I need help with this scenario.

I have $200,000 that I want to invest in stock. I need a diverse portfolio with at least 3 stocks. Compute the final rate of return on the stock portfolio using the start date of 7/8/20 and the as of date of 8/21/20. Why did the stocks change? Address the quality of stock and the company, risk, return, and diversification. Would bonds or mutual funds be a good investment for a portfolio?
