Previous question:Suppose a portfolio has an exposure of +50 to a one basis-point increase in the five-year Treasury rate in Table 13.1, an exposure of -100 to a one-basis-point increase in the ten-year Treasury rate in Table 13.1, and no other exposures.
Using Table 13.2, calculate the standard deviation of the daily change in the portfolio in the previous question based on its exposure to the first two factors.

解释:
Using Table 13.2, the standard deviation is
(14.152 × 20. 92 + 4.912 × 29.452 )1/2= 329.19
(14.152 × 20. 92 + 4.912 × 29.452 )1/2= 329.19 不明白为什么算标准差 把第一问的exposure给放进来???
