Rewards

BRK-B
  • ★Each dollar of retained earnings has created $3.95 of earning power — management is an exceptional capital allocator.
  • ★PEG ratio of 0.13 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
  • ★Net debt/EBITDA of -2.3x means the company holds more cash than debt — a net cash position.
SPG
  • ★Gross margin of 81.9% indicates strong pricing power — typical of businesses with significant intellectual property or brand strength.
  • ★Return on equity has consistently exceeded 20% over 4 years, indicating efficient use of shareholder capital.
  • ★Each dollar of retained earnings has created $134.48 of earning power — management is an exceptional capital allocator.

Risks

BRK-B
  • ⚠FCF yield of 6.0% suggests reasonable valuation assuming continued moderate growth.
  • ⚠Trailing P/E of 15.2x is 72% above the historical average of 8.9x — the stock trades at a premium to its own history.
SPG
  • ⚠High leverage (4.35x debt/equity) combined with thin interest coverage (-1.0x) poses financial risk.
  • ⚠Net debt/EBITDA of 6.0x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
  • ⚠Altman Z-Score of 1.27 places the company in the distress zone — financial patterns resemble those of companies that experienced bankruptcy.
