Which of the following statements about correlation is correct?​ Group of answer choices ​If the returns from two stocks are perfectly positively correlated and the two stocks have equal variance, an equally weighted portfolio of the two stocks will have a variance, which is less than that of the individual stocks. ​Risk is reduced when negatively related stocks are combined to form portfolios as long as the correlation coefficient is not equal to -1. ​The weaker the positive correlation two stocks exhibit, the more risk can be reduced when they are combined in a portfolio. ​If a stock has a negative correlation with market, its systematic risk is more than the market risk. ​Stocks with no correlation will have minimum diversification benefits.

Risk is the risk of a decline in a bond's value due to an increase in interest rates. this risk is higher on bonds that have long maturities than on bonds that will mature in the near future. risk is the risk that a decline in interest rates will lead to a decline in income from a bond portfolio. this risk is obviously high on callable bonds. it is also high on short-term bonds because the shorter the bond's maturity, the fewer the years before the relatively high old-coupon bonds will be replaced with new low-coupon issues. which type of risk is more relevant to an investor depends on the investor's , which is the period of time an investor plans to hold a particular investment. longer maturity bonds have high risk but low risk, while higher coupon bonds have a higher level of risk and a lower level of risk. to account for the effects related to both a bond's maturity and coupon, many analysts focus on a measure called , which is the weighted average of the time it takes to receive each of the bond's cash flows. conceptual question: which of the following bonds would have the largest duration? a)10year-zero coupon bonds b)10year-7% annual coupon bonds c)10year-3% annual coupon bonds d)5year-3% annual coupon bonds e)3year-7% annual coupon bonds
