05.单选题 收藏 标记 纠错 Which of the following security market will result in highest arbitrage activity? A Market efficiency. B With no restrictions on short selling. C With high information-acquisition costs. 查看解析 上一题 下一题 正确答案B 您的答案C本题平均正确率:44% Contrast weak form, semi-strong form, strong form market efficiency难度:一般 推荐: 答案解析 Short selling helps in price discovery. Arbitrageurs benefit from pricing discrepancies (inefficiencies); therefore, arbitrage activity will be higher in markets with no restrictions on short selling. 问: B.是能够使市场更有效,所以应该是降低套利啊? C.是让信息获取的成本变高,即增加了信息不对等的可能性,才有机会套利啊? 所以我认为选C
