Security returns
Select one:
a. are easy to predict accurately
b. cannot be described using a probability distribution
c. are random and have a continuous probability distribution
d. are random and have a discrete probability distribution
Answer: Option C is correct.
Security returns are random and have a continuous probability
distribution because it can take infinite number of values. For
example if the stock price moves from say $20 to $21, it can take
any value (between $20 & $21) like $20.1, $20.02, $20.000001
and so on.
Discrete probability distribution refers to the probability of
getting certain particular values like $20, $21, $22, but stock
prices do not move from one particular value to another.
