Equity Research interview preparation
Sell side and buy side. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it. Answers lead with the point, then the mechanism, then the limitation.

016Walk me through a DCF, and tell me when it is the wrong tool for a research analyst.JefferiesEquity Research · New York · 2026MorningstarEquity Research · Chicago · 2023
Say this
Forecast unlevered free cash flow, discount at WACC, add a terminal value, then bridge to equity value per share. It is the wrong tool when the terminal value dominates so completely that the answer is just your assumption restated.
Then walk it
- The mechanics are the same as on the banking side: EBIT taxed, plus D&A, less CapEx, less working capital change, discounted at WACC, plus terminal value, less net debt, divided by diluted shares.
- Where research differs is the use. A sell-side target price is usually set on a multiple, with the DCF as a cross-check and a way to demonstrate what the market is implying.
- The most valuable version is the reverse DCF: hold the current price constant and solve for the growth and margin the market must be assuming. That turns valuation into a testable statement about expectations.
- It is the wrong tool for banks and insurers, where you use a dividend discount or residual income model because interest is revenue and free cash flow is not meaningful.
- It is also weak for early-stage or deeply cyclical companies, where near-term cash flows are negative or unrepresentative and 90 percent of the value sits in the terminal assumption.
- So the honest framing: a DCF is most useful not for the number it produces but for making explicit what you have to believe.
Where candidates lose it
Delivering the banking answer verbatim. On the research side the expected addition is the reverse DCF and the awareness that DCFs are rarely the primary target-setting method. Say both.
Expect next
- How would you value a bank then?
- What does the reverse DCF tell you about this stock?
- What discount rate do you use and why?

Firm tags come from public, anonymous candidate reports on Wall Street Oasis: strong signal, not sworn testimony. Firms are named as the places a question was reported, not as partners of Fin Maverick. Answers are written for this page to show how to think out loud; they are not scripts to recite.
