Μιχάλης - Χριστόφορος Γκλεζάκος


Under the joint assumption that CAMP holds and capital markets are efficient, systematic risk is the
only priced factor. However a stream of literature casts coubt on the above assumption, suggesting that

negatively related to company capitalization value. However, after controlling for other firm-specific
factors, the observed effect remained strong only within the prortfolio of high (historical) earnings yield
