@QuantCourse7 жыл бұрын
Great question! If you are using daily returns, you can "scale" you VaR numbers by multiplying by the square root of time (VaR(95)*sqrt(n)). However, if you scale this for too long of a period, this has been shown to be quite an inaccurate assumption. Otherwise, you could use n-day returns and run VaR numbers on those returns. Or Monte-Carlo simulations!

use have to use square root rule of time and assume returns are IID. HS method cannot adjust to that as it makes no assumption about the shape of the distribution of the return curve.

@mickeydi1238 жыл бұрын
+Melié There are different models used in credit risk and market risk. In market risk, we mostly use VaR/CVaR and stress testing. In credit risk, we use models such as KMV, Altman's Z-score, O-score, Pr of default etc.. The key point is that in market risk, we try to model prices and returns. In credit risk, we model fluctuations in the value of assets, liabilities, cash flows etc.

thanks for the video, but you're calculating the VAR only based on history data. espacially in banking, there are much more ways how they're doing it. like a monte carlo simulation of the returns and based on that (expected value) they're calculating the VAR. I think the historical way has caused partially the banking crisis. some szenarios are not included in historical data, so running stress tests or other simulations are helpful!
