Explain the concept of cost of equity and how it is calculated.

The cost of equity refers to the return that a company's shareholders require in order to invest in the company's stock. It represents the opportunity cost of investing in the company's equity rather than in alternative investments with similar risk profiles. The cost of equity is calculated using the Capital Asset Pricing Model (CAPM) or other similar models. The formula for calculating the cost of equity using CAPM is as follows:

Cost of Equity = Risk-Free Rate + Beta * (Market Return - Risk-Free Rate)

In this formula, the risk-free rate represents the return on a risk-free investment such as a government bond, the beta measures the stock's sensitivity to market movements, and the market return represents the expected return on the overall market. By plugging in the appropriate values for these variables, the cost of equity can be determined.
