Czy analiza sprawności zarządzania jest wystarczająca w kontekście doboru do portfela spółek spoza sektora finansowego? Analiza w latach 2001-2011

The purpose of the article is to check if restriction of analysed financial ratios to asset turnover ratios in the context of the stock selection, leads to find quantile portfolio that is better than any quantile portfolio constructed with financial ratios that describe each area of company activity. Companies are chosen to portfolios due to their position in the ranking that is constructed on the base of the chosen financial ratios. There are two rankings: the first one TMAI is built with all financial ratios, the second one TMAI_S is built with asset turnover ratios. Companies analysed in the study were quoted on the WSE between 2001 and 2011. The rankings and portfolios are constructed separately for each year. As a result, it can be stated that the portfolio 2 of the TMAI ranking as well as the portfolio 4 of the TMAI_S ranking systematically gave higher rate of return than the benchmark portfolio. Among that two portfolios, the portfolio 2 of the TMAI ranking gives higher geometric average return. When risk is analysed then it can be noticed that the portfolio 4 of the TMAI_S ranking has lower risk than the portfolio 2 of the TMAI ranking.
