当focus 在大盘股的时候，为什么long only的方法比其他方法更体现投资能力呢？比如针对大盘股的sector factor进行大量exposure的时候，感觉long short的方法更能体现投资能力呢
NO.PZ2019012201000039 问题如下 Matt makes the following statements about investing with long-only managers: Statement 1 A long-only portfolio puts a firm floor on how muinvestor cwin. Statement 2 A long-only portfolio generally allows for greater investment capacity thother approaches, particularly when using strategies thfocus on large-cstocks. Whiof Matt’s statements regarng investing with long-only managers is correct? Only Statement 1 Only Statement 2 Both Statement 1 anStatement 2 B is correct. 考点：Long/Short, Long Extension, AnMarket-neutral 解析：表述1错在投资者不是为收益设定底线，而是为损失设定了底线。因为股票价格可以跌到的最低水平为零，而上涨空间是无限的，因此，只做多的投资者最大可能损失的金额就等于股票的初始投资。 请问这道题Statement 2 讲的是什么啊？ 为什么正确？
