Rewards

GM

  • FCF yield of 32.9% is historically attractive — the business generates significant cash relative to its price.

UNH
  • ROIC has declined by 7.9 percentage points over the observed period, which may signal competitive erosion.
  • Gross margin of 18.8% is low, suggesting a competitive or commodity-like market with limited pricing power.
  • FCF yield of 5.3% suggests reasonable valuation assuming continued moderate growth.
