Is
the market over-valued? In this week's Outside the Box, one of my favorite
global equity analyst's (and no stranger to regular readers), James Montier
of Societe Generale does some very interesting analysis on the European and
US markets and finds the number of stocks which make his list as possible for
being a "short" is at very high levels. This is a remarkable read and re-enforces
my view that we are in a "sell in May and go away" summer. This is really a
great Outside the Box. Enjoy.

Joining The Dark Side: Pirates, Spies and Short Sellers
By James Montier
It never ceases to amaze me that whenever a major corporate declines the short
sellers are suddenly painted as financial equivalents of psychopaths. This
is madness, rather than examining the exceptionally poor (and sometimes criminal)
decisions that the corporate itself took, the short sellers are hauled over
the coals.
As the New York Times recently reminded us, vilifying short sellers is nothing
new.
In the days when square-rigged galleons plied the spice route to the East,
the Dutch outlawed a band of rebels that they feared might plunder their
new-found riches.
The troublemakers were neither Barbary pirates nor Spanish spies -- they
were certain traders on the stock exchange in Amsterdam. Their offence: shorting
the shares of the Dutch East India Company, purportedly the first company
in the world to issue stock. Short sellers, who sell assets like stocks in
the hope that the price will fall, have been reviled ever since. England
banned them for much of the 18th and 19th centuries. Napoleon deemed them
enemies of the state. And Germany's last Kaiser enlisted them to attack American
markets (or so some Americans feared).
Jenny Anderson, NY Times, 30 April 2008
Last week, Albert Edwards took our equity weighting down to its minimum (see
Global Strategy Weekly, 8 May 2008), and my own bottom-up valuation work finds
little opportunity for investment at the moment (see Mind Matters, 28 January
2008). This suggests to me the main opportunities may lie on the short side
in the current market. So I guess I am joining the ranks of the dark side!
This remains anathema to analysts. As the chart below shows the percentage
of sell recommendations remains pathetically low. Indeed, the other day my
head of research showed me the second chart below showing that SG had the highest
percentage of sells amongst investment banks - it makes a pleasant change to
see SG at the top of a list on a positive note!


All of this got me to thinking about how to identify potential short candidates.
In keeping with my first note for SG (on limited information - see Mind Matters
3 December 2007, I want to focus on just a few key measures that stand out
to me as sources of poor underperformance.
Valuation
Most obviously (and unsurprisingly given my value bias) one of my primary
sources of underperformance has to be high valuation. There are myriad methods
of valuing a stock, of course. However, from the perspective of a short seller,
one of the most useful is price-to-sales.
Focusing upon high price-to-sales stocks allows us to hone in on story stocks
- those stocks that have lost all touch with reality. During periods of investor
enthusiasm there is often a marked tendency to move up the income statement
in order to try and keep valuation multiples 'low'. Indeed during the dotcom
years, things were valued on measures such as average revenue per user, clicks
and eyeballs!
Price-to-sales has always been one of my least favourite valuation measures
as it ignores profitability. Reductio ad absurdum demonstrates this clearly.
Imagine I set up a business selling £20 notes for £19, strangely
enough I will never make any money, my volume may well be enormous, but it
will always be profitless. But I won't care as long as the market values me
on price-to-sales.
I am not alone in pondering the insanity of this measure. One of my favourite
quotations of all time comes from Scott McNealy, the then CEO of Sun Microsystems:
But two years ago we were selling at 10 times revenues when we were at
$64. At 10 times revenues, to give you a 10-year payback, I have to pay you
100% of revenues for 10 straight years in dividends. That assumes I can get
that by my shareholders. That assumes I have zero cost of goods sold, which
is very hard for a computer company. That assumes zero expenses, which is
really hard with 39,000 employees. That assumes I pay no taxes, which is
very hard. And that assumes you pay no taxes on your dividends, which is
kind of illegal. And that assumes that with zero R&D for the next 10
years, I can maintain the current revenue run rate. Now, having done that,
would any of you like to buy my stock at $64? Do you realize how ridiculous
those basic assumptions are? You don't need any transparency. You don't need
any footnotes. What were you thinking?
Scott McNealy, Business Week, April 2002.
So whenever I hear people using price-to-sales to justify a stock I can't
help but think they are trying to hide something. However, as always I remain
a proponent of Evidence Based Investing, so the proof is in the pudding. Does
price-to-sales work as a strategy?
The chart below shows the performance of price-to-sales quintiles within Europe
over the period 1985-2007. Unsurprisingly, the cheapest stocks outperform the
most expensive stocks.

As a check on this particular valuation measure we regressed the returns from
a long short price-to-sales portfolio against the value minus growth returns
from MSCI Europe. A significant 'alpha' was found, so price-to-sales adds something
extra above and beyond price-to-book (as per the discussion above).
Financial Analysis
The second element of my short strategy is to examine the financial analysis
of the company. My outspoken criticism of analysts is sometimes taken as a
view that I think financial analysis is a waste of time. Nothing could be further
from the truth. I am driven to despair by the fact that analysts spend so long
wasting their time trying to do the impossible such as forecast earnings, but
I remain a fan of good solid fundamental-orientated research.
In the past I have advocated the use of the F score designed by Joseph Piotroski
as a simple but highly effective method of quantifying a fundamental approach.
In his original paper1, Piotroski applied a fundamental analysis screen to
help tell good value from value traps. In a subsequent paper2, he explored
whether a simple financial screen could enhance performance across a variety
of styles.
The screen Piotroski developed is a simple nine input accounting-based scoring
system. The table below shows the basic variables used in its calculation.
Effectively, Piotroski uses indicators based on three areas of financial analysis
in order to assess the likelihood of an improving fundamental backdrop.
Current operating profits and cash flow outturns obviously provide information
about the firm's ability to generate funds internally, and pay dividends. A
positive earnings trend is also suggestive of an improvement in the fundamental
performance of the firm. Earnings quality is also captured by looking at the
relationship between cash flows and reported earnings.
The next three measures are designed to measure changes in the capital structure
and general ability to meet debt-service obligations. If you like, these measures
assess the likelihood of bankruptcy and bring the balance sheet into the overall
score.
The last two elements of the overall F score are concerned with operating
efficiency. The variables used will be familiar to fans of Du Pont analysis
as they both come from traditional decomposition of ROA. Having assessed the
measures as per the table below, a firm's F score is simply the summation of
the various individual components (thus it is bounded between 0 and 9).

Piotroski examines the performance of this score in the US market over the
period 1972 to 2001. His main findings are shown in the chart below which maps
out raw returns by the overall F score. The average raw (market adjusted) return
for firms with low F scores (0-3) is 7.3% p.a. (-5.5%). Firms with medium F
scores (4-6) show raw (market adjusted) returns of 15.5% p.a. (3%). Those firms
with the highest F score (7-9) showed an average raw return (market adjusted)
of 21% p.a. (7.8%). This certainly shows that fundamental analysis can be a
source of alpha!

I find the European evidence to be similar. The average raw (market adjusted)
return for firms with low F scores (0-3) is 4.4% p.a. (-8%). Firms with medium
F scores (4-6) show raw (market adjusted) returns of 13.1% p.a. (0.5%). Those
firms with the highest F score (7-9) showed an average raw return (market adjusted)
of 15% p.a. (2.5%).

Piotroski also explores how his measure performs in the context of value and
growth stocks. As he notes:
It is very difficult for investors to systematically identify meaningfully
underpriced (overpriced) glamour firms (value firms), consistent with the
gains to financial statement analysis-based strategies corresponding to the
expected bias imbedded in each book-to-market portfolio. When FSCORE corresponds
to the expected performance of these firms (i.e. strong performance for glamour
and poor performance for value firms), each respective portfolio earns near
the market return. Effectively, financial signals confirming the expectations
that are likely already imbedded in price are assimilated into prices quickly,
while contrarian signals are (generally) discounted until future confirmatory
news is received. As a result, historical good news for glamour firms is
unable to generate excess returns, while historical good news for value firms
is a tradable opportunity, and vice-versa for trading opportunities conditional
on bad news.
This finding is confirmed by our European data as the chart below shows. Value
stocks with high F scores do particularly well (a raw return of over 20% p.a.,
some 4% better than the average value stock). However, growth stocks with low
F scores do particularly poorly (a raw return of -.7% p.a., some 9% worse than
the average growth stock).

In the context of our combing for short candidates, this implies we would
be best off looking at expensive stocks, so combining the first two components
should give a reasonable list of likely short candidates. However, I wish to
examine one more important factor before producing a final list.
Capital discipline
The final element of my hunt for potential shorts is a lack of capital discipline.
A survey conducted by McKinsey3 (at last something useful from them!) revealed
that corporates themselves knew that they weren't great at capital discipline.
The survey of "Corporate level executives" said "17 percent of the capital
invested by their companies went toward underperforming investment that should
be terminated and that 16 percent of their investments were a mistake to have
financed in the first place". Those working closer to the coal face (business
unit heads and frontline managers) thought that even more projects should never
have been approved (21% for each category!).
The survey also asked managers how accurate their forecasts were in various
areas of corporate investment such as the time taken to complete the project,
the impact on sales, costs etc. The results are shown in the chart below. Nearly
70% of the managers said they were too optimistic with respect to the time
the project would take to complete (evidence of the well known planning fallacy).
50% of the respondents said they were too optimistic about the impact the investment
would have on sales, and over 40% were too optimistic about the costs involved!

The survey also revealed that nearly 40% of the respondents said that managers "hide,
restrict, or misrepresent information" when submitting capital investment proposals!
The discouragement of dissent was also strongly noted, over 50% of those taking
part said it was important to avoid contradicting superiors (see Mind Matters,
5 March 2008).
Given these kind of views, it isn't shocking to note the findings of Cooper,
Gulen and Schill4. They explore the predictive power of total asset growth
for stock returns. The advantage of using total assets is, of course, that
it provides a comprehensive picture of overall investment/disinvestment.
In their US sample covering the period 1968-2003, Cooper et al find that firms
with low asset growth outperformed firms with high asset growth by an astounding
20% p.a. equally weighted. Even when controlling for market, size and style,
low asset growth firms outperformed high asset growth firms by 13% p.a.

The European evidence is also compelling. Over the period 1985 to 2007, we
find that low asset growth firms outperformed high asset growth firms by around
10% p.a. The bottom line is that capital discipline seems to be much neglected
by firms and investors alike.

Putting it all together
So we have covered three potential sources of short ideas. What happens if
we put them all together? The parameters I used to define my shorts were a
price-to-sales > 1, an F score of 3 or less, and total asset growth in double
digits.
This proved to be a powerful combination. Between 1985 and 2007 a portfolio
of such stocks rebalanced annually would have declined over 6% p.a. compared
to a market that was rising at the rate of 13% p.a. in Europe! Although I've
not shown the result below, similar findings were uncovered for the US as well.

The basket of shorts generated a negative alpha in excess of 20% p.a. with
a beta of 1.3. The basket witnessed absolute negative returns in 10 out of
22 years (45% of the time). Relative to the index it underperformed in 18 of
the 22 years (81% of the time).
The average stock selected by the model falls 8% p.a. (median 9.6% decline).
Some 60% of the screen picks witness absolute negative returns. Thus the model
also tends to pick a few stocks that do exceptionally well on the long side
- not good news for a short strategy. Hence, introducing the use of stop loss
can improve the performance of our short basket significantly. For instance,
putting a 20% stop loss in place raises the return from -6% p.a. to -13% p.a.


As regular readers will know I have described much of the period since late
2002 as being characterised by the dash to trash. This can clearly be seen
from the chart above. 2003 saw the shorts outperforming the market by 6%! A
feat repeated on a lesser scale in 2005 and 2006.
Despite the rocky road that this portfolio has suffered in recent years, I
believe that it remains a sound method of looking for shorts, and if we are
right that most of the opportunities are likely to be on the short side then
it could prove a useful tool in the times ahead.
Two final charts which echo one of the points I made at the outset of this
note are shown below. They illustrate the number of stocks that the screen
finds passing our criteria for being short candidates. In Europe, the average
over our sample is around 20 stocks per year. Running the screen now reveals
an all time high of almost 100 stocks passing the criteria.

In the US, the average number of stocks in our short basket is around 30.
Today, the screen finds no less than 174 stocks passing the criteria. This
clearly demonstrates to me the lack of value I alluded to at the start of this
note, and indeed suggests that the opportunities are now firmly on the short
side.
