A variable is currently 40
It follows a Markov process
Processis stationary (i.e. the parameters of the process do not change as we move through time)
At the end of 1 year the variable will have a normal probability distribution with mean 40 and standard deviation 10
Questions
What is the probability distribution of the stock price at the end of 2 years? ½ years? ¼ years? Dt years?
