老師，請問Mock2下午33題答案解析這句話是不是寫錯了：Blue Star Fund participates 90% in the upside market and lags by only 10% in the downside market, creating an opportunity for more upside potential.
CFA 網(wǎng)站上有道題計算opportunity cost: Morrison has been working on executing a sell order to liquidate shares in Acme Industrials (ACME). The closing price on Tuesday was $79.90. Morrison received the order from Wright before the market open on Wednesday morning to sell 50,000 ACME shares with a day limit of $80.00. No part of the order is filled on Wednesday, and the stock closes the day at $79.60. On Thursday morning, Morrison instructed a new day order to sell the 50,000 shares at $79.50; 30,000 shares were sold at $79.50 per share, with resulting commissions and fees for the trade of $0.02 per share. Shares for ACME closed the day Thursday at a price of $79.40 per share. No further attempts were made to sell the unfilled 20,000 shares, which were canceled. 答案是 Opportunity cost = 50,000 – 30,000 = 20,000 × ($79.90 – $79.50) = $8,000. 我覺得是錯的，應該是 (79.9-79.4)*20,000 是 決策價格和收盤價的差價。
