The below three graphs show probability density functions (PDF) of three different random variables Red, Green and Blue. Let P1 be the unknown price of a stock in one year. P1 is a random variable. Let P0=1, so the share price now is $1. This one dollar is a constant, it is not a variable.

Which of the below statements is NOT correct?

a. Red is log-normally distributed, and the mean is higher than the median.

b. Blue is a stock's gross discrete return (GDR), with a minimum value of zero.

c. Blue is a stock's future price (P1), with a minimum value of zero.

d. Green is a stock's continuously compounded return.

e. Red is a stock's log gross discrete return (LGDR), with a minimum value of negative one.
