  • Dividend yield of 6.53% with a consistent or growing payout over the past 4 years.

  • Each dollar of retained earnings has created $5.83 of earning power — management is an exceptional capital allocator.
  • PEG ratio of 0.69 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.

Risks

PFE
  • ROIC has declined by 13.9 percentage points over the observed period, which may signal competitive erosion.
  • PEG ratio of 13.77 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.

  • Trailing P/E of 35.3x is 56% above the historical average of 22.7x — the stock trades at a premium to its own history.
  • Net debt/EBITDA of 4.4x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
  • Altman Z-Score of 1.11 places the company in the distress zone — financial patterns resemble those of companies that experienced bankruptcy.
