Rewards

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.
UNH
  • 5 insider purchases over the past 12 months with a buy/sell ratio above 3:1 — a sustained pattern of insider confidence.
  • Dividend yield of 3.15% with a consistent or growing payout over the past 4 years.

Risks

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.
UNH
  • ROIC has declined by 7.9 percentage points over the observed period, which may signal competitive erosion.
  • Gross margin of 18.5% is low, suggesting a competitive or commodity-like market with limited pricing power.
  • FCF yield of 5.4% suggests reasonable valuation assuming continued moderate growth.

Beneish's 8-variable model estimates the probability of earnings manipulation. 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.
