## Agent interpretation

14 S\&P 500 stocks pass the screen. A few observations:

1. **VTRS** (Viatris) is the standout at 7.2x PE with 18.3% ROE:extremely cheap on paper.
2. **ABBV** has exceptional ROE (47.2%) but the high leverage (5.73x debt/equity) is inflating it. High ROE from a small equity base, not operational efficiency.
3. **MOS** looks most interesting: low PE (8.1x), strong ROE (22.1%), conservative leverage (0.41x), and double-digit revenue growth (11%):the full package.
