Sažetak


Ovaj rad pokušava da utvrdi kako da se srpski berzanski indeks, BELEXline, kombinuje sa četiri plemenita metala – zlatom, srebrom, platinom i paladijumom, kako bi se rizik sveo na minimum. U procesu konstruisanja portfolia koristimo teorijski koncept Markovica. Konkretno, prvo odredimo portfolio od pet instrumenata, zatim isključujemo onaj instrument sa najmanjim udelom i ponavljamo postupak dok ne dođemo do portfelja od dva instrumenta. Na ovaj način konstruišemo četiri portfolia od pet, četiri, tri i dva instrumenta. U portfoliu sa pet instrumenata, proces optimizacije je odredio nulti udeo srebra, jer srebro nosi najveći rizik od svih ostalih instrumenata portfolia. To, takođe, znači da portfolii sa pet i četiri sredstava imaju iste karakteristike. S druge strane, u portfoliu sa tri aktive, koji sadrži srpski indeks, zlato i platinu, nalazimo veće učešće platine u odnosu na portfolio sa pet sredstava, jer platina ima veću negativnu korelaciju sa BELEXlineom u odnosu na par zlato-BELEKSline. Portfolio sa dva instrumenta, koji uključuje samo indeks i zlato, ima veći rizik u iznosu od 5% i 4%, u odnosu na portfolie sa četiri i tri elementa. Opšti zaključak je da je portfolio sa tri instrumenta najbolji, jer ima nešto veći rizik od portfolia sa pet ili četiri instrumenata, ali ima niže transakcione troškove, jer uključuje samo tri instrumenta.
