Risks
GLW
- ⚠Despite buyback spending, shares outstanding increased in 3 out of 4 years — stock-based compensation is offsetting repurchases.
- ⚠FCF yield of 1.0% is below 3%, meaning the market is pricing in substantial future growth to justify the current price.
- ⚠Trailing P/E of 76.5x is 59% above the historical average of 48.0x — the stock trades at a premium to its own history.
TSLA
- ⚠ROIC has declined by 17.7 percentage points over the observed period, which may signal competitive erosion.
- ⚠Gross margin of 19.1% is low, suggesting a competitive or commodity-like market with limited pricing power.
- ⚠Share count has increased by 19% over the past 4 years, diluting existing shareholders.
