最近在準備考試
解歷屆試題中
其中有三題不太會 不知道這裡詢問版友是否適合
如果有觸犯我會刪除 不過還是希望版友能幫忙
1.假設市場預期報酬率16%,無風險利率為8%,而市場報酬率的標準差為20%.
假設你有100萬,而限定只能投資於市場與風險資產.
(1)什麼樣的投資組合可以達到預期報酬率14%?
(2)這個投資組合的B(beta值)值為何?
(3)這個投資組合的標準差為何?
2.假設在市場均衡的狀態下,某人擁有一B值為2支股票,
已知此股票之要求報酬率為15%且市場組合報酬率為10%.
若市場組合報酬率提高13%且無風險利率不變,則此股票之報酬率為何?
3.已知A B C 三股票之B值各為0.9 1.1 1.6
某人有100萬元投資於此三股票及
無風險資產,並希望得到一個和市
場組合同樣風險水準的投資組合.
若已知某人各投資10萬元於A B兩股票,
試問各應投資多少錢於c股票及風險資產?
