How to Know What Rate of Return to Expect from your Stocks: Part 1
F.A.S.T. Graphs
June 29, 2012
Introduction
We
believe there are two critical attributes that the prudent investor
should consider before investing in a company (stock). Furthermore,
these same two attributes can be used to calculate a reasonable
expectation of the future return the stock is capable of generating on
their behalf. These two attributes are valuation and the rate of change
of earnings growth. Valuation indicates whether or not the company’s
current earnings power compensates you for the risk you take, while the
company’s future rate of change of earnings growth will be the driver of
future returns.
We
believe these are very important concepts for prudent investors to
understand for several reasons. First of all, you can make an
investment at fair value into a low or slow growth company, and still
not generate a high rate of return. On the other hand, the risk
associated with achieving it is normally low. This is simply because
achieving a low rate of earnings growth is easier to do. Conversely, you
could overpay, perhaps even significantly so, for a very powerful or
fast grower and still make a high rate of return, because of the power
of compounding.
However,
by overpaying you are taking on more risk than you should for two
reasons. First of all, the probability of a company achieving a very
high rate of growth is very low, and second, longer term it’s virtually a
given that price will return to fair value. Therefore, the investor
will not be able to harvest the full measure of the company’s growth
achievement. More simply stated, the probability of a future PE
contraction is very high. The effect is a lower rate of return than
deserved, while illogically taking a higher level of risk than necessary
to obtain the lower return.
To
summarize, if a company grows fast enough, then future earnings growth
can overcome a high beginning valuation. However, the risk taken to
achieve it is amplified by the high valuation. Conversely, if you come
across an opportunity to buy a stock at a very low valuation, even a low
growth company, your return potential is greatly enhanced while
simultaneously your risk is greatly lessened.
On
the other hand, overpaying for a slow grower (for example, a typical
utility stock) destroys your return potential while simultaneously
turning what might normally be a low-risk investment into a high risk
investment. In the same vein, if you can find a slow grower that is
significantly undervalued, you could generate a high return and arguably
achieve it at very low risk.
Valuation Demystified
As
stated in our introduction, valuation is one of what we believe to be
the two most important attributes that investors should consider before
investing in a stock. Yet, fair valuation alone does not automatically
indicate a high future return or even an adequate one. In truth,
valuation is a relative concept that becomes relevant to future return
only when looked at in conjunction with future growth. Throughout this
report, we will illustrate that valuation unto itself is most relevant
in the context of current time. In other words, valuation itself
applies predominantly to current fundamentals. Consequently, we see
valuation more as a measurement of soundness than we do as a rate of
return expectation.
As
a result, both a moderately fast-growing stock and a very slow-growing
stock can command the same valuation in current time. However, given
fair valuation for both, the faster grower offers a higher future
return. This concept can apply to all classes of stocks to include
non-dividend paying stocks as well as dividend paying stocks (Later in
this article I will more clearly reveal this principle with specific
examples). The point I am stressing is that valuation is more related to
soundness than it is to future returns. Even more simply stated,
valuation is about prudent behavior and risk mitigation.
To
illustrate this more clearly, we are going to utilize the most common
valuation measurement, the PE ratio. But first and foremost, we want to
emphatically state that the PE ratio is more than a mere statistical
inference. Instead, our objective is to illuminate the idea that the PE
ratio is a relevant measurement of valuation that represents the
appropriate compensation for the amount of risk currently being
assumed. The key to understanding this is to recognize the PE ratio as a
measurement of the earnings yield the investment is offering.
To
put this into perspective, consider that the long-term average PE ratio
of the S&P 500 has been, depending on the time frame being
measured, somewhere between 14 to 16 times earnings (S&P 500 average
PE 14 - 16). Jeremy Siegel, professor of finance at the Wharton School
of the University of Pennsylvania has written that stocks have returned
an average of 6.5% to 7% per year, after inflation, over the last 200
years. For simplicity sake, we are going to hang our hats on the
historical average S&P 500 PE ratio of 15.
Now,
up to this point, the average PE ratio of 15 for the S&P 500 is
simply a statistic. However, a statistic is information, but information
alone is not wisdom. To our way of thinking, answering the important
question as to why a PE ratio of 15 is common over such a long period of
time, is more critical than simply knowing the number itself. In order
to accomplish this, let’s analyze what PE ratios of 14 - 16 translate
into in terms of rate of return calculations. What we discover is that a
PE ratio of 15 represents a reasonable and attractive rate of return of
approximately 6% to 7%, that has historically been achieved (the
long-term stock market average), and therefore logically considered
acceptable and achievable.
To
add clarity to this point, let’s actually calculate the rate of return
(earnings yield) that a PE of 14, 15 or 16 represents. To determine the
earnings yield, simply reverse the PE ratio (Price divided by Earnings)
and calculate the EP ratio (Earnings divided by Price). Therefore, we
learn that a PE ratio of 14 equals an earnings yield of 7.1%, a PE ratio
of 15 equals an earnings yield of 6.66% and finally a PE ratio of 16
equals an earnings yield of 6.25%. Therefore, we learn through wisdom,
that it is no coincidence that these calculations coincide almost
perfectly with Prof. Jeremy Siegel’s historical statistic of average
stock market returns of 6.5% to 7%.
In
other words, an average stock market PE of approximately 15 (14-16) is
rational and makes economic sense because it represents an appropriate
yield on investment, which is why it is so commonly applied to the
valuation of most stocks. However, for this to be relevant enough to be
considered wisdom, it needs to also practically apply in real world
circumstances. To practically apply, we must be able to see and measure
evidence that clearly shows that the average fair value PE ratio of 15
actually does manifest in reality.
Testing the Fair Value 15 PE Ratio Hypothesis
In order to test the fair value PE ratio of 15, we will utilize the earnings and price correlated Fundamentals Analyzer Software Tool - F.A.S.T. Graphs™. This powerful “tool to think with” utilizes widely accepted formulas
for valuing a business. Utilizing these formulas, appropriate
valuations in the form of PE ratios are calculated.
Interestingly,
these formulas tend to calculate the fair value PE ratio to be
approximately 15 for companies whose earnings growth has historically
averaged 3% to 15% per annum. Companies whose growth is below 3% will
calculate out at PE ratios slightly less than 15. For very fast growing
companies (above 15%), a different formula that calculates higher PE
ratios applies, and will be presented later. This supports the 200-year
6.5% to 7% yield that Prof. Jeremy Siegel reported (Remember, a PE of 15
equals an earnings yield of 6.66%).
Once
the fair value PE ratio is calculated, monthly closing stock prices are
overlaid onto the graphs in order to discover if there is a strong
price and earnings correlation. If the formulas are valid, then we
should see a very close association between earnings and stock price
relative to a PE ratio of 15 over time.
The following four earnings and price correlated F.A.S.T. Graphs™ illustrate how the market has historically valued companies that
possess varying growth rates that range within the 3% to 15% growth
category at a PE of 15. The reader should note that each of these
samples show that the calculated PE (the orange line) and the normal PE
historically applied by the market (dark blue line) are virtually the
same, or at least close.
SCANA Corp (SCG): A Low Growth Regulated Utility
Our
first example plots SCANA Corp. whose earnings growth rate has averaged
only 3.3% per annum. Here, we would like to remind the reader that our
position is that fair valuation is a function of the earnings yield that
“current earnings” represent. Consequently, purchasing a company
at fair valuation implies that the investor is making a sound financial
decision. However, as previously stated, this does not necessarily
guarantee a high future rate of return. As we will illustrate in Part 2,
that will be determined by the company’s future earnings growth rate.
The
orange line on the following graph represents our fair value PE ratio
of 15 applied to SCANA Corp.’s historical earnings since calendar year
1998. To be clear, every point on the orange line equals a PE ratio of 15.
The Graham Dodd Formula was used to calculate the fair value PE ratio
of 15 and is expressed to the right of the graph in orange letters - GDF
X 15. According to our thesis, if this truly is a fair value PE ratio,
when the stock price overlay is applied, then price should track the
orange line very closely over time.
Our
next graph overlays monthly closing stock prices with our orange
earnings justified valuation line. Moreover, two additional important
valuation metrics are also added. The light blue shaded area expresses
dividends paid out of earnings (the green shaded area). The dark blue
line represents our algorithm calculating the normal PE ratio that the
market has historically applied to this business over this time period.
Clearly,
we see that the black price line tracks the orange earnings justified
valuation line (PE = 15) almost perfectly. The normal PE ratio (14.4) is
also almost a perfect match indicating that the market has historically
appraised this company at approximately 15 times earnings.
Furthermore, during the short-term time periods when price temporarily
deviates from earnings, we see that it soon returns. Therefore, we
discover in this example that fair valuation exists any time the stock
is trading at a PE ratio of 15 or below. (Note: Once again, the rate of
return that this produces is a different matter that will be elaborated
on in part 2).
OGE Energy Corp. (OGE): Another Utility with Slightly Higher Growth
Our second example, OGE
Energy Corp, differs from our first only by virtue of the fact that its
earnings growth rate since 1998 has averaged over 5% per annum.
Nevertheless, we once again discover that the PE ratio of 15 represents a
strong proxy for this company’s valuation. During the short time
intervals when price deviates from fair value PE of 15, it doesn’t take
long for price to move back into alignment with earnings.
Furthermore,
during this time frame there have been almost no incidences of
overvaluation with either of our first two examples. However, in both
cases we see that when the PE ratio falls substantially below our PE 15
standard, the opportunity for higher rewards at significantly lower risk
clearly manifest.
Wolverine World Wide (WWW): A Faster Growing Global Marketer of Footwear
Our
third example, Wolverine World Wide, moves farther up the growth chain
with earnings averaging 9.4% per annum. Nevertheless, we once again see
the strong relationship and close correlation between stock price and
earnings over the long run. Perhaps due to the faster earnings growth
rate, we do see several periods where the company’s price earnings ratio
has deviated significantly above the 15 standard, indicating
overvaluation. Nevertheless, just as we saw with our first two examples,
stock price inevitably and soon moves back into alignment with
earnings.
Inter Parfums, Inc. (IPAR): Develops, Manufactures and Distributes Prestige Perfumes
Our
final example, Inter Parfums, Inc., is an above-average growing
small-cap that validates our PE 15 standard, but with a twist. Small
capitalization companies tend to carry greater risk than larger
capitalization companies. As a result, it is not uncommon to see, as we
do with Inter Parfums, Inc., an earnings and price correlated graphic
with wilder price swings.
On
the other hand, we believe the following graphic clearly validates the
thesis of fair valuation. The PE 15 principle continues to apply over
the long run. More directly stated, price does track earnings, albeit
with violently volatile price swings in between. But most importantly,
in spite of all the price gyrations, stock price continues to quickly
and inevitably revert to the fair value PE ratio mean of 15.
Summary and Conclusions
In
this Part 1 of this two-part series, the majority of our focus has been
on the principle of fair valuation, or as we like to call it - True
Worth™. Our contention is that by understanding and accepting the idea
that fair valuation is primarily a metric of soundness, it
simultaneously lays the foundation for determining future returns from a
common stock investment. However, as we will expand upon in Part 2,
valuation is a relative measurement. Therefore, when viewed in
isolation, it does not provide an accurate future return calculator.
In
order to calculate future returns within a reasonable degree of
accuracy, we must consider valuation as it relates to earnings growth.
In this Part 1, we have provided evidence that fair valuation calculates
out to be very similar for companies generating earnings growth of 3%
to 15% per year. Our thesis is that fair valuation is, first and
foremost, a function of a stock’s current earnings yield. This is why
companies with different earnings growth rates will command similar, if
not identical, current valuations. However, as we will develop in Part
2, thanks to the power of compounding, when growth becomes very fast
(above 15%) a higher valuation becomes justified.
But
perhaps most importantly, in Part 2 we intend to demonstrate how
investors in common stocks can utilize the principle of valuation in
conjunction with the company’s expected future earnings growth rate to
determine reasonable future rate of return expectations. We believe
these are critical components for investors to master. Because, when
valuation is understood and looked at in conjunction with future
earnings growth, risk assessments also become more clear and accurate.
Consequently, not only can investors have a better idea of what rate of
return they can expect, but they can also ascertain how much risk they
are taking to generate it. As a result, smarter, sounder and more
profitable buy, sell and hold decisions can be made.
