Got a nice note from S who writes:
Dear Uncle Bill,
Great description of dollar cost averaging. I'd heard the term before but didn't really know what it meant. What do you do if...you have the emergency money, you have the 401k maxed out, the Roth IRA maxed out, you have no debt, and you have cash that is only making 4.25% in the bank?
How do I get the equivalent of the asset allocation and dollar cost averaging for non tax sheltered money? I don't know enough (or enjoy it enough) to pick stocks myself.
I am 26.
Signed, S
Dear S,
First you shouldn't be asking questions about personal finance, you should be answering them. S is the poster child for what each young professional should be doing. S prompted me to go back and look at the section on weighted average dollar cost investing, or whatever you want to call it, and it is pretty good, if I do say so myself, so I decided to reprint it here. The whole discussion can be found in Category 12-Investments--All You Need To Know.
--For the foreseeable future (I was going to say five to ten years but that is way too long for you to contemplate right now) you will do what is known in the finance game as weighted dollar cost averaging investing. Bear with me-this is easy and boring investing. It has three components-
-asset allocation,
-regular contributions,
-time.
By setting up your 401(k) at work or the regular contributions to your IRA at Vanguard you already have an asset allocation-70% S&P 500 Index, 15% Small Cap Index and 15% International Index. Done. The first component is in place.
You have, by now, figured out the investment form at work or the Vanguard form for the IRA and settled on your regular contribution. It should be the maximum amount allowed. If you don’t know the maximum, ask. Your HR rep will know this and most certainly the Vanguard representative will know it, so ask. Our goal is always to keep things simple. Set up the transaction so the money will go directly to your investments out of either your paycheck or your bank account. This being done the second component is in place.
Now for time. This the most important element and one of which you have plenty of right now. The amounts invested each paycheck won’t seem like much at the beginning and they aren’t but they do add up. As Samuel Bronfmann said, “The first billion was tough, the second billion was inevitable.” This philosophy applies also to tens, hundreds and thousands of dollars. And then…
The market drops 30% tomorrow, or worse, stays there for five years. Again, you don’t care because you are investing 1) small amounts 2) over time 3) on a regular basis.
Dollar averaging works because if you buy into a market that is going up, your investment goes up with it. Dollar averaging works when markets go down because your investment buys more of the product when the market goes down. A simple example.
Every month for a year you invest $100 in the Vanguard S&P 500 Index. In January the Index is priced at $100 so you get 1 share. The market drops 30% in February so the Index is now selling at $70 so you now have 1.43 share plus the original 1 share for a total of 2.43 shares (good news) but the shares (the bad news) are worth only $170.10 (2.43 shares x $70=$170.10). Your total investment of $200 is now worth only $170.10. You are under water and ready to abandon the whole thing because…
In March the market dives to $60. You are too late to stop your investment and the idiots at Vanguard take your $100 and buy 1.667 shares so you now have a total of 4.0967 shares worth $245.80. You are out $54.20. Ok, lets speed this up.
The market falls to $55 in April, $50 in May, stays there in June. After half a year you have invested $600 and your investment shares total 9.9138 worth $495.69. You quit reading your statements. The market does nothing in July, August, and September. Your investment is now $900 but your shares are worth only $795.69.
The market comes back to $65 in October, $90 in November and a Santa Claus rally takes the market up to $130 in December. On New Years Eve you pull out your statement and determine that you have 19.3326 shares worth, at $130 a share, $2,513.24.
You invested $1,200 but have $2,513.24. The wonders of dollar cost averaging.
Now, most markets won’t go down 50% in one year and then come back for a 30% gain in the same year but over time such ups and downs do happen but we don’t care because of regression to the mean.--
Do the numbers, it works. And you, S, and the other S's out there really need to jump on this because you have the one asset that nobody else has--time. If you start this at thirty five you are way too late. Forty, glad you finally woke up but forget it. Fifty--pick out your room at the kid's house. Started early, this simple investment strategy will make you rich.
But what about the economy? What about wars? What about unemployment? What about AIDS? What about terrorism? What about Katrina? What about Republicans? What about Democrats?
Yeah, what about them? We've had all of them and more in the last 100 years and the market has averaged an annual return of 11%. The market is one tough character.
And S is way ahead of the curve. The rest of you better get going and try to catch up to S.
Tomorrow we will take a look at after tax investments.
