A New Investment Strategy with Economic Cycle Alternations Based on Residual Income Valuation Model: Empirical Results from Taiwan Stock Markets

The purpose of this research is an attempt to present a mixed model based on the residual income valuation model, where two new factors, business cycles and financial items, are added. We offer a practical investment opinion by which investors and fundamental analysts can either establish or adjust their portfolios if there is an effort made to reverse the present economic atmosphere due to the ongoing COVID-19 pandemic.We find that the items in financial reports don’t have the same impacts for different business cycles. However, tax has a significantly positive sign when economies are expanding or contracting.
