Rewards

META
  • Meta Platforms, Inc. has maintained ROIC above 15% for 4 consecutive years, indicating a durable competitive advantage.
  • Gross margin of 81.7% indicates strong pricing power — typical of businesses with significant intellectual property or brand strength.
  • Meta Platforms, Inc. scores 80/100 on the Economic Moat Score (Wide Moat), with roic consistency as the strongest competitive dimension.
STX
  • Trailing P/E of 61.7x is 98% below the historical average of 2797.0x — potentially undervalued relative to its own history.
  • PEG ratio of 0.49 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
  • Altman Z-Score of 4.80 indicates very low bankruptcy risk — the company is firmly in the safe zone.

Risks

META
  • Buybacks have been poorly timed — 3 out of 4 years involved repurchases at relatively expensive valuations.
  • Insiders have sold $6.7M worth of stock in the past 3 months — significant insider liquidation.
STX
  • FCF yield of 1.0% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.

  • 20 insider sales totaling $120.8M with no purchases in the past 3 months — insiders are reducing their exposure.
