Risks
AMT
- ⚠FCF yield of 5.5% suggests reasonable valuation assuming continued moderate growth.
- ⚠High leverage (4.45x debt/equity) combined with thin interest coverage (-1.0x) poses financial risk.
- ⚠Net debt/EBITDA of 6.2x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
AVGO
- ⚠Share count has increased by 13% over the past 4 years, diluting existing shareholders.
- ⚠FCF yield of 1.3% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
- ⚠PEG ratio of 2.59 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.
