A critical weakness in many DCF models lies in the terminal value — an estimate of a company's worth far beyond the initial forecast period. Often accounting for up to 80% of the total valuation, terminal value typically rests on two big assumptions: The company will survive and thrive for decades.

What are the weaknesses of DCF?

The main Cons of a DCF model are:

Very sensitive to changes in assumptions. A high level of detail may result in overconfidence. Looks at company valuation in isolation. Doesn't look at relative valuations of competitors.

When would a DCF not work?

What types of companies can't be valued using the standard DCF model?

  • Insurance companies (driven by written premiums and claims)
  • Private equities/other balance-sheet-based financial companies (driven by proprietary investments)
  • REITs (driven by property assets)

Why discounted cash flow is better than non discounted cash flow?

What is a disadvantage of the free cash flow valuation method?

Public Perception: There is occasional criticism from the public and media regarding the decisions not to prosecute certain cases, which can affect the CPS's reputation.

When would you not use a DCF?

We do not use a DCF if the company has unstable or unpredictable cash flows (tech or bio-tech start-up) or when debt and working capital serve a fundamentally different role.

Is it better to use levered or unlevered DCF?

A levered DCF therefore attempts to value the Equity portion of a company's capital structure directly, while an unlevered DCF analysis attempts to value the company as a whole; at the end of the unlevered DCF analysis, Net Debt and other claims can be subtracted out to arrive at the residual (Equity) value of the ...

How accurate is DCF valuation?

While the discounted cash flow (DCF) methodology is the most rigorous and financially sound for business valuation, it does have several significant limitations, namely: Extreme sensitivity to certain input assumptions. Uncertainty in calculating the terminal value of the company.

Can you do a DCF on an unprofitable company?

Since price-to-earnings (P/E) ratios cannot be used to value unprofitable companies, alternative methods have to be used. These methods can be direct—such as discounted cash flow (DCF) or relative valuation.
