Risks
MA
- ⚠High leverage (2.82x debt/equity) combined with thin interest coverage (-1.0x) poses financial risk.
- ⚠Insiders have sold $4.5M worth of stock in the past 3 months — significant insider liquidation.
MPWR
- ⚠Buybacks have been poorly timed — 2 out of 3 years involved repurchases at relatively expensive valuations.
