Rewards

AMD
  • Free cash flow has grown at a 29.3% CAGR over the past 4 years, demonstrating strong earnings power growth.
  • Each dollar of retained earnings has created $2.01 of earning power — management is an exceptional capital allocator.
  • Management has timed buybacks well — 3 out of 4 years showed value-accretive repurchases.
TDG
  • TransDigm Group Incorporated has maintained ROIC above 10% for 4 consecutive years, suggesting solid business economics.
  • TransDigm Group Incorporated scores 94/100 on the Economic Moat Score (Wide Moat), with margin stability as the strongest competitive dimension.
  • Free cash flow has grown at a 29.9% CAGR over the past 4 years, demonstrating strong earnings power growth.

Risks

AMD
  • Despite buyback spending, shares outstanding increased in 3 out of 4 years — stock-based compensation is offsetting repurchases.
  • FCF yield of 0.8% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
  • Trailing P/E of 179.7x is 30% above the historical average of 138.5x — the stock trades at a premium to its own history.
TDG
  • FCF yield of 2.1% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
  • PEG ratio of 3.05 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.
  • Net debt/EBITDA of 5.8x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
