答案和详解如下：

1、The continuously compounded rate of return that will generate a one-year holding period return of -6.5% is closest to:

A)   -6.3%.

B)   -6.7%.

C)   -6.1%

D)   -5.7%.

The correct answer was B)

Continuously compounded rate of return = ln(1 - 0.065) = -6.72%.

2、Given a holding period return of R, the continuously compounded rate of return is:

A)   e^R - 1.

B)   1/(1 - R).

C)   ln(1 + R).

D)   ln(1 - R) - 1.

The correct answer was C)    

This is the formula for the continuously compounded rate of return

3、If a stock decreases from $90 to $80, the continuously compounded rate of return for the period is:

A)   -0.1000.

B)   -0.1178.

C)   -0.1250.

D)   -0.2310.

The correct answer was B)

This is given by the natural logarithm of the new price divided by the old price; ln(80/90) = -0.1178.
