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 601666.SS:
cost_of_equity (14.35%) = risk_free_rate (2.95%) + equity_risk_premium (6.60%) * adjusted_beta (1.62) + risk_adjustments (0.25%)
