Rewards

AMZN
  • Each dollar of retained earnings has created $5.34 of earning power — management is an exceptional capital allocator.
  • Trailing P/E of 32.4x is 20% 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.
SPGI
  • Gross margin of 70.5% indicates strong pricing power — typical of businesses with significant intellectual property or brand strength.
  • S&P Global Inc. scores 71/100 on the Economic Moat Score (Wide Moat), with revenue predictability as the strongest competitive dimension.
  • Free cash flow has grown at a 29.5% CAGR over the past 4 years, demonstrating strong earnings power growth.

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.
