问题如下：
When the size of a position is doubled, what happens to (a) DV01, (b) duration, and (c) convexity?
选项：
解释：
DV01 doubles. The duration and convexity remain the same because they reflect percentage price changes.
讲义中dv01的计算公式不是这样的么？描述的是价格变动，和position有什么关系？

The ration anconvexity remain the same because they reflepercentage prichanges. 题目问当头寸变成原来的二倍的时候，01，ration和convexity会怎么变化？01会变成原来的二倍，ration和convexity不会发生变化。 △p也成为两倍，为什么不影响久期，这不就是久期的分子也为两倍了
