Different sources define value investing differently.
Some say value investing is the investment philosophy that favors the
purchase of stocks that are currently selling at low price-to-book ratios
and have high dividend yields. Others say value investing is all about
buying stocks with low P/E ratios. You will even sometimes hear that value
investing has more to do with the balance sheet than the income statement.
In his 1992 letter to Berkshire Hathaway shareholders,
Warren Buffet wrote:
“We think the very term ‘value investing’ is redundant.
What is ‘investing’ if it is not the act of seeking value at least sufficient
to justify the amount paid? Consciously paying more for a stock than its
calculated value - in the hope that it can soon be sold for a still-higher
price - should be labeled speculation (which is neither illegal, immoral
nor - in our view - financially fattening).”
“Whether appropriate or not, the term ‘value investing’
is widely used. Typically, it connotes the purchase of stocks having attributes
such as a low ratio of price to book value, a low price-earnings ratio,
or a high dividend yield. Unfortunately, such characteristics, even if
they appear in combination, are far from determinative as to whether an
investor is indeed buying something for what it is worth and is therefore
truly operating on the principle of obtaining value in his investments.
Correspondingly, opposite characteristics - a high ratio of price to book
value, a high price-earnings ratio, and a low dividend yield - are in
no way inconsistent with a ‘value’ purchase.”
Buffett’s definition of “investing” is the best definition of value investing
there is. Value investing is purchasing a stock for less than its calculated
value.
Tenets of Value Investing
1) Each share of stock is an ownership interest in the
underlying business. A stock is not simply a piece of paper that can
be sold at a higher price on some future date. Stocks represent more
than just the right to receive future cash distributions from the business.
Economically, each share is an undivided interest in all corporate assets
(both tangible and intangible) – and ought to be valued as such.
2) A stock has an intrinsic value. A stock’s intrinsic
value is derived from the economic value of the underlying business.
3) The stock market is inefficient. Value investors
do not subscribe to the Efficient Market Hypothesis. They believe shares
frequently trade hands at prices above or below their intrinsic values.
Occasionally, the difference between the market price of a share and
the intrinsic value of that share is wide enough to permit profitable
investments. Benjamin Graham, the father of value investing, explained
the stock market’s inefficiency by employing a metaphor. His Mr. Market
metaphor is still referenced by value investors today:
“Imagine that in some private business you own a small
share that cost you $1,000. One of your partners, named Mr. Market,
is very obliging indeed. Every day he tells you what he thinks your
interest is worth and furthermore offers either to buy you out or sell
you an additional interest on that basis. Sometimes his idea of value
appears plausible and justified by business developments and prospects
as you know them. Often, on the other hand, Mr. Market lets his enthusiasm
or his fears run away with him, and the value he proposes seems to you
a little short of silly.”
4) Investing is most intelligent when it is most businesslike.
This is a quote from Benjamin Graham’s “The Intelligent Investor”. Warren
Buffett believes it is the single most important investing lesson he
was ever taught. Investors ought to treat investing with the seriousness
and studiousness they treat their chosen profession. An investor should
treat the shares he buys and sells as a shopkeeper would treat the merchandise
he deals in. He must not make commitments where his knowledge of the
“merchandise” is inadequate. Furthermore, he must not engage in any
investment operation unless “a reliable calculation shows that it has
a fair chance to yield a reasonable profit”.
5) A true investment requires a margin of safety. A
margin of safety may be provided by a firm’s working capital position,
past earnings performance, land assets, economic goodwill, or (most
commonly) a combination of some or all of the above. The margin of safety
is manifested in the difference between the quoted price and the intrinsic
value of the business. It absorbs all the damage caused by the investor’s
inevitable miscalculations. For this reason, the margin of safety must
be as wide as we humans are stupid (which is to say it ought to be a
veritable chasm). Buying dollar bills for ninety-five cents only works
if you know what you’re doing; buying dollar bills for forty-five cents
is likely to prove profitable even for mere mortals like us.
What Value Investing Is Not
Value investing is purchasing a stock for less than its
calculated value. Surprisingly, this fact alone separates value investing
from most other investment philosophies.
True (long-term) growth investors such as Phil Fisher
focus solely on the value of the business. They do not concern themselves
with the price paid, because they only wish to buy shares in businesses
that are truly extraordinary. They believe that the phenomenal growth
such businesses will experience over a great many years will allow them
to benefit from the wonders of compounding. If the business’ value compounds
fast enough, and the stock is held long enough, even a seemingly lofty
price will eventually be justified.
Some so-called value investors do consider relative prices.
They make decisions based on how the market is valuing other public companies
in the same industry and how the market is valuing each dollar of earnings
present in all businesses. In other words, they may choose to purchase
a stock simply because it appears cheap relative to its peers, or because
it is trading at a lower P/E ratio than the general market, even though
the P/E ratio may not appear particularly low in absolute or historical
terms.
Should such an approach be called value investing? I don’t
think so. It may be a perfectly valid investment philosophy, but it is
a different investment philosophy.
Value investing requires the calculation of an intrinsic
value that is independent of the market price. Techniques that are supported
solely (or primarily) on an empirical basis are not part of value investing.
The tenets set out by Graham and expanded by others (such as Warren Buffett)
form the foundation of a logical edifice.
Although there may be empirical support for techniques
within value investing, Graham founded a school of thought that is highly
logical. Correct reasoning is stressed over verifiable hypotheses; and
causal relationships are stressed over correlative relationships. Value
investing may be quantitative; but, it is arithmetically quantitative.
There is a clear (and pervasive) distinction between quantitative
fields of study that employ calculus and quantitative fields of study
that remain purely arithmetical. Value investing treats security analysis
as a purely arithmetical field of study. Graham and Buffett were both
known for having stronger natural mathematical abilities than most security
analysts, and yet both men stated that the use of higher math in security
analysis was a mistake. True value investing requires no more than basic
math skills.
Contrarian investing is sometimes thought of as a value
investing sect. In practice, those who call themselves value investors
and those who call themselves contrarian investors tend to buy very similar
stocks.
Let’s consider the case of David Dreman, author of “The
Contrarian Investor”. David Dreman is known as a contrarian investor.
In his case, it is an appropriate label, because of his keen interest
in behavioral finance. However, in most cases, the line separating the
value investor from the contrarian investor is fuzzy at best. Dreman’s
contrarian investing strategies are derived from three measures: price
to earnings, price to cash flow, and price to book value. These same measures
are closely associated with value investing and especially so-called Graham
and Dodd investing (a form of value investing named for Benjamin Graham
and David Dodd, the co-authors of “Security Analysis”).
Conclusions
Ultimately, value investing can only be defined as paying
less for a stock than its calculated value, where the method used to calculate
the value of the stock is truly independent of the stock market. Where
the intrinsic value is calculated using an analysis of discounted future
cash flows or of asset values, the resulting intrinsic value estimate
is independent of the stock market. But, a strategy that is based on simply
buying stocks that trade at low price-to-earnings, price-to-book, and
price-to-cash flow multiples relative to other stocks is not value investing.
Of course, these very strategies have proven quite effective in the past,
and will likely continue to work well in the future.
The magic formula devised by Joel Greenblatt is an example
of one such effective technique that will often result in portfolios that
resemble those constructed by true value investors. However, Joel Greenblatt’s
magic formula does not attempt to calculate the value of the stocks purchased.
So, while the magic formula may be effective, it isn’t true value investing.
Joel Greenblatt is himself a value investor, because he does calculate
the intrinsic value of the stocks he buys. Greenblatt wrote "The
Little Book That Beats The Market" for an audience of investors that
lacked either the ability or the inclination to value businesses.
You can not be a value investor unless you are willing
to calculate business values. To be a value investor, you don't have to
value the business precisely - but, you do have to value the business.
