Fundamental Analysis

> **This skill has been merged into `stock-eval`.** Use `/us-stock-analysis:stock-eval` for comprehensive fundamental + quality + valuation analysis.

Quick Reference — Key Ratios

| Ratio | Formula | What It Measures | |-------|---------|-----------------| | **P/E** (Price-to-Earnings) | Market Price / EPS | How much investors pay per dollar of earnings; compare to peers and history | | **P/B** (Price-to-Book) | Market Price / Book Value per Share | Premium over net asset value; useful for financials and asset-heavy businesses | | **P/S** (Price-to-Sales) | Market Cap / Revenue | Valuation relative to revenue; useful when earnings are negative or depressed | | **EV/EBITDA** | Enterprise Value / EBITDA | Capital-structure-neutral earnings multiple; standard M&A and cross-sector benchmark | | **ROE** (Return on Equity) | Net Income / Shareholders' Equity | Profitability relative to equity book value; decompose with DuPont for quality assessment | | **ROIC** (Return on Invested Capital) | NOPAT / Invested Capital | True economic return on all capital deployed; compare to WACC to assess value creation | | **Current Ratio** | Current Assets / Current Liabilities | Short-term liquidity; >1.5x generally healthy; <1.0x signals potential liquidity stress | | **D/E** (Debt-to-Equity) | Total Debt / Shareholders' Equity | Financial leverage; higher ratio = more risk but also more return amplification |

Standard Signal Output

All analysis concludes with this standardized block:

## Thesis Invalidation

After delivering the analysis signal, specify what would reverse it:

**If signal is BULLISH — thesis breaks if:**
- revenue growth decelerates below 5% for 2 consecutive quarters AND gross margin contracts >200bps
- [One or two more triggers drawn from this analysis's own drivers, each with a threshold]

**If signal is BEARISH — thesis breaks if:**
- revenue reaccelerates >15% AND margin expansion resumes
- [One or two more triggers drawn from this analysis's own drivers, each with a threshold]

**Re-run this analysis when:**
- [ ] Next earnings release
- [ ] Price moves ±15% from current level
- [ ] 60 days have elapsed
- [ ] Material news event (acquisition, leadership change, regulatory decision)
