Stock Screen Parameters to Mimic Martin Zweig’s Investment Style

The below bullet points attempt to recreate Martin Zweig’s investment style using technical parameters that can automatically be screened.  These parameters are from an interpretation by Harry Domash, and were run using the MSN stock screener.  The text in italics explains how the parameter was defined in the screener.

1) Long Growth: Find companies with consistent sales and earnings growth.  Zweig says 15% is acceptable, but also gives examples of companies with over 30%

Parameter: 5-Year Annual EPS Growth Rate >= 15%
Parameter: 5-Year Revenue Growth >= 15%

2) Recent Growth: Find companies that are accelerating in growth instead of decelerating

Parameter: EPS Growth Qtr vs Qtr >= .75 * 5-Year Annual EPS Growth
Parameter: Revenue Growth Qtr vs Qtr >= .85 * 5-Year Annual Revenue Growth

3) Revenue vs Earnings: Find companies whose revenue growth doesnt greatly outpace the EPS growth, indicating shrinking profit margins.  On the other hand, EPS growth shouldn’t greatly outpace revenue growth, indicating profits are only coming from cost cutting, not from sales 

Parameter: 5-Year Annual EPS Growth Rate >= .75 * 5-Year Revenue Growth Rate
Parameter: 5-Year Revenue Growth Rate >= .75 * 5-Year Annual EPS Growth Rate

4) Value: Dont overpay or underpay.  A high P/E may signal the stock is overvalued, and a low P/E may signal that investors have low confidence in the company.  Zweig compares a companies P/E to the market to determine if it is over or under valued  (SoS Note: Perhaps comparing this to industry average would be a better interpretation, since certain industries command higher P/Es due to higher expectations of growth)

Parameter: P/E Ratio: Current <= 1.5 * S&P 500 Average P/E Ratio Current
Parameter: P/E Ratio: Current >= .4 * S&P 500 Average P/E Ratio Current

5) Winners: Find stocks that are winners, beating or keeping pace with the market.  The Relative Strength parameter compares a stock’s strength to that of the market, with a 50 meaning it is matching the market

Parameter: 6-month Relative Strength >= 50

6) Debt: Find companies that do not have a high level of debt

Parameter: Debt to Equity Ratio <= Industry Average Debt to Equity Ratio

7) Surprise: Find companies who haven’t recently disappointed the market with lower than expected earnings

Parameter: Recent Qtr Surprise % >= 0
