Answer:
(a) 0.04 or 4%
(b) 0.151 or 15.1%
Explanation:
(a) Cost of equity under DDM:
Re = (D1 + P) + g
where,
D1 = Dividend next year
P = Price of share
g = Growth rate
Re = [(0.30 + 1.04) ÷ $77] + 0.04
= 0.04
(b) cost of equity using the SML method:
Re = Rf + β (Rm - Rf)
= 6% + 1.30(13% - 6%)
= 0.06 + 1.30(0.07)
= 0.151 or 15.1%
