How Peter Lynch Earned 29% a Year for 13 years

March 14, 2014 | About:

When it comes to true investing legends, Peter Lynch is in a league of his own.

The former head of Fidelity's flagship Magellan Fund produced an annualized rate of return of 29.2% over his 13-year stint at the helm. This track record secured his place as the best mutual fund manager of all time.

So how did he do it? It's not as complicated as you think.

In his best-selling book, "One Up On Wall Street," Lynch revealed a powerful charting tool that greatly simplified his investment decisions.

Deemed the "Peter Lynch chart," this simple graph plots the stock price against its "earnings line," a theoretical price equal to 15 times the earnings per share.

When a stock traded well below it, he would buy. When it rose above it, he would sell.

Not exactly rocket science, is it?

The idea behind this technique is simple. Lynch (and most other successful money managers) believe that mature, stable companies are worth roughly 15 times their annual earnings. And over the last 135 years, this has proven to be the mean valuation of the S&P 500 index.

This is known as a the P/E ratio. It is merely the price of the stock divided by its earnings per share. The resulting multiple represents how many times you are paying for last year's earnings at today's stock price.

All things being equal, the lower the number the better. Low P/E ratios mean that you are getting more earnings for your investment dollar. And since most large cap stocks eventually trade for at least 15 times earnings, you are more likely to see your shares appreciate as they return to the 15 P/E level.

This simple idea was the basis of Lynch's investment approach and the reason he created his now famous chart.

The chart consists of only two lines. The first is the stock price. The second is the hypothetical stock price if it were to trade at a P/E of 15 (the earnings line). As Peter Lynch explained,

"A quick way to tell if a stock is overpriced is to compare the price line to the earnings line. If you bought familiar growth companies - such as Shoney's, The Limited, or Marriott - when the stock price fell well below the earnings line, and sold them when the stock price rose dramatically above it, the chances are you'd do pretty well."

Take Walgreens (WAG) for example. The Peter Lynch chart below shows a 10-year history of the stock price and the earnings line.

Most investors who bought the stock when it was trading above its earnings line experienced very small gains or even losses. However, buying Walgreens at any price below the earnings line led to sizable gains.

The same pattern can be found with almost any familiar U.S. stock. Oracle (NYSE:ORCL) and Wal-Mart (NYSE:WMT) are all shown below:

It is a well-known fact among investors that price follows earnings. Over multi-year periods, stock prices move in sync with changing company earnings.

But over the short term, stock prices are unpredictable. This creates valuable oportunities for savvy investors and makes the Peter Lynch chart a must-have/ Using the chart on any of the stocks above would have produced some very impressive gains.

Nice info!. But I guess it took some more effort, didn't it? I mean the P/E is well known as an indicator of overvalued stocks. Peter Lynch must be smarter than that, or is it reallt that simple?

Lynch's investment approach is really convincing, but I was wondering if you guys ever thought about diversifying your portfolio with other asset classes. My brother moved his IRA to a precious metals retirement account with Regal Assets and he was really happy with the result. http://www.regalassets.com/a/1320/

Fast graphs, http://www.fastgraphs.com/ , are the same thing with additional information.

Just joined this website. Seems like the site continues to promote low P/E ratios as an important investment factor. The market is very pricey currently, so I can see the reason for these articles. What does this site recommend if prices are too high? No income in bonds to be found. Would you consider a market short ETF if you anticipate the market to decline a little bit in the long-term? REITs are a great means of income, but even REITs are hitting their highs. Thanks.

Oconnellda, I agree with your conclusions completely, and I had the same questions you did. I do like market short ETFs, but these are not long-term investments. Sticking to the value theme, look at poor FCX, beaten down by copper and oil price collapses and beaten down even more today by a disappointing earnings report. It will hold up better in a bear market simply because its price has already crashed so low. And sooner or later there will be a rebound, commodity prices will rise, and FCX's stock price will boom upward. This is the kind of stock to look for in the current market.

Being that this thesis holds true, it makes further sense to look for lower P/E's too for faster payback and better ROI. Joel Greenblatt (Trades, Portfolio) wrote a book on this too, and he delivered over 30% a year in a 20 year period I believe. The key is consistent (i.e. stable) companies with these lower P/E ratios. Of course, buying them instead of high multiple stocks means you don't get Apple, Priceline, 3D Systems, or other high flyers.

The scheme is good, but I think it is somewhat out of date with respect to the progression Bitcoin, as we see below - the townsfolk different opinions and disagree, but how many emotions! Yeah, then there still will be, only time will tell, I personally for a fresh breeze! SkalikUA Change Tip of the Lord!

How does handle the new business dynamics coming into picture now a days?

Bhaveshnaik - 5 years ago    Report SPAM

With all due respect to the author and Peter Lynch, I think this idea - buy when PE is lower than 15 and sell when higher - is too simplistic and, quite frankly, not very useful if you are a serious investor.

I seriously doubt that Mr. Lynch looked at only this parameter to make his investment decisions; it is most likely one of the many factors he looks at. There are many great companies with higher PE ratios than 15 that make great investments based on their overall financial standing.

A better approach is to learn to calculate the Intrinsic Value of a business and buy a stock based on that value. With that, what you pay for a stock is based on what you expect as returns and how much risk you are willing to take for the given possibility of those returns. Once you have done that, perhaps this rule would be helpful on a more short-term basis to go in and out of the stock but it does not tell me exactly *when* I need to buy or sell. If you look at the charts, buying and selling at the crossover points won't give you great returns; it's when you buy near the lows and sell bear the highs. For these latter purposes, other technical indicators, such as MACD and Stochastics are probably more helpful.

@Bhaveshnaik Do you really believe that Peter Lynch doesn't know anything about calculating intrinsic values?

Obviously, you don't understand that THIS article is about using the Earnings Line -- and NOT about calculating intrinsic values -- which I'm sure Lynch knows all about.

@Wallstpig High flying stocks are for gamblers and traders, which is really a distinction without a difference.
