Good news: There's a secret that can make you a better investor. You'll make more money, pay less in taxes, and spend less time stressing about the daily moves of your stocks.

Sounds great, right?

Even better, you already know this little secret. In fact, you learned it in the fourth grade. And despite its simplicity, it can give you a huge advantage over Wall Street pros -- because they all but ignore it.

What is it?

You won't believe how easy it is
The little secret that can truly make you a more successful investor and give you a leg up on Wall Street is an understanding of the principle of compounding. And before you scoff, realize that if all investors understood the principle of compounding, we'd act very differently when it comes to managing our portfolios. For example, we wouldn't:

  • Check our stock tickers hourly, daily, weekly, or even monthly.
  • Pay so much attention to shows like Mad Money that focus on short-term analysis.
  • Trade more than a few times each year.

It's sad to work in an industry that makes so much money by addicting investors to these bad habits. If I could change anything about the financial services industry, it would be to silence the noise and focus on the numbers.

Alas, that won't happen
The financial industry won't change, but that doesn't mean you have to play its game. And I'm not advising you to stop checking on your stocks; that's part of the fun of investing.

What I am advising, however, is to be aware of the fact that the serious money in the stock market is made by investors who have four things:

  1. Time.
  2. Patience.
  3. A commitment to adding new money on a regular basis.
  4. A portfolio of great stocks.

With those four elements in place, you will rarely trade and therefore rarely pay transaction costs or taxes on earnings. And because your earnings stay in the stock market, those earnings will have earnings, and those earnings will have earnings, and so on.

A better way
Shelby Davis, a man who was by no means a master stock picker or market timer, amassed a nearly $900 million fortune over his lifetime simply by buying shares of great companies and holding them indefinitely. That's a successful strategy you can replicate.

Let's say, for example, you invested $1,000 in the seven S&P 500 members with the lowest price-to-book ratios 10 years ago. Here's what you'd own, and what each of those $1,000 positions would be worth today:


Current Value

MEMC Electronic Materials (NYSE:WFR)


Quest Diagnostics (NYSE:DGX)


Laboratory Corp. of America (NYSE:LH)


Entergy (NYSE:ETR)


Lennar (NYSE:LEN)


Pulte Homes (NYSE:PHM)


Ford (NYSE:F)


Total annualized return


S&P 500 annualized return


This simple, lazy strategy of buying seven stocks and sitting tight 10 years ago would have helped you absolutely thrash the market. No stress -- no taxes; just market-beating results. You also could have done better by adding new money on a regular basis or reinvesting dividends.

The best way
Of course, you could have done even better by picking better stocks. And that's where our Motley Fool Stock Advisor investment service may be able to help you.
