Which of the following statements is CORRECT? a. A large portfolio of randomly selected stocks will always have a standard deviation of returns that is less than the standard deviation of a portfolio with fewer stocks, regardless of how the stocks in the smaller portfolio are selected. b. Diversifiable risk can be reduced by forming a large portfolio, but normally even highly-diversified portfolios are subject to market (or systematic) risk. C. A large portfolio of randomly selected stocks will have a standard deviation of returns that is greater than the standard deviation of a 1-stock portfolio if that one stock has a beta less than 1.0. d. A large portfolio of stocks whose betas are greater than 1.0 will have less market risk than a single stock with a beta = 0.8. e. If you add enough randomly selected stocks to a portfolio, you can completely eliminate all of the market risk from the portfolio.

Howard Millard recently opened a retail store specializing in hiking equipment and accessories. He was quite comfortable making decisions about the kinds of equipment he would stock in the store’s inventory, the décor of the retail space and his marketing strategy.An avid hiker since he was in his early teenage years and a competitive athlete, Howard knew the type of equipment that would be best to his target audience, and he knew that he needed to round out his merchandise mix with hats, shoes, energy drinks, snacks and other accessories. He was however, not certain about how to source the financing for this business venture. In speaking to a colleague he admitted that he personally did not possess the required financing to start such a business.To that end, he was cognizant of the fact that a sound business plan was necessary before approaching any potential lending institution or investor. This plan would provide details on the amount of money required and how he intends to utilize…

I 1. If news comes to the market that suggested that the world stock prices will encounter less variability (variance) for the coming years than in the past, what would this mean for an owner of a portfolio which is mostly composed of call and put options? A. This is great news less variability is less risk, which will help portfolio return B. It is unclear if this news will be beneficial or harmful to the portfolio C. This will have no effect on the portfolio as it is immunized from volatility. D. This will be bad news for the portfolio as it has many options within it and option values are higher when volatility is higher. The answer is D, as options increase in value with greater volatility and with less volatility the portfolio will surely be worthless money. O This is great news less variability is less risk, which will help portfolio return O It is unclear if this news will be beneficial or harmful to the portfolio This will have no effect on the portfolio as it is immunized from…
Which of the following(s) would be ways to reject the CAPM? a showing that there exist a stock with zero beta with the market earns an expected return higher than the risk free rate b showing that there exist a stock that earns higher expected return than the market c Showing that a portfolio consistently generates a negative alpha d Showing that a certain factor predicts expected return even after controlling for market beta
Select all that are true with respect to systematic and unsystematic risk. Group of answer choices Systematic risk is unimportant when estimating expected returns Unystematic risk is unimportant when estimating expected returns Total risk (Systematic + Unsystematic) is the key risk measure one needs to estimate expected returns In a well diversified portfolio, unsystematic risk is largely eliminated A key reason why the risk-return tradeoff is better for portfolios than in individual assets is because combining assets into portfolios reduces unsystematic risk A key reason why the risk-return tradeoff is better for portfolios than in individual assets is because combining assets into portfolios reduces systematic risk
an investment market, understanding the concept of undervalued and overvalued stocks is very important. Hence, a prudent investor must have good knowledge about Beta, Market Rate of Return and Risk Free Rate of Return. Required: a) Being an investor, critically analyse the conditions of undervalued and overvalued stocks
No matter how the stock price fluctuates, as long as it can provide a positive return, the risk of investing in stocks is low.If the concept of standard deviation is applied, is this true or false?
Diversification occurs when stocks with low correlations of returns are placed together in a portfolio. Identify at least one type of firm that might exhibit low correlations of returns with the overall stock market? Explain why the correlations of these firms are expected to be low.
Which of the following statement is true? (a) Correlation has no effect on the expected return of a portfolio. (b) As the correlation between two stocks increases, the volatility of the two-stock portfolio falls. (c) The correlation of a stock's return with itself is zero. (d) None of the above
Stock A has more systematic risk than stock B, stock B has more unsystematic risk than stock A, and it is unclear which stock (A or B) has more total risk. Both stock A and stock B have more systematic risk than the market. Which of the following assertions is most consistent with finance theory? Stock B would have a higher expected return than stock A and stock A would have a higher expected return than the market Stock A would have a higher expected return than stock B and stock A would have a higher expected return than the market Stock B would have a higher expected return than stock A and the market would have a higher expected return than stock A Stock A would have a higher expected return than stock B and the market would have a higher expected return than stock A Because it is unclear which stock (A or B) has more total risk, it is unclear which stock (A or B) would have a higher expected return
Which is true with regards to the systematic and unsystematic risk? To mitigate the unsystematic risk, an investor must choose two stocks that has a perfectly negative correlation when establishing ones portfolio of securities A portfolio with stocks that has high Sharpe ratios does not have both unsystematic and systematic risk because then generate excess returns The likes of inflation, recession, changes in interest rates are examples of market risk that can be reduced to zero by a portfolio that is fully diversified Systematic risk can be diversified by choosing stocks that has a small standard deviation but high correlation coefficient since these stocks are less riskier
