Vcusefor gauging tren in intrcompany risk taking.这道题易误选 A 说 T 银行的交易活动比 N 银行的风险更大，是想用表格第一行数据比较。V是 value risk，也就是一段时间内（在某个可能性下）最大损失数是多少。average ily V就是平均的每天的最大可能的损失。这道题目表格里面的数字意思就是2017 年平均来看，每天可能只有极小概率下是损失超过 11.3 million。但是不同银行之间，不能用 V来比较风险大小。因为每个银行的资产规模是不一样的。average ily V大的不一定损失的比例高。\"Vis not useful for assessing risk-taking activities between fferent companies\" 这个B是什么意思呢？
