The index model has been estimated for stocks A and B with the following results:

RA $=0\mathrm{.}12+0\mathrm{.}690$RM $+$ eA

RB $=0\mathrm{.}04+1\mathrm{.}544$RM $+$ eB

$\backslash$sigma M $=0\mathrm{.}350$

$\backslash$sigma $($eA$)=0\mathrm{.}20$

$\backslash$sigma $($eB$)=0\mathrm{.}10$

What is the correlation coefficient between the two stocks?

Note: Round your answer to $4$ decimal places.
