Part 5: Best Investing Method Series

“All of us would be better investors if we just made fewer decisions.”
Daniel Kahneman (brainyquote) 

Welcome to Part 5, the final article in the Best Investing Method Series. The goal of this series is to show how simple smart investing is. The diversification strategy with asset classes is the closest approach the investor has to a “sure thing”. Not because you will never lose money, everyone loses money once in awhile, it is inevitable; you lose either to inflation (the same amount of dollars buys fewer goods and services) or to a drop in the investment markets.

Research shows that it is exceedingly difficult to beat the returns of the overall market long term. It is also quite unlikely you can time the market and get in at the absolute bottom and out at the top. A Vanguard study found that the more an investor jumps in and out of the market, the lower their overall returns.

Is Timing the Market the Way to Boost Returns?

Timing the market seems like the way to go. Buy in at the bottom and sell at the top, right? Certainly, this is preferable, but impossible. The perfect market timer will definitely beat the market returns according to Bodie, Kane, and Marcus’ classic Investments text, beating the 9.57 percent average stock return (1926-2009) by 6.7 percent for an annual return of 16.27 percent.

The problem with the “perfect market timer” is that she does not exist. It’s impossible to get in at the bottom and out at the top all of the time.

More times than not, the market timer trades too much, pays too much in fees, and sports lower overall returns than the investor who stays the course and invests with an asset classes diversification approach.

Market timing is great, but nearly impossible to implement.

Lump Sum Investing is Impractical and Stressful

In researching this article, I came across several studies advocating the advantage of lump sum investing over dollar cost averaging. Historically, the market goes up more years than it declines, so taking a lump sum and investing it all at once in the early stages of an increasing market, usually out performs dollar cost averaging.

If this is the case, investors should take the amount of money they would invest during a year or two and invest it all at once.

There are a few problems with lump sum investing, most investors need to invest regular amounts periodically because they don’t have a lump sum to invest.

If you did have a lump sum to invest, how would you feel putting $10,000 into the market this week and watch the value decrease during the next market decline? If history is any guide, during the next five years, there will be a negative return in the stock markets in one of the upcoming years. Markets go up and down and after four years of increasing market returns, some time in the future, the markets will decline.

Psychology matters in investing. The behavioral finance concept, loss aversion, shows that investors feel a loss more strongly than they appreciate a gain. An investor who drops a lump sum into an investment and then watches the value plummet will usually feel horrible.

For psychological and practical reasons, lump sum investing is difficult to pull off.

Dollar Cost Averaging is the Way to Buy Low and Sell High

Burton G. Malkiel, author of the iconic A Random Walk Down Wall Street states; “Dollar-cost averaging can be a useful, though controversial, technique to reduce the risk of stock and bond investment. Rebalancing can reduce risk and, in some circumstances, increase investment returns.”

Dollar cost averaging means investing in the markets with a specific amount of money at regular intervals. If you are investing in your workplace retirement account and have $400 transferred from each paycheck into a 401(k), then you are dollar cost averaging. By dollar cost averaging and regular rebalancing of your portfolio (going back to the original asset allocation), you are automatically buying more shares when prices are low and fewer at higher prices.

Here’s how dollar cost averaging works:

Invest $400 each month into Vanguard Total World Stock Index Fund (VTWSX). (I’m not recommending investing only in a stock fund. Although, you could have a completely diversified portfolio with just 2 funds. This international stock index fund and a diversified bond fund.)

In June, 2008 VTWSX was priced at $18.18 and your $400 bought 22.00 shares.

In November, 2013 VTWSX was priced at $23.72 and your $400 bought 16.86 shares.

You bought fewer shares when the price was $23.72 than you did at the lower price of $18.18. Thus, you bought move low priced shares and fewer shares at the higher price. A systematic strategy to buy low.

Reinvest all dividends and capital gains and along with buying more shares when prices are low, you’re avoiding the possibility of “going all in” at the wrong time. Thus, your risk is reduced.

Even if you don’t have a workplace retirement account, you can open a Roth IRA and complete the paperwork to have a specific amount transferred into the account every month.

Dollar cost averaging  is great for several reasons:

1. When the money is transferred automatically, you learn to live without spending it and your wealth is growing and compounding.

2. You avoid the possibility of putting all your money into the market before a big decline.

3. Your future finances are growing and you’re reducing the psychological fear of running out of money when you’re old.

 The Takeaway

Investing doesn’t have to be complicated or scary. You don’t have to pay someone to invest your money for you. Spend a bit of time learning the investing basics and start now. Figure out your risk tolerance, choose a few index funds, and have part of your income directed into your investment or retirement account to secure the future. It’s easy and you’ll sleep better knowing your future will be secure.

  1. Since I primarily invest in mutual funds, I would like to think I am buying low and selling high. Many of my funds are index funds and I dollar cost aaveraged into the funds.

  2. @Krantcents-If you dollar cost averaged into the funds when you invested, you probably bought more shares when prices were lower and fewer shares at lofty prices.

  3. I like how it all comes down to math sometimes. Dollar cost averaging can be a nice low maintenance approach to buy low and sell high!

  4. Hi Bryce, I think the most difficult part of this whole investing path is patience. It’s tough to believe that if you just stay the course over the long term, you can amass at least a million dollars or more if you start young enough.
    @Squirrelers-So true, the math of dollar cost averaging and compounding of returns answers the question, “How to build wealth with investing?”

  5. I agree, timing the market to perfection is near enough impossible. I think if you can get in at a low level (not the bottom) and sell at a high level (near the bubble) you’re doing ok as an investor. I would however love it if I could buy at the lowest market levels and then sell at the highest, I wonder if anyone’s achieved this. Great post Ms Friedberg, keep them coming.

    • @Nick-In response to your question, “I wonder if anyone’s ever bought at the bottom and sold at the top?” If anyone has achieved this miraculous feat, they are not sharing their secret with the public! :) On another note, if you can get close enough to buying at the near bottom and selling near the top, you’re doing well!
