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 $35.82 of market value — management is an exceptional capital allocator.
- ★Trailing P/E of 78.6x is 43% below the historical average of 138.5x — potentially undervalued relative to its own history.
DGX
- ★Each dollar of retained earnings has created $1.03 of market value — management is creating shareholder value.
Risks
AMD
- ⚠Despite buyback spending, shares outstanding increased in 3 out of 4 years — stock-based compensation is offsetting repurchases.
- ⚠FCF yield of 2.0% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
- ⚠8 insider sales totaling $54.7M with no purchases in the past 3 months — insiders are reducing their exposure.
DGX
- ⚠FCF yield of 6.3% suggests reasonable valuation assuming continued moderate growth.
- ⚠PEG ratio of 2.01 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.
- ⚠Insiders have sold $10.7M worth of stock in the past 3 months — significant insider liquidation.
