Özet:

Purpose- The aim of this paper is to observe whether generating a portfolio having return more than index by investigating the return performance of index’s stocks and capital structure of firms in index in a certain period. The second aim of this paper is to provide portfolio diversification by using the method of this study. In this paper, firms and stocks on BIST-100 index are referenced for empirical study. Method- Stocks are chosen from BIST-100 index with regard to certain capital structure of firms in stocks, and second orderly stochastic dominance test is implemented on these stocks. Dominant stocks are defined to generate a portfolio after stochastic test and this portfolio’s return performance is compared to the index’-s return. Findings- The portfolio, whose stocks are filtered by a certain capital structure and then chosen by second orderly stochastic dominance test, has return performance better than index’s return. Conclusion- This paper is indicating that second orderly stochastic dominance method and capital structure is an important investigation to generate a portfolio having higher returns more than index’s.
