Using the CAPM model, assuming a risk$-$free rate of $1\%$ and a expected market return of $10\%,$ choose $4$ stocks of your choice and calculate the expected return of each stock. Additionally, assuming that the $4$ stocks make up your portfolio and have a weighting of $10\%$ for the $1$st stock, $20\%$ for the $2$nd stock, $30\%$ for the $3$rd stock, and $40\%$ for the $4$th stock, what is the Beta and the expected return of the portfolio?

use companies that arent apple$/$microsoft$/$telsa or amazon. THANK YOU
