Rewards

TER
  • Teradyne, Inc. has maintained ROIC above 15% for 4 consecutive years, indicating a durable competitive advantage.
  • PEG ratio of 0.20 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
  • Altman Z-Score of 14.86 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

TER
  • FCF yield of 0.8% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
  • Trailing P/E of 63.0x is 69% above the historical average of 37.3x — the stock trades at a premium to its own history.
  • 6 insider sales 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.
