Cost of new equity should be the adjusted cost for any underwriting fees termed flotation costs (F): K e = D 1 /P 0 (1-F) + g; where F = flotation costs, D 1 is dividends, P 0 is price of the stock, and g is the growth rate. There are 3 ways of calculating K e: Capital Asset Pricing Model; Dividend Discount Method; Bond Yield Plus Risk Premium ...
A 2022 study of the stock market in Norway found that the magic formula generates risk-adjusted excess returns. Over the sample period (2003-2022) the strategy had a CAGR of 21.56%. However, these returns may not be achievable in real-world conditions due to the impact of transaction costs.
