Systematic Equity Strategies: A Test Case Using Empirical Results from the Japan Equity Market

In an introductory paper, we explained Systematic Equity Strategies (SES) and how they can be used as factors in a risk model.  In this paper, we use data from the Japan equity markets to define seven new SES factors and study their empirical behavior.  Our findings illustrate the important role that these factors play in portfolio construction and risk management. Our study also shows problems associated with omitting these factors from a risk model, and explain why models that include SES risk factors should lead to improved portfolio risk forecasts.
