Efektywność inwestycyjna portfela fundamentalnego na GPW w Warszawie

Abstract

This paper presents empirical tests of the relation between fundamental ratio (ROE, earning) and average return on the Warsaw Stock Exchange. The analysis examines a simple fundamental strategy. The test shows that when portfolios are formed on fundamental ratio, we observe abnormal return. Portfolio of high fundamental ratio outperforms the WIG index, generates a several dozen percent annual average return between 2002 and 2010, but susceptible to random factors.
