WACC is the discount rate used in all DCF models on this platform. It blends the cost of equity (CAPM) and after-tax cost of debt, weighted by market-cap-based capital structure.
Beta is derived using the bottom-up (sector) approach: peer betas are unlevered, the sector median is taken, then re-levered with the target company's own D/E ratio. This produces more stable betas than individual stock regression. Bloomberg adjustment (0.67 × β + 0.33 × 1.0) accounts for mean reversion.
