The Essence Of Stock Valuation Is Soundness, Not Rate Of Return

Introduction on Stock Valuation

When it comes to writing about investing in common stocks, my favorite theme typically revolves around valuation. In fact, I once had a reader dub me “Mr. Valuation.” Which, I might add was very flattering to me. Moreover, in the context of discussing valuation there are normally three concepts that are included. They are typically fair valuation, undervaluation or overvaluation.

Oh, but would it not be wonderful, if everything about valuation were that simple. In truth, the concept of valuation is much more complex than those three simple notions. Therefore, one of the primary objectives of this article is to broaden the reader’s perspectives and understandings of the incredibly important concept of valuation as it relates to investing in common stocks.

However, before I delve too deeply into this subject, I would like to offer these following positioning statements. Position number one, just because a stock is technically trading at fair value, does not necessarily mean that it is a good or attractive investment. Position number two, just because a stock is moderately overvalued, does not necessarily mean that it is a poor or unattractive investment. In truth, there are circumstances where a moderately overvalued stock is actually a much better investment than a stock that is fairly valued. The key, as will be discussed later, revolves around the potential growth of the respective company.

The reason that the above positioning statements are true and valid is because valuation is only one component of many relating to common stock investment returns. There are many other factors such as the earnings growth rate of the stock in question, past, present and future, that will impact the future total return. Whether a company pays a dividend or not, and the level of the dividend it pays, if it does pay one, is also very important.

Therefore, to summarize, valuation is but one important component of successful stock investing. Furthermore, I would argue that valuation is more relevant to the soundness of the investment than it is to the total return the investment is capable of achieving. This is why (and I will elaborate more on this later on in the article) two companies with vastly different growth rates can technically be fairly valued with the same PE ratio. However, the potential future performance of each can be materially different as a function of each respective company’s growth potential.

A Conceptual Definition Of Fair Value

If you look up the term fair value on sites such as Investopedia or Wikipedia and others, you will discover what I believe are vague and even somewhat esoteric definitions. Therefore, I believe it is important that I offer my own definition of fair value so that the reader can at least be cognizant of the precise concept I am referring to. To me, fair value, as it relates to common stock investments, is manifest when the current earnings yield provided by the company’s profits, compensate me for the risk I am taking by providing both a realistic and acceptable return on my invested capital.

When referencing my definition of fair value, it’s important to focus on the concept “current earnings yield.” There a couple reasons why I feel this is both rational and important. First of all, the current earnings of a given business are typically precisely known (reported earnings). Therefore, the calculation of the return that the current earnings are offering me can be accurately calculated. To clarify a little farther, after years of extensive research and experience, I have determined (or at least satisfied myself) that a PE ratio of 15 represents fair valuation for the majority of companies based on realistically achievable growth rates.

In addition to the fact that after examining thousands of companies over several decades, through the lens of the FAST Graphs™ (Fundamentals Analyzer Software Tool), I have observed that a 15 PE ratio represents historical fair value for earnings growth up to 15% per annum. There are other logical facts that also support a 15 PE. First, I believe that it is not a coincidence that the more than 200-year average PE ratio of the S&P 500 is 15. Second, this is a fact because I believe it also represents, and is consistent with, the long-term average return of 6% to7% that common stocks have traditionally delivered to investors.

This fact is supported by the reality that a 15 PE ratio represents an earnings yield (E/P) of 6.67%, or approximately 6% to 7%. My point being, that this is a rational and realistically achievable rate of return commonly found in the real world of stock investing. But I believe the most important point regarding this 15 PE concept rests on the notion of soundness, not rate of return. When the current earnings yield is between 6% and 7%, the investment is currently attractive whether or not the business grows, and almost regardless of the company’s rate of growth (up to a point – 15%).

Moreover, I will further offer and contend that there is a logical reason why the growth rates on what I am calling the average company are represented with a rather broad range. That range is from 0% earnings growth up to 15% earnings growth. This notion is built on the reality that any future stream of income, whether it grows or not, is worth a multiple of itself. To be as clear as possible, I am suggesting, based on years of experience, that the fair value multiple will often equate to a PE of 15 (earnings yield 6%-7%) with regards to publicly traded common stocks, and private businesses for that matter. Allow me to offer the following allegory in order to establish the veracity of this claim.

Let’s assume that you owned a business that was generating you $100,000 per year of net net net income. Furthermore, let’s assume that the $100,000 per year was both fixed and guaranteed. But let’s further assume that it was now time for you to retire and sell your business. The seminal question is, what price would you be willing to accept from me, if I were a potential buyer?

If I offered you $100,000 (PE = 1), you would (or at least should) without hesitation turn me down because you would know that in one year’s time you would be broke. However, if I offered you $1,500,000 (a PE of 15) you might consider selling. Because, if you invested the $1,500,000 and received a 6.67% return (the earnings yield from a PE of 15) your income would be $100,500 per year, or approximately what the business was earning you. This is the essence of why a PE of 15 is both rational, normal and most importantly, sound.

Although the above allegory assumes a business with no growth, it is important that the reader recognize that growth will have an impact on what future return the buyer of the business would earn. However, the principle of soundness is based on the idea that both buyer and seller are receiving an acceptable and realistic return of 6%-7% even with no future growth.

Additionally, it should also be recognized that there is always risk in achieving a given level of growth. The higher the expected growth, typically the riskier it would be to achieve it. On the other hand, once again, the soundness of the transaction on the seller’s behalf is somewhat predicated on the notion that one in the hand is worth more than two in the bush. Therefore, the 15 PE in reality properly compensates both the buyer and seller of the business on a current earnings yield basis, regardless of future growth.

The PE Ratio as a Valuation Guide Not an Absolute

To me, the proofs of any hypothesis, especially those regarding investing in stocks, are so to speak in the pudding. In other words, if the hypothesis has any validity at all, you should be able to demonstrate it through real world, real life examples. Stated more directly, you should be able to measure the fair valuation PE ratio by examining actual companies and the typical historical valuations that have been applied to them.

Therefore, I will provide eight examples of companies with different earnings growth rates to illustrate how accurately the normal PE ratio as a proxy for fair value applies to companies with growth rates from 0% to 15%. However, three of my examples will show growth above 15% in order to demonstrate that above this threshold, higher PE ratios reflecting fair valuation are justified.

But before I provide the examples, there is one additional concept of incredible importance that I believe must be understood. The valuation discussions that I have presented in the context of this article should be thought of as guidelines representing a reasonably accurate reflection of fair value. It is vitally important that the reader does not try to become too precise with these notions. Although I fervently believe that fair valuation is a vital component of a successful stock investing strategy, I also understand that it needs to be thought of as a rational valuation array.

Consequently, as I will elaborate on with each following example, the reader should be focused on objectively determining whether these valuation guidelines have relevance or not on each specific case. As a clue, if these notions of valuation that I have presented are reasonably accurate, then we should see a very strong correlation between earnings and a 15 PE ratio in the long-term stock price movements for any company with growth from 0% to 15%. However, I repeat that this should be thought of as guidelines and not as absolutes.

The Fair Value 15 PE Ratio For Growth From 0% to 15%

In order to illustrate the validity of the fair value PE ratio of 15 on companies growing between 0% to 15%, I will review the historical earnings and price correlation of several companies through the lens of the fundamentals analyzer software tool FAST Graphs™. I will start by illustrating a company with historical earnings growth of only 1.5% and progressively move to higher and higher earnings growth examples.

With the first five examples, the reader should clearly understand and recognize that the orange line on the graph plots the company’s earnings per share at precisely a PE ratio of 15. Therefore, no matter where you look on that graph, the orange line represents a fair value PE of 15. As a result, the monthly closing stock price line (the black line on the graph) should closely follow and correlate to the orange earnings justified valuation line. Notice that when the price goes above the line how quickly it returns, and how when the price falls below the orange line how quickly it returns.

If my hypothesis is correct, there should be a high correlation between the stock price and the earnings line. Consequently, as you review each of the examples ask yourselves these simple questions: Does the orange line (PE=15) represent a sound price to pay if I really wanted to invest in this company? What typically happens in the future when the price goes above the orange line, and conversely what typically happens when the price falls below the orange line? Let the facts answer these questions for you. The idea is to try to visually recognize whether or not the fair value 15 PE ratio makes sense, or represents soundness.

Of equal importance, the reader should recognize that the slope of the orange line equates to the company’s historical earnings growth rate. This is shown in the green box within the FAST FACTS presented at the right of the graph. Therefore, also recognize that the capital appreciation component will be highly correlated to the company’s growth rate, assuming that fair valuation at the beginning and end of the period being measured is in alignment.

For extra credit, you might also notice that in the long run the stock price always moves to the orange line, thereby generating the capital appreciation component of total return. The light blue shaded area on the graph depicts dividends (see the color-coded section of the FAST FACTS to the right of the graph). Consequently, it should be clear that total return will be the combination of the capital appreciation based on earnings growth, plus the additional contribution from dividends.

Consolidated Edison (ED) 1.5% Earnings Growth

My first example reviews Consolidated Edison, a utility stock with a history of earnings growth only averaging 1.5% per annum. The orange line on the graph represents our theoretical fair value PE ratio of 15. To be clear, anywhere the stock price (the black line) touches the orange line it’s trading at a PE ratio of 15. Of course, if it’s above the orange line the PE is higher than 15, and if the price is below the orange line it’s lower.

But the most important point to be gleaned from the graph is that it is clear that you should never be willing to pay more than the fair value PE of 15 to buy this stock. Moreover, it is also clear that the stock price has gravitated to and tracked the orange line (PE of 15) over the long run. With Consolidated Edison’s growth as low as it is, investors can’t afford to have any material drop in price, because it would easily destroy any capital appreciation they could expect. Moreover, it’s also clear that even if this company is bought at a fair value PE of 15, it would be unreasonable to expect capital appreciation to be greater than the 1.5% earnings growth the company generates.

Furthermore, by examining the blue shaded area representing dividends, relative to the green shaded area representing earnings, it should be clear that Consolidated Edison pays the majority of its profits (approximately 70%) to shareholders, in the form of dividends. Consequently, it should also be clear that Consolidated Edison’s attractiveness is based more on the consistency and level of its dividend than on capital appreciation. Also, we can see that dividends provide a significant portion of shareholder’s total return.
