Rewards

BAC
  • Each dollar of retained earnings has created $2.37 of market value — management is an exceptional capital allocator.
  • PEG ratio of 0.58 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
MMM
  • Altman Z-Score of 4.26 indicates very low bankruptcy risk — the company is firmly in the safe zone.

Risks

BAC
  • Gross margin of 0.0% is low, suggesting a competitive or commodity-like market with limited pricing power.
  • Bank of America Corporation scores only 20/100 on the Economic Moat Score, suggesting limited durable competitive advantages.
  • Altman Z-Score of 0.22 places the company in the distress zone — financial patterns resemble those of companies that experienced bankruptcy.
MMM
  • FCF yield of 1.7% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
  • Trailing P/E of 23.8x is 34% above the historical average of 17.8x — the stock trades at a premium to its own history.
  • High leverage (2.77x debt/equity) combined with thin interest coverage (-1.0x) poses financial risk.
