Rewards

ADI
  • Gross margin of 62.8% indicates strong pricing power — typical of businesses with significant intellectual property or brand strength.
  • PEG ratio of 0.62 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
  • Altman Z-Score of 6.46 indicates very low bankruptcy risk — the company is firmly in the safe zone.
UNH
  • Dividend yield of 2.40% with a consistent or growing payout over the past 4 years.

Risks

ADI
  • FCF yield of 2.1% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
  • Trailing P/E of 72.4x is 57% above the historical average of 46.1x — the stock trades at a premium to its own history.
  • 5 insider sales totaling $12.2M with no purchases in the past 3 months — insiders are reducing their exposure.
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.
