A discount rate is the rate of return that an investor requires on an investment to compensate them for the risk they are taking. The WACC is the opportunity cost of a company's capital, which is the rate of return that a company could obtain from other investments if it were to invest its capital elsewhere.
To estimate the WACC, investors use a capital asset pricing model (CAPM), which is a formula that relates the expected return on an investment to the risk-free rate. The formula is:
WACC = Rf + β * (Rm - Rf)
where:
Rf is the risk-free rate
R^m is the expected return on the stock market
β is the beta of the stock
R^f is the expected return on a risk-free asset
The beta of a stock measures its volatility compared to the overall stock market. A stock with a high beta is more volatile than the overall stock market, and thus has a higher beta. The expected return on a stock with a high beta is therefore higher than the expected return on a stock with a low beta.
Once the WACC has been estimated, investors can use it to compare the intrinsic value of a stock to its market price. If the intrinsic value of the stock is higher than its market price, the stock is overvalued. Conversely, if the intrinsic value of the stock is lower than its market price, the stock is undervalued.
Estimating the WACC is an important step in financial modeling and valuation. By understanding the WACC, investors can make more informed investment decisions and improve the accuracy of their financial models and valuations
