Rewards

AMZN
  • Each dollar of retained earnings has created $5.34 of earning power — management is an exceptional capital allocator.
  • Trailing P/E of 32.1x is 21% below the historical average of 40.6x — potentially undervalued relative to its own history.
  • PEG ratio of 0.43 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
TMO
  • Dividend yield of 0.38% with a consistent or growing payout over the past 4 years.
  • Trailing P/E of 25.8x is 20% below the historical average of 32.3x — potentially undervalued relative to its own history.
  • Altman Z-Score of 3.85 indicates very low bankruptcy risk — the company is firmly in the safe zone.

Risks

AMZN
  • FCF yield of 0.3% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
  • 13 insider sales totaling $29.0M with no purchases in the past 3 months — insiders are reducing their exposure.
TMO
  • PEG ratio of 2.28 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.
  • 5 insider sales totaling $8.3M with no purchases in the past 3 months — insiders are reducing their exposure.
