B)
experience.
Variables are assumed to be normally distributed but may actually have non-normal
C)
distributions.

Question #5 of 12 Question ID: 1572821

Which of the following statements regarding the distribution of returns used for asset
pricing models is most accurate?

Normal distribution returns are used for asset pricing models because they will only
B)
allow the asset price to fall to zero.
Lognormal distribution returns are used for asset pricing models because they will

not result in an asset return of less than -100%.
