Methodology
The AInvestor model evaluates stocks using four complementary valuation methods:
1. Discounted Cash Flow (DCF)
Projects 5-year free cash flows discounted at WACC, with terminal value based on 3.5% growth assumption.
2. Peter Lynch Fair Value
Formula: EPS × Growth Rate (%) - represents the fair value based on earnings and expected growth.
3. Trading Multiples Valuation (TMV)
Calculates industry average P/E from peer companies using IQR outlier detection, then multiplies by company EPS.
4. Earnings Power Value (EPV)
Formula: (1 - Tax Rate) × EPS / WACC - conservative valuation assuming no growth.
Final fair value uses weighted average: 25% DCF, 25% Peter Lynch, 25% TMV, 25% EPV
Composite scoring incorporates:
- Financial Health (55 points): P/E, market cap, ROE, D/E, dividend, beta, FCF, growth, margins, liquidity
- Competitive Moat (25 points): ROIC-WACC spread, gross margin, growth, IP, qualitative factors
- Macro Risk (10 points): Geopolitical and economic exposure
- Risk-Adjusted Returns (10 points): Sharpe ratio analysis
