Which of the following statements about cost-of-equity estimation is most correct?

The CAPM approach is always superior to the DCF approach.

The risk premium used in the debt-cost-plus-risk-premium approach is the same as the risk premium used in the CAPM approach.

Because the CAPM and DCF approaches use market data, they provide precise cost-of-equity estimates.

The debt-cost-plus-risk-premium approach can be used when the business does not have publicly traded equity.

All approaches always produce estimates that fall within a narrow range.
