4. Steps 1)Specify list of factors 2)Univariate screens 3)Identify 5 fractiles for each factor 4)Choose significant portfolios 5)Optimize weights for portfolios with S&P500 volatility 6)Compare fixed weight strategy and dynamic weight strategy

5. Factor Returns

6. Identified factors  Factors (1m lagged) - Cashflow to Price - Debt to Equity - Market Capitalization - Price to Book

7. Factor Screen Cashflow to Price(5) : value weighted Debt to Equity(5) : value weighted Market Cap(1) : equal weighted Price to Book(5) : equal weighted

8. Optimization: fixed weights Form a portfolio with same volatility of S&P500

9. Dynamic weight strategy Add dummy variables 3 months S&P500 momentum In negative momentum, buy more portfolio with negative correlation with S&P500 (Price to book (5))

10. Optimization: dynamic weights Form a dynamic portfolio with same volatility of S&P500

11. Results

12. Conclusion Multi-factor model strategy outperforms universe return (e.g. S&P500) Dynamic weight strategy outperform fixed weight strategy Future consideration: Transaction cost should be considered to evaluate strategies
