第2题
Consider a bank that wants to have an amount of capital so that it can absorb unexpected losses corresponding to a firm-wide VAR at the 1% level. It measures firm-wide VAR by adding up the VARs for market risk, operational risk, and credit risk. There is a risk that the bank has too little capital because ().
A.It does not take into account the correlations among risks.
B.It ignores risks that are not market, operational, or credit risks.
C.It mistakenly uses VAR to measure operational risk because operational risks that matter are rare events.
D.It is meaningless to add VARs.
第3题
Which of the following correctly describe the similarities between operational VAR and market VAR? I. Both VARs, when used for regulatory capital measurement, need to be validated against actual loss experience. II. Both are built on data (market prices for market VAR and operational loss data for operational VAR) that are readily available. III. Both are modeled based on a normal distribution. IV. Extreme value theory can be used to model extreme losses at the tail of the distribution for both operational and market VAR.()
A.I and IV
B.I, II, and III
C.I, II, and IV
D.II, III, and IV
