CHENNPETRO.NS's CAPM model and how its cost of Equity is calculated

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 CHENNPETRO.NS:

cost_of_equity (16.50%) = risk_free_rate (7.15%) + equity_risk_premium (8.80%) * adjusted_beta (0.88) + 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.
