped for, in retirement. Very few people have anything close to $1M invested at retirement, and no matter how it is invested, they are not going to yield even the 4% rule-of-thumb amount, let alone have enough in reserve to pay for a decent nursing home in their old age.
So, what’s the smart thing to do? Invest exclusively in an index fund whose assets (assuming the fund is weighted by market cap, like the S&P 500) are highly volatile? Remember, in retirement, the long term performance of an investment over multiple years to multiple decades is the LEAST important factor… what matters is 1) whether you can reliably withdraw enough each year to meet living expenses, and 2) how well insulated you are from periodic downturns. Yes, there are SOME stocks in the S&P which can provide the necessary characteristics for a retiree… but not all of them… not by a long shot.
You can’t take it with you… at best, you can hope to live comfortably for the remainder of your life, and have enough to pay for the expensive care you’ll likely need for a while before you shuffle off this mortal coil… and if you are VERY lucky, leave enough behind for your grandchildren’s education.
