Stock Selection Approach
Identify short-term technical factors and fundamental
value-oriented factors
Combine factors in effort to produce excess returns
relative to the market without extreme volatility
The potential securities were constrained:
Public US-based companies
Top 500 companies by market capitalization
For final screen, companies with stock prices lower than $5 were
removed
In-sample 1990-1999, out-of-sample 2000-2005

Final Screen Constituents
Final screen combined technical and valueoriented factors:
Current Yield/PE
Dividend Payout Ratio
Momentum
Reversal
Voom
Room for improvement is available

Current Yield/PE
Introduction
Definition: Trailing current dividend yield over P/E ratio
We expect the factor to have a positive correlation with stock returns
If the indicator is high, the dividend is relatively high while the stock
price is relatively low, which means the stock price may be
undervalued
This ratio also shows how market participants evaluate the firm as
the P/E ratio reflect market expectations
FactSet code
FG_DIV_YLD(0) / FG_PE(0)
As fractiles increase we see
Declining returns
Higher standard deviation
Decreasing success at beating the benchmark
• Consistent across up and down markets
Higher volatility spikes massive return in fractile 5 occasionally (e.g.
10/99- 1/00) over fractile 1

Current Yield /PE
Return and Volatility
The declining returns through
the in-sample period show that
implementing a long/short
trading strategy by buying
quintile 1 and shorting quintile 5
is profitable. The out-of-sample
test is less clear, but shows the
same possibility
Both in-sample and out-ofsample, quintile 5 has a higher
standard deviation than quintile

Div. Payout Ratio
Introduction
Definition: Dividend per share over EPS.
The payout ratio provides an idea of how well earnings support
dividend payments.
• More mature companies tend to have a higher payout ratio.
• Low payout ratio means firms retain large portions of earnings to
support long-term growth.
FactSet code
FG_DIV_PAYOUT
As fractiles increase we see
Increasing returns
Higher standard deviation
Better success at beating the benchmark during up markets,
but not during down markets.
Higher volatility leads to large returns in fractile 5 occasionally
(e.g. 10/99 and 5/00).

Div. Payout Ratio
Return and Volatility
Increasing returns during the
in-sample period show that
implementing a long/short
trading strategy by buying
quintile 5 and shorting quintile 1
is profitable. The out-of-sample
test confirms this possibility.
Both in-sample and out-ofsample, quintile 5 has a higher
standard deviation than quintile
1, suggesting caution in using
this factor.

Reversal
Introduction
Definition: Price change over previous month
We expect previous month returns to reverse
Short-term momentum, not reversal takes place
• Stocks that gained in the previous month continue to gain
• Stocks that lost in the previous month continue to lose
FactSet code
FG_PRICE_CHANGE(-22,NOW)
As fractiles increase we see
Decreasing returns
Mildly increasing standard deviation
Decreasing proportion of positive returns
Decreasing proportion of benchmark-beating returns
• Consistent across up and down markets
Occasional volatility spikes (e.g. 1/99) when fifth fractile outperforms
massively

Voom (Volume x Momentum)
Introduction
Change in volume scaled by price magnitude and direction
1 month price change * (10 day Avg Vol / 3 month Avg Vol)
Hypothesis was that large Voom could predict strong positive or
negative trends
Reality was that Voom was much better at predicting sell-offs
• When Voom was high, stock price tended to drop in the following
month
Voom stayed consistent through both in and out of sample
periods, and across up and down markets
Need to employ a long/short strategy to create a portfolio that is
market neutral and is best positioned to have consistent returns
regardless of market direction

Monthly Returns 1990-1999

Returns are negative for the
first quintile, and then grow
positive.
4th quintile performed well with
low volatility
Equal weighted portfolio is
more consistent through time
Suggests that 1st quintile can
be used as a short strategy,
and a blend of the 4th and 5th
quintiles can be used for a long
strategy

The Weighted Factor
Introduction
Created from subjectively-weighted factors that were
determined to best describe portfolio. Weighted
factors include:
Momentum (Scored 4 for Quintile 1 & -2 for Quintile 5)
Reversal (5 for Quintile 1 & -5 for Quintile 5)
Voom (-4 for Quintile 1, 4 for Quintile 4 & 3 for Quintile
4)
Current Yield/PE (3 for Quintile 1 & -3 for Quintile 5)
Payout Ratio Score (5 for Quintile 5)

Observed trend shows that
annual returns decrease
uniformly from Q1 to
Q5,indicating that a longshort investing strategy
would be effective
Cumulative Returns for Q1 >
5000% over time period (in
and out of sample); cum.
returns for Q5 < 100% over
same period (mkt returns >
500% over the same period

Conclusion
Reversal and the weighted score formed the best
factors with monthly F1-F5 returns of over 2%
Investors should guard against volatility spikes with
options
Transactions costs may be high for some factors
Next steps
Incorporate forward-looking factors (e.g. FY2 P/E)
Optimize weights on weighted score
Examine interaction and macro variables as factors
