Risks

BRK-B
  • ⚠FCF yield of 6.0% suggests reasonable valuation assuming continued moderate growth.
  • ⚠Trailing P/E of 15.2x is 72% above the historical average of 8.9x — the stock trades at a premium to its own history.
PNW
  • ⚠PEG ratio of 3.07 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.
  • ⚠High leverage (2.02x debt/equity) combined with thin interest coverage (-1.0x) poses financial risk.
