Why did you select the $30$ stocks you chose? $2.$ Which of your graphs looks the most like the "classic" graph that can be found in your textbook? Why? $3.$ Does the ordering of the stocks affect the portfolio standard deviation for the final $30-$stock portfolio? Why or why not? I $4.$ Other than the one$-$stock portfolio, the standard deviation of each portfolio $($Column S$)$is less than the average standard deviation of the stocks that comprise the portfolio $($Column R$)$Why is that? $5.$ In any of your graphs, does the standard deviation of the portfolio ever go up when you add a stock to it$?$ If so$,$ why? $6.$ Do you believe it is possible to put together an equally$-$weighted $30-$stock portfolio that has a lower standard deviation than the S&P $500?$ If so$,$ what attributes would you look for in each of the $30$ stocks? If not, why not?
