Abstrakt

Optymalizacja portfela jest głównym przedmiotem zainteresowania zarządzających portfelem. Dobór papierów wartościowych jest zależny od skłonności inwestora do podejmowania ryzyka. W niniejszym opracowaniu dokonano pomiaru zmian relacji ryzyko-zysk w miarę wzrostu liczby akcji w portfelu. Stworzono sześć różnych portfeli o liczbie akcji wynoszącej odpowiednio: 47, 95, 142, 190, 239 i 287 akcji. Dane dotyczące cen akcji i wolumenu obrotu były zbierane co tydzień z sześciu największych europejskich giełd papierów wartościowych (FTSE100, CAC40, FTSE MIB, IBEX35, DAX i MDAX). Do pomiaru poziomu ryzyka poszczególnych portfeli zastosowano wzór znany z teorii dywersyfikacji Markowitza (1952). Wyniki analizy pokazują, że ryzyko dywersyfikacji maleje dla portfeli o coraz większej ilości akcji (od 47 akcji do 287 akcji w portfelu). Średni ważony zwrot z portfela rośnie dla portfeli o większej liczbie akcji, co jest sprzeczne ze standardowymi teoriami portfela. Wyniki analizy mogą być przydatne dla inwestorów, którzy koncentrują się wyłącznie na największych europejskich giełdach papierów wartościowych.
