How much time would it take for the stock portfolio to double in value if the rate of return is 9.0%? Use the rule of 70 to find the answer [just google it]. State the answer as a number with 2 decimals (for example, 13.02).
Ans 7.78 years
Time to double the value by Rule 70 = 70 / Annual rate of return
= 70 / 9.0
= 7.78 years
