Agenda • Sorting method and attributes for screening • Diagnostics • Factor/portfolio selection • Optimization • Conclusion
Sorting MethodAttributes for Screening We used sorting method in stock selection: • Univariate Attributes • Dividend yield • Earning growth • Projected Earnings Growth • Projected P/E • ROE • Reinvestment Rate • Momentum (1mo., 1yr.) • Cash Flow to Price • Earnings to Price • Book to Price • Revenue Growth • Bivariate Attributes • BV/P and MCAP • Dividend yield and Earning growth • Dividend yield and Projected EY
Diagnostics Performance Measurement • Average return and excess returns over market and risk-free • % Periods > Market • % Periods with positive return • Average ranking score Consistency Measurement • Standard deviations of returns and excess returns • Year by year ranking score
Factor /Portfolio Selection Significant Attributes • CF/P • E/P • PPE • ROE • RIR • BV/P and MCAP • DY and PPE

Match market volatility and maximize return: Weight Weight (Top) (Bottom) BV/P and DY -0.20 0.32 CF/P 0.37 -0.20 E/P -0.02 0.00 PPE 0.43 0.07 ROE 0.38 0.11 RIR -0.20 -0.06 Optimization
Optimization In-sample performance: • Beat market by 0.96% per month on average. • Beat market 68.75% of the time. Out-of-sample test on 11-month data: • Beat market by 2.83% per month on average. • Beat market 72.73% of the time.
Conclusion • Significant attributes in selecting stocks include CF/P, E/P, PPE, ROE, RIR, and BV/P and dividend yield together. • In Korea, stock selection (by sorting method) can help improve performance. • One important finding is that top fractiles tend to have high correlations with one another; hence, we may need to use bottom fractiles to reduce volatility.
