Historical.


"Historical simulation is conceptually the simplest alternative method to the delta-normal. There is no assumption about how markets operate.
For any given portfolio held today, you calculate repeatedly its hypothetical value change as if it had been held for a one day period in the past, using the relevant market price changes and other market rate changes for each successive day.
At each step, you do a full valuation and calculate the ex-post or historical value changes over one day."
