Portfolio managers pick stocks for their clients’ portfolios based on the investment objective of the portfolio and several other factors. one key consideration is each stock’s contribution to portfolio risk and its statistical relationship with the portfolio’s other stocks. based on your understanding of portfolio risk, which of the following statements are true? check all that apply. a) the market risk component of the total portfolio risk can be reduced by randomly adding stocks to the portfolio.
b) the risk in the portfolio will increase if more stocks that are negatively correlated with other stocks are added to the portfolio.
c) the portfolio's risk is not the weighted average of the individual stock standard deviations.
c) when returns on stock a increases, returns on stock b also increases. in general, this would mean that stocks a and b are positively correlated.
1. Because of the effects of diversification, the portfolio's risk is likely to be more than the average of all stocks' standard deviations FALSE, IT IS EXACTLY THE OPPOSITE, SINCE THE PORTFOLIO'S RISK IS LIKELY TO BE SMALLER DUE TO DIVERSIFICATION.
2. The unsystematic risk component of the total portfolio risk can be reduced by adding negatively correlated stocks to the portfolio TRUE, NEGATIVELY CORRELATED STOCKS ARE USED TO DECREASE A PORTFOLIO'S RISK
3. A portfolio's risk is likely to be smaller than the average of all stocks' standard deviations, because diversification lowers the portfolio's risk. TRUE, THIS STATEMENT IS JUST THE OPPOSITE OF STATEMENT 1 WHICH WAS FALSE.
First one is false because diversification reduces risk because it divides the risk amongst different securities. The portfolio risk will therefore be lower than the average of all stocks' standard deviations.
Second one is true because unsystematic risk is risk that will come with the type of stock or security purchased. It is usually referred to as diversifiable risk because using negatively correlated stocks can help diversify this risk.
Third one is True because the portfolio's risk when diversified is indeed likely to be smaller than the average of all stocks' standard deviation.
Fourth one is false because portfolio risk is reduced if stock that are negatively correlated are put into a portfolio because it means that when one stock is not doing so well, the other being negatively correlated, will be doing fine.
