Question

What are the most common junior pitfalls in DCF models that senior analysts/associates spot immediately?

Answer

Top 10 junior pitfalls:

  • Cash-flow sign errors: capex entered as positive instead of negative in the FCF bridge.
  • Stub-period discounting wrong: the first period isn't adjusted for the stub months.
  • Mid-year convention forgotten: cash flows should often be discounted with a half-year, not end-of-period.
  • Terminal-year cash-flow inconsistency: the TV cash flow must be 'steady state' — no investment spike, normalized capex, normalized working-capital changes.
  • Implied terminal multiple sanity check missing: the TV often implies 30x EBITDA — implausible.
  • WACC beta levering inconsistent: beta not relevered to the target capital structure.
  • Tax-shield double-counting in UFCF + WACC.
  • Net-debt cut-off date: taken at the last balance-sheet date rather than the valuation date.
  • Forward-EBITDA ring-fencing: using an NTM multiple but LTM EBITDA, or vice versa.
  • Sensitivity table not symmetric.
