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.
BLDR
  • Share count has been reduced by 20% over the past 4 years through buybacks, increasing each share's claim on earnings.
  • FCF yield of 9.1% is historically attractive — the business generates significant cash relative to its price.
  • Market sentiment is in extreme fear territory (score: 23/100) — historically, periods of fear have often presented buying opportunities.

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.
BLDR
  • ROIC has declined by 28.7 percentage points over the observed period, which may signal competitive erosion.
  • Buybacks have been poorly timed — 3 out of 4 years involved repurchases at relatively expensive valuations.
  • Trailing P/E of 21.7x is 46% above the historical average of 14.9x — the stock trades at a premium to its own history.
