Quantitative Stock Selection Portable Alpha Gambo Audu Preston Brown Xiaoxi Li Vivek Sugavanam Wee Tang Yee 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 2 Final Screen Constituents Final screen combined technical and valueoriented factors: Current Yield/PE Dividend Payout Ratio Momentum Reversal Voom Room for improvement is available 3 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 4 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 1 EW Current Yield /PE Factor Monthly Return 2.00% 1.50% 1.00% In-Sample Out of Sample 0.50% 0.00% 1 2 3 4 5 -0.50% Fractiles Stdev. of EW Current Yield /PE Factor Monthly Return 10.00% 8.00% 6.00% 4.00% 2.00% 0.00% In-Sample Out of Sample 1 2 3 Fractiles 4 5 5 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). 6 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. EW Div.

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) 14 The Weighted Factor 2.00 1.50 1.00 0.50 0.00 1 2 3 4 5 -0.50 Fractile Cumulative Returns(%) vs Market Returns (%) Weighted Factor 5000.00 4500.00 4000.00 3500.00 3000.00 2500.00 2000.00 1500.00 Fractile 1 Fractile 2 Fractile 3 Fractile 4 Fractile 5 Market 1000.00 500.00 0.00 ec -8 9 ec -9 D 0 ec -9 D 1 ec -9 D 2 ec -9 D 3 ec -9 D 4 ec -9 D 5 ec -9 D 6 ec -9 D 7 ec -9 D 8 ec -9 D 9 ec -0 D 0 ec -0 D 1 ec -0 D 2 ec -0 D 3 ec -0 D 4 ec -0 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 2.50 D Monthly Returns (%) - EW, Weighted Factor D Returns 15 The Weighted Factor Volatility and Sharpe Ratio Standard Deviation(%) - EW, Weighted Factor Q5 has higher s than Q1, despite the fact that returns for Q5 are lower than for Q1 6.00 5.00 4.00 3.00 2.00 1.00 This fact is validated by the comparing Sharpe Ratios – Q1 SR > 0.35, Q5 SR < 0 0.00 1 2 3 4 5 Fractile Sharpe Ratio - EW, Weighted Factor 0.50 0.40 0.30 0.20 0.10 0.00 1 2 3 4 5 -0.10 -0.20 Fractile 16 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 17
