Questions

Chаpter 11c: The Glоbаl Finаncial Crisis expоsed structural blind spоts in Value at Risk (VaR). Which of the following statements accurately describe these flaws?  (i) VaR only identifies the threshold where losses begin but completely ignores the severity of losses once that threshold is crossed. (ii) Under certain non-normal distributions, VaR can fail subadditivity, which mathematically implies that it can falsely penalize portfolio diversification. (iii) By relying heavily on recent historical data during stable periods, VaR limits dropped significantly, encouraging massive leverage right before the crash.
