The Cost of Equity reflects the return a company needs to deliver to shareholders to justify the risk of investing in its shares. It’s computed using the Capital Asset Pricing Model (CAPM), which blends the risk-free rate, the stock’s beta, and the market risk premium.
This method evaluates the stock’s risk compared to a safe investment and the market’s overall volatility.
Here’s how we figure out the cost of equity for ESSO.BK:
cost_of_equity (16.35%) = risk_free_rate (2.85%) + equity_risk_premium (8.40%) * adjusted_beta (1.36) + risk_adjustments (0.25%)
We include the risk adjustments, which range from 0% to 1%, to keep our WACC conservatives, especially for companies traded in developing markets.
