Rewards

MS
  • Gross margin of 87.6% indicates strong pricing power — typical of businesses with significant intellectual property or brand strength.
  • Morgan Stanley scores 80/100 on the Economic Moat Score (Wide Moat), with revenue predictability as the strongest competitive dimension.
  • Each dollar of retained earnings has created $3.56 of earning power — management is an exceptional capital allocator.
WDC
  • Each dollar of retained earnings has created $12.03 of earning power — management is an exceptional capital allocator.
  • PEG ratio of 0.81 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
  • Altman Z-Score of 21.83 indicates very low bankruptcy risk — the company is firmly in the safe zone.

Risks

MS
  • Altman Z-Score of 0.29 places the company in the distress zone — financial patterns resemble those of companies that experienced bankruptcy.
  • Insiders have sold $5.4M worth of stock in the past 3 months — significant insider liquidation.
WDC
  • Share count has increased by 12% over the past 4 years, diluting existing shareholders.
  • Despite buyback spending, shares outstanding increased in 3 out of 3 years — stock-based compensation is offsetting repurchases.
  • FCF yield of 2.3% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
