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 NTGY.MC:
cost_of_equity (9.30%) = risk_free_rate (3.35%) + equity_risk_premium (7.90%) * adjusted_beta (0.62) + risk_adjustments (0.25%)
