<prompt> Umfanekiso uthatha ukuzwela kwempahla kubungozi obungaguquguquki owaziwa nangokuthi ubungozi obuhlelekile noma ubungozi bemakethe, okuvame ukumelwa yi-beta yenani β embonini yezezimali, kanye nenzuzo elindelwe yemakethe kanye nenzuzo elindelwe yempahla engekho engozini. I-CAPM ithatha uhlobo oluthile lwemisebenzi yokusetshenziswa lapho kuphela izikhathi zokuqala nezesibili zibalulekile, okungukuthi ubungozi bulinganiswa ngokuphambuka, isibonelo isisetshenziswa se-quadratic noma okunye ukubuyisa kwempahla okune-arbitrability distributions echazwe ngokuphelele yizikhathi ezimbili zokuqala isibonelo, ukusatshalaliswa okujwayelekile nezindleko zokuthengiselana zero ezidingekayo ukuze kuhlukaniswe ukuze kususwe yonke ingozi ye-idiosyncratic. Ngaphansi kwalezi zimo, i-CAPM ikhombisa ukuthi izindleko zemali ye-equity zinqunywa kuphela yi-beta. Naphezu kokuhluleka kokuhlolwa okuningi nokuhlolwa, i-CAPM iyaqhubeka nokubheka izinkinga eziningi  <response>: ingozi engahlukaniseki
