CFA 网站上有道题计算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. 我觉得是错的，应该是 (79.9-79.4)*20,000 是 决策价格和收盘价的差价。
