    Hi David,

    I remember in one of your videos you mentioned that there are 3 approaches to VaR

    Historical - historical data
    Monte Carlo - future data
    Parametric - no data

    My question is: for MC, the first step is to generate price paths using GBM. For that, while e is randomized, don't we need historical data to come up with the mean(drift) and variance(shock)?

    Could you kindly clarify?

    Thanks,
    Ying
