Hi, guys

I am looking to build a code to generate 1000 random numbers given mean and standard deviation of a data set multiplied by an initial capital of X, then taking average, like 100 or 10 times, of the average so i get a sharper number as expected return after 1 year of investment.

This gives me the return for year 1, then i need to calculate the same, given the previous year capital, up to 30 years.

Someone can help me with this difficult task?

Thanks
