Rewards

FSLR
  • Each dollar of retained earnings has created $4.79 of earning power — management is an exceptional capital allocator.
  • Trailing P/E of 13.7x is 26% below the historical average of 18.4x — potentially undervalued relative to its own history.
  • PEG ratio of 0.21 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
PFE
  • Gross margin of 75.8% indicates strong pricing power — typical of businesses with significant intellectual property or brand strength.
  • Dividend yield of 6.53% with a consistent or growing payout over the past 4 years.
  • FCF yield of 9.0% is historically attractive — the business generates significant cash relative to its price.

Risks

FSLR
  • FCF yield of 5.0% suggests reasonable valuation assuming continued moderate growth.
  • 39 insider sales totaling $15.0M with no purchases in the past 3 months — insiders are reducing their exposure.
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.
  • Free cash flow has declined at a 29.6% CAGR over the past 4 years — a concerning trend.
