Patrick currently holds the following portfolio. The composition of the portfolio and the characteristics of stocks included in the portfolio are as shown below.

w: weights; E(r): expected return; stdev: expected standard deviation; corr: the correlation coefficient between the returns of the two stocks in the portfolio.

Stocks	w	E(r)	stdev	corr
X	0.7	0.25	0.35	0.5
Y	0.3	0.15	0.25

Patrick is considering replacing Stock Y with Stock Z. Stock Z has the same expected return and standard deviation as Stock Y, but it has a higher correlation with Stock X.

How will the expected performance of Patricks portfolio change if he replaces Stock Y with Stock Z (after the replacement, Xs weight is still 0.7 and Zs weight is 0.3).
