An index model regression applied to past monthly returns in Ford's stock price produces the following estimates, which are believed to be stable over time:

$r_F=0\mathrm{.}1\%+1\mathrm{.}1r_M$

If the market index subsequently rises by $8\mathrm{.}2\%$ and Ford's stock price rises by $8\%,$ what is the abnormal change in Ford's stock price? $($Negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to $2$ decimal places.$)$

Answer is complete but not entirely correct.
