Problem: Assume a portfolio with the following parameters: risk free rate (or drift) of 0.02 per year. Annualized standard deviations of returns of 25%. Initial portfolio value of $1,000,000,000. Create a Python program that calculates the 10%, one-month, expected tail loss. (Hint: recall that drift scales with time, but the volatility, or std deviation, or risk, scales with the square root of time.)
