Rewards

AAPL
  • Apple Inc. has maintained ROIC above 15% for 4 consecutive years, indicating a durable competitive advantage.
  • Apple Inc. scores 96/100 on the Economic Moat Score (Wide Moat), with roic consistency as the strongest competitive dimension.
  • Return on equity has consistently exceeded 20% over 4 years, indicating efficient use of shareholder capital.
STLD
  • Share count has been reduced by 16% over the past 4 years through buybacks, increasing each share's claim on earnings.
  • PEG ratio of 0.26 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
  • Altman Z-Score of 5.05 indicates very low bankruptcy risk — the company is firmly in the safe zone.

Risks

AAPL
  • FCF yield of 2.5% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
  • Insiders have sold $24.6M worth of stock in the past 3 months — significant insider liquidation.
STLD
  • ROIC has declined by 29.5 percentage points over the observed period, which may signal competitive erosion.
  • Gross margin of 14.0% is low, suggesting a competitive or commodity-like market with limited pricing power.
  • Buybacks have been poorly timed — 3 out of 4 years involved repurchases at relatively expensive valuations.
