Hi! pls help me not from books or any plagiarism etc. minimum 300 words.thank you!

You plan to simulate a portfolio of investments over a multiyear period, so for each investment (which could be a particular stock or bond, for example), you need to simulate the change in its value for each of the years.

1)How would you simulate these changes in a realistic way?

2)Would you base it on historical data?

3)What about correlations?

4)Do you think the changes for different investments in a particular year would be correlated?

5)Do you think changes for a particular investment in different years would be correlated?

6)Do you think correlations would play a significant role in your simulation in terms of realism?
