why the answer doesn't consider the first constriant?

嗨,从没放弃的小努力你好:
同学,这个你得根据前几个条件综合得出结论,第二个条件用到的。
•No investment in any security whose index weight is less than 0.010%
那就是不超过index的0.01%然后$4 billion (0.010% × $40 trillion).
•No position size that represents more than 10% of the security’s average daily trading volume (ADV) over the past 4 months
这个就是小于10%每日交易量,题目有说The smaller securities in permissible universe is allowed to trade about 1.5% of shares outstanding daily,所以每日的交易量是 $60 million (1.5% × $4 billion). 它的10%就是6million 。
•Maximum position size equal to the lesser of 10× the index weight or the index weight plus 100 bps
这个我上一个给你解释的一样,只是这个是知道了Maximum position size就是上面求出来的6million,然后再根据题目中的条件,反推出来AUM。0.01*10,然后6÷0.1=6 billion
