B)is expected to be the average of the expected return of the portfolio and VAR.

If the one-day value at risk of a portfolio is $50,000 at a 95 percent probability level, this means that we should expect that in one day out of:

A)
20 days, the portfolio will decline by $50,000 or more.
B)20 days, the portfolio will decline by $50,000 or less.
C)95 days, the portfolio will lose $50,000.
D)95 days, the portfolio will increase by $50,000 or more.

Answer and Explanation

This means that 5 out of 100 (or one out of 20) days, the value of the portfolio will experience a loss of $50,000 or more.
