BAC
Bank of America Corporation
$47.01
VS
DGX
Quest Diagnostics Incorporated
$194.16

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.
DGX
  • Each dollar of retained earnings has created $1.03 of market value — management is creating shareholder value.

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.
DGX
  • FCF yield of 6.3% suggests reasonable valuation assuming continued moderate growth.
  • PEG ratio of 2.01 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.
  • Insiders have sold $10.7M worth of stock in the past 3 months — significant insider liquidation.

An M-Score above -1.78 signals elevated risk — companies in this range have historically been 3-5× more likely to be manipulating earnings. Scores between -2.22 and -1.78 fall in a grey zone warranting further investigation.
