Rewards

  • Each dollar of retained earnings has created $3.80 of earning power — management is an exceptional capital allocator.

Risks

ORCL

  • High leverage (3.15x net debt/equity) combined with thin interest coverage (-1.0x) poses financial risk.
  • Net debt/EBITDA of 4.4x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
TDG
  • 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.
