6. Ratio of Up vs. Down
FY1 EPS Estimate Revisions
Description of Factor:
This factor considers the analyst
revisions to 1-year forward EPS estimates over
the past twelve months.
Specifically, this factor is calculated by: (number of upward revisions
– number of downward revisions) divided by total number of estimates. Note that this factor does not consider the
size of the revisions, just the directional change of the revised estimates. The rationale behind this variable is the
expectation that stocks with more upward revisions than downward revisions will
exhibit earnings momentum and earnings surprise characteristics. We surmise that stocks which contain a high
value for this variable will outperform stocks with low or negative values for
this variable.
Analysis
Equal
Weighted: Looking at the
annualized average quintile return graph below, a step distribution is
exhibited. However, there is very little
spread between the returns of quintiles 3-5.
The spread between quintile 1 and 5 is quite small at 6.46%. Quintile 1 has the highest annualized average
return of 23.43% with a standard deviation of 16.80%, while quintile 2 exhibits
the lowest annualized average return of 16.97% and standard deviation of
13.97%. The average excess return of
quintile 1 is 3.76% and (2.06)% for quintile 5. The beta for quintile 1 is 1.10 with an R2
of 73%, while beta for quintile 5 is 0.91 with an R2 of 72%.
The annual
returns for a long-short strategy based on this factor are almost always
positive except for 2001 and 2002.
However, the losses in 2001 and 2002 were quite small at (0.38%) and
(3.07%) respectively. This result is
very important from a capital preservation perspective. It follows logically that the small expected
spread of 6.46% stated above is too minute to produce adequate long-term
capital appreciation with investments in portfolios with equity betas above 1.0
in each quintile. A notable achievement
of this strategy is a significant positive return in both 1999 and 2003 (16.44%
and 25.31% respectively). This is
notable because though the two markets were quite dissimilar, quintile 1 and 5
achieved the desired top-performing and bottom-performing positions
respectively in both years. However,
results in recent years are mixed as quintile 1 narrowly beat quintile 5 in
2000 and lost in 2001 and 2002, as discussed above. Perhaps the most intriguing aspect of this
strategy is the extremely low turnover ratios.
Quintile 1 turns over only 3.63% of its portfolio companies each month
while quintile 5 enjoys a 4.39% rate.
Value
Weighted: A value weighted
portfolio does not exhibit a downward step distribution, with the annualized
annual returns of quintile 4 eclipsing those of quintiles 2 and 3. The spread between quintile 1 and quintile 5
is only 4.19%. Quintile 1 has the
highest annualized average return at 21.21% and standard deviation of
14.16%. Quintile 5 has the second-lowest
average annual return of 17.02% and lowest standard deviation of 12.54%. The average excess return of quintile 1 is
1.72% and (2.06)% for quintile 5. The beta for quintile 1 is 1.02, while beta
for quintile 5 is 0.90.
A long-short
strategy based on this factor using value weights would produce a negative
return 7 times out of 16 sampled years and 2 out of the last 4 years. Only three times does quintile 1 achieve the
highest return and quintile 5 achieve the lowest return in the same year. Quintile 1 attains the highest return 5 times
and the lowest return once. Quintile 5
achieves the lowest return six times and the highest return twice.
Conclusion:
The equal weighted strategy based on this
variable performs much better than a value weighted strategy. This philosophy seems practical to implement
due to its low turnover ratios and limited downside. We are pleased with its effectiveness in two
up-markets (1999 and 2003) and its relatively safe returns in three turbulent
markets (2000, 2001, and 2002). While
there are some extremely positive returns, most notably in 2003, the majority
of the returns have been far too small to adequately satiate investors who are
seeking equity market returns. This
variable clearly exhibits a track record of solid results. Though we believe it is very promising when
used with an additional variable, we do not recommend a trading strategy based
on it alone.
