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 to 4 decimal places, e.g. 31.2125 and the 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%		43.0%		58.0%
Moderate		20%		23.0%		28.0%
Recession		55%		-13.0%		-23.0%
