Current Attempt in Progress

To achieve a zero standard deviation for a portfolio, calculate the weights of stock A and stock B, assuming the correlation coefficient is 1. Use the following information. (Round intermediate calculations and final answers to 2 decimal places, e.g. 31.21%.)

State of the economy		Probability of occurrence		Expected return on stock A in this state		Expected return on stock B in this state
High growth		25%		42.0%		59.0%
Moderate growth		20%		21.0%		29.0%
Recession		55%		-9.0%		-19.0%

Weight of stock B		enter weight of stock B in percentages %
