What is the difference between a 01 measure and the corresponding duration measure?
解释：
The 01 measure shows the dollar change in the value of the portfolio for a small change in the term structure. The corresponding duration measure shows the percentage change in the value of the portfolio for a small change in the term structure. The 01 measure is a per basis point change. For the duration measure, interest rates are measured as decimals.
