What is the difference between capital asset pricing model and constant growth difference between capital asset pricing model and constant growth approach?

Answer 1

The Constant growth model does not address risk; it uses the current market price, as the reflection of the expected risk return preference of investor in marketplace, whereas CAPM consider the firm's risk, as reflected by beta, in determining required return or cost of ordinary share equity.Another difference is that when constant growth model is used to find the cost of ordinary share equity, it can easily be adjusted with flotation cost to find the cost of new ordinary share capital. whereas CAPM does not provide simple adjustment.Although CAPM Model has strong theoretical foundation, the ease of the calculation of the constant growth model justifies it use.
