ECONOMY
AND MARKET ANALYSIS
Contd...
A
Framework for Fundamental
Analysis:
Under
either of these fundamental
approaches, an investor will obviously
have to work with
individual
company data. Does this mean
that the investor should
plunge into a study
of
company
data first and then consider
other factors such as the
industry within which
a
particular
company operates or the
state of the economy, or
should the reverse procedure
be
followed?
In fact, each of these
approaches is used by investors and
security analysts
when
doing
fundamental analysis. These approaches
are referred to as the
"top-down" approach
and
the "bottom-up" approach.
Bottom-Up
Approach to Fundamental
Analysis:
With
the bottom-up approach, investors
focus directly on a company's
basics, or
fundamentals.
Analysis of such information as
the company's products, its
competitive
position,
and its financial status leads to an
estimate of the company's earnings
potential
and,
ultimately, its value in
the, market.
Considerable
time and effort are required
to produce the type of
detailed financial
analysis
needed
to understand even relatively
small companies. The emphasis in
this approach is on
finding
companies with good long-term growth
prospects, and making accurate
earnings
estimates. To
organize this effort,
bottom-up fundamental research is
often brokers into
two
categories,
growth investing and value
investing.
Value
versus Growth:
Growth
stocks carry investor expectation of
above-average future growth in earnings
and
above-average
valuations as a result of high
price/earnings ratios. Investors
expect these
stocks to
perform well in the future,
and they are willing to pay
high multiples for
this
expected
growth. Recent examples
include Microsoft, Cisco Systems, and
Intel.
Value
stocks, on the other hand,
feature cheap assets and
strong balance sheets.
Value
investing
can be traced back to the value-investing
principles laid out by the
well-known
Benjamin
Graham, who coauthored a
famous book on security
analysis in the 1930s that
has
been
the foundation for many
subsequent security analysts.
Top-Down
Approach to Fundamental
Analysis:
The
top-down approach is the opposite of the
bottom-up approach. Investors begin
with the
economy
and the overall market,
considering such important
factors as interest rates
and
inflation.
The next consider future
industry prospects or sectors of
the economy that
are
likely
to do particularly well (particularly
poorly). Finally, having
decided that macro
factors
are favorable to investing, and
having determined which parts of
the overall
economy
are likely to perform well,
individual companies are
analyzed.
There
is no "right" answer to which of
these two approaches to
follow. However,
fundamental
analysts can be overwhelming in its
detail, and a structure is needed.
This text
takes
the position that the
better way to proceed in
fundamental analysis is the
top-down
approach:
first,
analyze the overall economy
and securities markets to determine if
now is a
91
Investment
Analysis & Portfolio Management
(FIN630)
VU
good
time to commit additional
funds to equities; second,
analyze industries and sectors
to
determine
which have the best
prospects for the future,
and finally analyze
individual
companies.
Thus,
the preferred order for
fundamental security analysis
used here is (1) the economy
and
market,
(2) the industry/sector, and
(3) The company .this
approaches is used in Part IV
,which
explains fundamentals security
analysis in detail. Here we
consider only the
justification
for this approach.
Economy/Market
Analysis:
It is
very important to access the
state of the economy and the
outlook for primary
variables
such
as corporate profits and interest rates.
Investors are heavily
influenced by these
variables
in making their every day
investment decisions. If a recession is
likely, or under
way,
stock prices will be heavily affected at
certain times during the
contraction.
Conversely,
if a strong economics expansion is
under way, stock prices will be
heavily
affected,
again at particular times during
the expansion. Thus, the
status of economic
activity
has a major impact on
overall stock prices. It is,
therefore, very important
for
investors
to access the state of the
economy and its implications
for the stock
market.
In
turn, the stock market
impacts each individual
investor. Investors cannot
very well go
against
market trends. If the
markets goes up (or down)
strongly, most stocks are
carried
along.
Company analysis is likely to be of
limited benefit in a year
such as 1974, when
the
stock
was down 25 percent. Conversely,
almost all investors did
well in 1995 regardless of
their
specific company analysis,
because the market was up
about 37 percent as
measured
by
the S & P 500.
Industry
/ Sector Analysis:
After
completing an analysis of the
economy and the over all
market, an investor can
decide
if it is a
favorable time to invest in
common stocks. If it is, the
next step should industry
or
sector
market analysis. King
identified an industry factor as
the second component
(after
market
movements) affecting the
variability in stock
returns.
Individual
companies and industries tend to respond to
general market movements,
but the
degree
of response can vary significantly.
Industries undergo significant
movements over
both
relatively short and relatively
long periods. Industries will be affected
to various
degrees
by recession and expansions. For
example, the heavy good
industries will be
severely
affected in recession. Consumer's goods
will probably be much less
affected
during
such a contractionary period.
During a severe inflationary
period such as the
late
1970s
and very early 1980s,
regulated industries such as
utilities were severely hurt
by their
inability
to pass along all price
increases. Finally, new
"hot" industries emerge from
time to
time
and enjoy spectacular growth. Examples
include synthetic fuels and
genetic
engineering.
Company
Analysis:
Although
the first two steps
are important and should be done in
the indicated order,
great
attention
and emphasis should be placed on company
analysis. Security analysts
are
typically
organized along industry
lines, but the reports
that they issue usually deal
with one
or
more specific companies.
The
bottom line for companies, as
far as most investors are
concerned, is earnings per share.
There
is a very close relationship between
earnings and stock prices, and for
this reason
92
Investment
Analysis & Portfolio Management
(FIN630)
VU
most
attention is paid to earnings. Dividends
after all are paid out of
earnings. The
dividends
paid by companies are closely tied to
earnings, but not
necessarily the
current
quarterly
or even annual
earnings.
A
number of factors are
important in analyzing a company.
However, because
investors
tend
to focus on earnings and dividends, we
need to understand the
relationship between
these
two variables and between
them and other variables. We also
need to consider the
possibilities
of forecasting earnings and
dividends.
Because
dividends are pad out of
earnings, we will concentrate on earnings
in our
discussion
of company analysis. Earnings
are the real key to
the fundamental analysis of
a
common
stock. A good understanding of earnings
is vital if an investor is to understand,
and
perform,
fundamental analysis.
Assessing
the Economy:
A
basic measure of the economy
is Gross Domestic Product (GDP),
defined as the market
value
of final goods and services produced by
an economy for some time
period. GDP
numbers
are prepared quarterly and
released a few weeks following
the end of the
quarter.
These
numbers constitute a basic
measure of the economic
health and strength of
the
economy.
We can
measure and observe GDP on both a
nominal and real basis. The
shaded areas
indicate
officials' periods of recession. Note the
ups and downs up to about 1990 and
the
long
upward movements from early
1991 into 2000, the greatest
economic expansion in US
history.
GDP
is revised twice in the
first three months after
its initial release. The
bureau of
Economic
Analysis initially releases an advance
estimate of quarterly GDP in the
first
month
following quarter end. In
the second month, it
provides a preliminary estimate, and
in
the
third month, it provides a
final estimate. The cycle
then starts over again. Over
the last
30+
years, the average revision of
GDP growth from the advance
to the final estimate
has
been
about two-third of a percentage
point. It should e noted
that almost 90 percent of
the
time
the advance estimate correctly predicts
the direction of quarterly change in
real GDP
growth.
What
Determines Aggregate Stock
Prices?
We
examined the variables that
are used to estimate the
intrinsic value of stocks with
the
dividend
discount model----dividends are
required rate of return----and with
the P/E ratio
model-----earnings
and the P/E ratio. The same
models apply to the
aggregate stock
market
as represented by
a market index such as the
S&P 500 index.
To
value the stock market
using the fundamental
analysis approach explained in chapter
10,
we
use as our foundation the
P/E ratio or multiplier approach, because
a majority of
investors
focus on earnings and P/E ratios.
Estimates of index earnings and the
earnings
multiplier
are used in equation 13-1.
As explained in chapter 10,
this model uses a
forward
P/E
ratio. We will use the S&P500
Index as our measure of the
stock market:
P0 = P0/E1×E1;
Where;
E1 = expected earnings on the S&P500
index
93
Investment
Analysis & Portfolio Management
(FIN630)
VU
P0/E1 = the forward
price earning ratio or
multiplier
We
consider each of these
variables in turn.
The
Earning Stream:
Estimating
earnings for purposes of
valuing the market is not
easy. The item of interest
is
the
earnings per share for a
market index or, in general
corporate profits after
taxes.
Corporate
profits are derived from
corporate sales, which in
turn are related to GDP.
A
detailed,
top down fundamental
analysis of the economy/market
would involve
estimating
each
of these variables, starting
with GDP, then corporate
sales, working down to
Corporate
earnings
before taxes, and finally to corporate
earnings after taxes. Each of these
steps
involves
various levels of
difficulty.
Looking
at real (inflation-adjusted) earnings
growth, we would expect it to
correlate closely
with
real GDP growth in the
long run and, in fact, of
the last 30 or so years, real
GDP
growth
has averaged about 3.1%
annually, whereas real earnings
for the S&P500 index
has
averaged
2.7% annually. Therefore,
when estimating real
earnings growth for the
future, the
best
guide may be expected real
GDP growth.
It is
reasonable to expect corporate
earnings to grow, on average, at about
the rate of the
economy
as a whole. However, for the
last years of the 20th century, operating earnings
per
share
for the S&P500 grew an
average of 10.2% per year
versus a rate of 5.56%
for
economic
growth. This simply
illustrates how difficult it is to
forecast earnings
accurately.
Extenuating
factors can cause some
divergences, for example,
share repurchases by firms;
any
increase the rate of earnings
growth relative to historical
rates.
Since
earnings have to be allocated
over fewer shares, as firm
repurchase shares,
earnings/share
increases. Estimate are that
this could add anywhere
from one-half to one
and
one-half% points to the
growth rate of real
earnings.
Which
Earnings Should We
Use?
Note
that an annual EPS for
the S&P500 index, as obtained at
www.spglobal.com,
can be
instructed
in various ways. For example
as of June 02, all four
quarters for 02 were
estimates-of
4 quarter total of $51.23.
One year ahead estimate
could involve the last
two
quarters
of 02 and the first two
quarters of 03. The past
years EPS numbers could be
taken
to be
the calendar year 01, or
the last two quarters of 01
and the first two quarters
of 02.
This
is further complicated by the
fact that for the
S&P500, S&P provides both
top-down
and
bottom up estimate and both "as reported"
estimates and operating estimates.
Furthermore,
S&P is now providing its
"core earnings" for the
S&P500 index, which
focuses on
companies after tax earnings
generated from their
Principal businesses. S&P
has
determined
that the primary reasons
the core earnings and as-reported
earnings differ are
pension
income and stock options
grant expenses, with the
treatment of pension gains
having
a very significant impact.
The differences between
these two numbers can
be
substantial.
The
Multiplier or P/E
ratio:
The
multiplier to be applied to the
earnings estimate is as important as the
earnings
estimate, and
often more so. Investors
sometimes mistakenly ignore the
multiplier and
94
Investment
Analysis & Portfolio Management
(FIN630)
VU
concentrate
only on the earnings estimate.
But earnings growth is not
always the leading
factor
in significant price changes in
the market. Instead, low
interest rates may lead to
high
P/E
ratios, which in turn may
account for the majority
price changes.
The
multiplier is more volatile
than the earnings component
and, therefore, it is even
more
difficult
to predict. Consider figure
13-3, which shows the P/E
ratio for S&P500
index,
since
1947. A trend line has
been included to show the
general upward swing of P/E
ratio
across
time. Also, 3 different
levels of P/Es are
identified with the bars
showing that at
different
times (the 60s and early
70s, the late 70s and
early 80s and the late
80s and the
early
90s), P/Es tended to cluster
together.
The
P/E ratio begin to rise in the
early 50s, reached a peak by
1960, and declined to the
16
to 18
area and remained around the
level through 1972. as
inflation heated up in 1973,
and
interest
rates rose, the multiplier
started to decline and by 1974 it was around 7,
less than
half
its previous level, a
drastic cut for such a
short time. Therefore, what
was considered
normal
(about17), in the 60s and
early 70s was not the
norm in the late 70a and
early 80's?
Most
investors did not estimate P/E
ratio this low for
this length of time. The
lesson from
this
analysis is obvious: investor
cannot simply extrapolate P/E
ratios, because
dramatic
changes
occur over time. Perhaps
the most that can be said is
that in the post war
period;
P/E
ratios of broadly based
indices have ranged from an
average of 7 to an average of
about
17.
For the S&P500 composite
index, the average P/E for
the period 1920 to 2001 was
approximately
17, and for the period 1950
to 2001 it was 17. The variation
however can be
dramatic.
The P/E ratio for the
S&P500 was 7.8 in 1978 and 32.6 in
1998. By 2000, the
P/E
had
decreased to 26.
P/E
ratios are generally
depressed when the interest
rates and the rates of
inflation are high,
such
as around 1980-81. P/E ratios
tend to be high when
inflation and interest rates
are low,
such
as the period of the mid
to-late-1990s, when P/E ratios
were at quite high levels
by
historical
standards. When earnings are
growing and the upward
profit trend appears to
be
sustainable,
investors are willing to
pay, more for today's
earnings. Think of the
following
relationships
between interest rates and P/E
ratios. In 1982, yields on
10- year treasury
bonds
were approximately 13%, and
the P/E ratio on the S&P500
index was around 11.
In
the
late 1990s interest tares
were around 65 and the P/E
ratio for 1998 was 32.6, and
for
1999,
30.5. In 2001, it was
46.
Investors
must be careful when using
P/E ratios to place them in the
proper context. P/E
ratios
can refer to historical data, an
average for the year, or
for a prospective period as
such
as
the year ahead. Obviously, a
significant difference can exist
between P/E ratios
calculated
using these different
definitions. Furthermore as noted
earlier, various
definitions
of
earnings for an index such
as the S&P500 are
available.
Using
the Business Cycle to Make Market
Forecasts:
Earlier
we established the idea that
certain composite indexes can be
helpful in forecasting
or
ascertaining the position of
the business cycle. However,
stock prices are one of
the
leading
indicators, tending to lead the
economy's turning points,
both peaks and
troughs.
What
is the investor who is
trying to forecast the
market to do? This leading
relationship
between
the stock prices and the
economy must be taken into
account in forecasting
likely
changes
in stock prices. Stock prices generally
decline in recessions, and the
steeper the
recession,
the steeper the decline.
However, investors need to
think about the
business
cycle's
turning points months before
they occur in order to have
a handle on the
turning
95
Investment
Analysis & Portfolio Management
(FIN630)
VU
points
in the stock market. If a
business cycle downturn
appears to be likely in the
future,
the
market will also be likely to turn
down some months ahead of
the economic
downturn.
We can be
somewhat more precise about
the leading role of the
stock prices. Because of
this
tendency
to lead the economy, the
total return on stocks ( on an annual
basis) could be
negative
(positive) in the years in which
the business cycle peaks(
bottoms). Stock prices
have
almost always rising as the
business cycle is approaching a
trough. These increases
have
been large, so that
investors do well during
this period. Furthermore,
stock prices often
remain
steady or even decline sharp rise as the
bottom is approached, a period of
steady
prices or
even a decline typically
occurs. The economy, of course, is
still moving a head
based
on the above analysis.
Based
on the above analysis:
1. If
the investor can recognize
the bottoming out of the
economy before it occurs,
a
market
price can be predicted, at least based on
past experience, before the
bottom is
hit.
In previous recessions since World
War II, the market started to rise
about half
way
between GDP starting to
decline and staring to grow
again.
2.
The market average gain
over the 12 months following
its bottom point at
about
36%.
3. As
the economy recovers, stock
prices may level off or even
decline. Therefore, a
second
significant movement in the
market may be predictable, again
based on past
experience.
4.
Based on the most recent
ten economic slumps in the
20th century, the
market P/E
usually
rises just before the end of
the slump. It then remains
roughly unchanged
over
the next year.
The
value of being able to analyze
business cycle turning
points as an aid to market
timing
is
obvious. Investors would
have increased their
returns, over the entire
sweep of US
economic
history, by switching into
cash before the business
cycle peaks and into
stock
before
the cycle reaches its
trough. It is particularly important to
switch into stocks
before
business
cycle troughs. However, as
our discussion in Chapter 11
about market timing
indicated,
the chances of timing the
market successfully on a regular
basis are small.
Using
the Fed's Model to Make Market
Forecasts:
The
Fed has developed a market
forecasting model that has
captured considerable attention
both
because of its relative
accuracy over some time
periods and because of its
simplicity.
This
model has a simple-premise---
because investors can and do easily
switch between
stocks and bonds,
based on the asset with
the higher yield, stock
returns will tend to restore
an
equilibrium relationship between
the two assets.
To
measure bond yields, the
Fed uses the yield on
10-year Treasuries. Of course,
this
number
can be observed on an updated basis every
day. To measure stock
yields, the
earnings
yield is used---earnings divided by
stock price, using the S
& P500 index. The
earnings
figure used is a forward
12-month earnings estimate based on
operating earnings.
Thus,
on January 1, 2004, we would
use an estimate of operating earnings
for the S&P500
Index
for the next 12 months
through the end of the year.
On April 1, 2004, we would
use
an estimate of
the next 12 month earnings
through April 1,
2005.
96
Investment
Analysis & Portfolio Management
(FIN630)
VU
The
Fed model can be used to
formulate decision rules in
the following ways:
·
When
the earnings yield on the
S&P500 is greater than the 10-year
Treasury yield,
stocks
are relatively
attractive.
·
When
the earnings yield is less
than the 10-year Treasury
yield, stocks are
relatively
unattractive.
An
alternative way to use the
Fed model is to estimate the
"fair value" level of the
S&P500
Index
and compare it to the actual current
index value.
·
If
the estimated fair value of
the market is greater than
the current level of
the
market,
stocks are undervalued.
·
If
the estimated fair value of
the market is less than
the current level of the
market,
stocks
are overvalued.
Finally,
note that the Fed
model implies that the
reciprocal of the yield on
10-year
Treasuries
is an estimate of the S&P500's
equilibrium P/E ratio. That
is,
Equilibrium
estimate of the S&P500 P/E Ratio =
1/Yield on 10-year treasuries
·
If
the S&P 500's actual P/E
ratio is less than the
estimated equilibrium P/E ratio,
equities
are relatively
attractive.
·
If
the S&P500's actual P/E
ratio is greater than the estimated
equilibrium P/E ration,
equities
are relatively
unattractive.
Potential
Problems with the Fed Model:
The
Fed Model has the great
virtue of simplicity and has
given some useful signals,
but it is
not
without its problems and
limitations, which are
important to note.
1. As
noted above, the model
implies a linear relationship
between the reciprocal of
the
Treasury
bond yield and the estimated
equilibrium P/E ratio. This
means that with a
Treasury
bond yield of 4 percent, the
predicted equilibrium P/E ratio is
25.
However,
with a Treasury bond yield
of 2 percent, predicted P/E is 50, and at
1
percent
it is 100. Therefore, it is highly
probable that the Fed
model is not as
reliable
when
interest rates are unusually
low, because the implied
linear relationship
overstates
the estimated equilibrium P/E
ratio.
2.
The model relies on the
estimated earnings for the S&P500
Index for the next
12
months.
There are different
estimates of this number,
involving top-down,
bottom-
up and S&P's
core earnings, and they are
revised often. Therefore, it is
difficult to
determine
exactly which number to use
at any given time.
3.
The model is derived by
assuming that the yield on
10-year treasuries can be
substituted
for the required rate of
return on equities and for
the return on equity
on
the
S&P500 Index. Historically, this
has often not been
the case.
In
conclusion, the Fed model
may offer some valuable
insights to investors trying
to
forecast
the future direction of the
stock market, but the
model should be used with
care. It
is by no
means a simple solution to
the forecasting problem, and
could easily mislead
investors,
particularly when interest
rates are unusually
low.
