Delta-normal value at risk (VaR, FRM T4-3)

[@kannushi]

"Sensitivity, ratio" in video is Macauley duration. Modified duration = Macauley duration/(1+ytm/2) for semiannual compounding. Perhaps in this video continuous compounding is used for the calculations but in such a case they just say "duration", not "modified duration", because Macauley and modified duration are equal.
