The Most Profitable S&P 500 Companies (Case Study)
A. Describe some
of the advantages and disadvantages of ROE as a me asure
of corporate profitability. What is a typical
level of ROE, and how does one know if the ROE reported by a given company
reflects an adequate return on investme nt?
B. Define the profit margin, total
asset turnover, and financial leverage components of ROE. Discuss the advantages and disadvantages of
each of these potential sources of high
ROE.
C. Based upon the findings reported
in Table 11.3, discuss the relation between P/E ratios and profit margins,
total asset turnover, and financial leverage.
In general, which component of ROE is the most useful indicator of the
firm’s ability to sustain high profit rates in the future?
CASE
STUDY SOLUTION
A. For successful large and small
firms in the United States
and Canada ,
ROE averages roughly 10 to 15% during a typical year. This average ROE is comprised of a typical
profit margin on sales revenue of roughly 5-10%, a standard total asset
turnover ratio of 1.0 time s, and a
common leverage ratio of roughly 2:1.
ROE is an attractive me asure
of firm performance because it shows the rate of profit earned on funds
committed to the enterprise by its owners, the stockholders. When ROE is at or above 15% per year, the
rate of profit is generally sufficient to compensate investors for the risk
involved with a typical business enterprise.
When ROE consistently falls far below 10% per year, profit rates are
generally insufficient to compensate investors for the risks undertaken. Of course, when business risk is
substantially higher than average, a comme nsurately
higher return is required. When business
risk is some what lower than average,
a some what below-average profit rate
is adequate.
This
naturally suggests an important question: How is it possible to know if
business profit rates in any given circumstance are sufficient to compensate
investors for the risks undertaken? The
answer to this difficult question turns out to be rather simple: just ask
current and potential shareholders and bondholders. While it is difficult to accurately assess
business risk, and the problem of accurately me asuring
profit rates is always vexing, shareholders and bondholders implicitly inform
manageme nt of their risk/return
assessme nt of the firm’s performance
on a daily basis. If performance is
above the minimum required, the firm’s bond and stock prices will rise; if performance
is below the minimum required, bond and stock prices will fall. For privately held companies, the market’s
risk/return assessme nt come s at infrequent intervals, such as when new bank
financing is required. If performance is
above the minimum required, bank financing will be easy to obtain; if
performance is below the minimum required, bank financing will be difficult or
impossible to procure. Therefore, as a
practical matter, firms must consistently earn a business profit rate or ROE of
at least 15% per year in order to grow and prosper. If ROE consistently falls below this level,
sources of financing tend to dry up and the firm withers and dies. If ROE consistently exceeds this level, new
debt and equity financing is easy to obtain, and growth by new and established
competitors is rapid.
Finally,
while ROE may indeed be the most useful accounting indicator of business
profits, other accounting data should also be used to compare profit rates
across different lines of business, companies, and industries. In particular, investors must be cautious in
evaluating companies that report lofty ROE, but only moderate profit margins
and low ROA.
B. When profit margins are high,
robust demand or stringent cost controls, or both, allow the firm to earn a
significant profit contribution. Holding
capital requireme nts constant, the
firm’s profit margin is a useful indicator of managerial efficiency in
responding to rapidly growing demand and/or effective me asures
of cost containme nt. However, rich profit margins do not
necessarily guarantee a high rate of return on stockholders’ equity. Despite high profit margins, firms in mining,
construction, heavy equipme nt
manufacturing, cable TV, and motion picture production often earn only modest
rates of return on equity because significant capital expenditures are required
before me aningful sales revenues can
be generated. Thus, it is vitally
important to consider the magnitude of capital requireme nts
when interpreting the size of profit margins for a firm or an industry.
Total
asset turnover is sales revenue divided by the book value of total assets. When total asset turnover is high, the firm
makes its investme nts work hard in
the sense of generating a large amount of sales volume . Grocery and apparel retailing are good
examples of industries where high rates of total asset turnover can allow
efficient firms to earn attractive rates of return on stockholders’ equity
despite modest profit margins.
Leverage
is often defined as the ratio of the book value of total assets divided by
stockholders’ equity. It reflects the
extent to which debt and preferred stock are used in addition to common stock
financing. Leverage is used to amplify firm
profit rates over the business cycle.
During economic booms, leverage can dramatically increase the firm’s
profit rate; during recessions and other economic contractions, leverage can
just as dramatically decrease realized rates of return, if not lead to
losses. Despite ordinary profit margins
and modest rates of total asset turnover, ROE in the automobile, financial
services and telecommunications industries can some time s benefit through use of a risky financial
strategy that employs significant leverage.
However, it is worth reme mbering
that a risky financial structure can lead to awe-inspiring profit rates during
economic expansions, such as that experienced during the mid-1990s, but it can
also lead to huge losses during economic contractions or recessions, such as
that experienced during 2003. In the
financial services sector, high rates of financial leverage can boost profits
during periods of declining interest rates, but cause extreme financial distress during period of rapidly
fluctuating interest rates.
C. Using a simple ordinary least
squares regression approach to investigating the P/E-profit ability relation,
there is no simple and obvious positive effect of ROE on P/E ratios. These results are perhaps surprising because
it is commonly perceived that ROE is the most attractive accounting me asure of the firm’s wise use of operating and
financial leverage. Perhaps the
distortions to ROE numbers caused by significant corporate restructuring in
recent years have reduced the utility of those numbers for investors.
A
high degree of correlation between P/E ratios and profit margins is clearly
evident for this sample of consistently profitable corporate giants found
within the S&P 500. The
statistically-significant slope coefficient in the simple P/E = f
(profit margin) relation suggests that investors more highly capitalize
reported earnings for high profit margin firms.
Neither total asset turnover nor financial leverage has a similarly
consistent and positive effect on P/E ratios.
Similarly, profit margins are the only component of ROE with a statistically
significant effect on P/E ratios in a multiple regression model approach. Apparently, investors tend to rely upon high
profit margins as useful indicators of the firm’s ability to sustain
above-average profits in the future.
