Abstract

A hosszú távon befektetők (például nyugdíjalapok, céldátum-eszközalapok és fiatal befektetők) számára fontos kérdés, hogy mennyire kockázatos hosszú távon részvényt tartani. Tanulmányunk a spektrális kockázati mértékeket helyezi középpontba, amelyek a vizsgált kitettségek lehetséges veszteségeit úgy átlagolják, hogy a nagyobb veszteségek nagyobb súlyt kapnak. A kitettséget a kockázatmentes bankbetét és a részvényárfolyam különbségének választva, a spektrális kockázatra tekinthetünk úgy, mint annak a mértékére, hogy a befektető átlagosan mennyire fogja azt bánni, hogy kockázatmentes bankbetét helyett részvényekbe fektetett. Tanulmányunkban illusztráljuk Bihary és szerzőtársai [2018] eredményeit, amelyek analitikusan megmutatták, hogy a részvénytartás spektrális kockázata kellően hosszú távon csökken, sőt negatív lesz. Ugyanakkor numerikusan azt tapasztaljuk, hogy az elviselhető kockázathoz legalább száz évet kell várnunk.* Journal of Economic Literature (JEL) kód: G11.
