$.$ If the model below is to give a reasonable valuation of a stock, which of the following is

not a valid assumption for the model?

Po $=$ FCFEo$(1+$ g$)$

ks $-$ g

a$.$ growth, g$,$ is negative

b$.$ there will be no growth, i$.$e$.,$ g is zero

c$.$ the growth rate exceeds the required rate of return

d$.$ the required return is exceptionally high $($e$.$ g$.$ ks $=30\%)$

e$.$ all of the above are workable assumptions and are valid the sense that the model

can be used even if they hold true
