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.

001How would you analyse a stock?JefferiesEquity Research · New York · 2026
Say this
Business first, then numbers, then price. Understand how the company makes money and whether that is durable, build a model of what it earns, then decide whether the current price already reflects it.
Then walk it
- Start with the business: what it sells, to whom, what share of revenue comes from where, and who it competes with. You cannot forecast what you cannot describe.
- Then the economics: unit economics, gross margin, operating leverage, return on invested capital, and where the cash actually goes.
- Then the durability question: what stops a competitor doing this? Switching costs, scale, network effects, regulation, brand. That determines whether today's margin survives.
- Then the model: forecast revenue by driver rather than by growth rate, build margin off the cost structure, and get to earnings and free cash flow.
- Then valuation and, critically, expectations. The key move in research is not 'what is it worth' but 'what is priced in'. I would reverse-engineer the current price into implied growth and margin, then ask whether I believe those numbers.
- The output is a rating, a target, and a variant view. Without a variant view there is no reason for anyone to read the note.
Where candidates lose it
Describing a valuation process rather than a research process. Anyone can build a DCF. The job is forming a differentiated view against consensus, so the expectations step has to appear in your answer.

- What is your variant view on that name?
- How do you know what is priced in?

002What moves a stock?Balyasny Asset ManagementEquity Hedge · Chicago · 2021
Say this
Changes in expectations, not the level of results. A stock moves when the market revises its forecast of future earnings, or revises the multiple it will pay for them. Everything else is noise around those two.
Then walk it
- Price equals earnings times multiple. So there are exactly two levers, and every catalyst works through one of them.
- Earnings revisions are the bigger driver over any meaningful horizon. That is why the sell-side obsesses over guidance and why a beat with a cut to guidance sells off.
- Multiple changes come from the rate environment, from perceived risk, and from a change in the durability of growth. A company that convinces the market its growth is recurring rather than cyclical gets re-rated without changing a single forecast.
- In the short run, positioning and flows matter enormously. A crowded long with everyone already in it can fall on good news because there is nobody left to buy.
- So the practical question for a research analyst is never 'are results good' but 'are results better than what is discounted'. That is why the expectations framework is the job.
Where candidates lose it
Answering 'earnings' and stopping. That misses the multiple entirely, and it misses the central insight that it is the delta versus expectations that matters, not the absolute result.
Expect next
- How do you think about valuation drivers?
- Why would a stock fall on a beat?
- How do you measure what is priced in?

043Why can a stock fall on an earnings beat?Long-short funds
Say this
Because the reported number is not what was priced. The market trades on the buy-side whisper and on forward guidance, so a company can beat published consensus and still disappoint on both.
Then walk it
- Published consensus lags. The real bar is the buy-side expectation, which is usually higher into a strong quarter and is not in any database.
- Guidance matters more than the quarter. A beat paired with unchanged full-year guidance implies a cut to the rest of the year, and the market does that arithmetic immediately.
- Quality of the beat: driven by a lower tax rate, a one-off gain, or a buyback reducing share count is very different from a beat on volume and price. The market discounts low-quality beats.
- Forward indicators can contradict the headline: billings, backlog, bookings, orders. A revenue beat with deteriorating bookings is a sell.
- Positioning: if everyone already owns it into the print, there is no marginal buyer. A crowded long needs a large beat just to hold its level.
- So the framework for a research analyst is always the expectations gap, and the most useful pre-results work is establishing where the buy-side bar actually sits, not what the screen says consensus is.
Where candidates lose it
Treating published consensus as the bar. The gap between published consensus and the buy-side whisper is exactly what this question is about, and naming it is the mark of someone who has watched results days.
Expect next
- How do you find out where the buy-side bar is?
- What is a low quality beat?
- How do you position into a print?
093What is a catalyst, and why do investors care so much about it?Hedge fundsLong-short funds
Say this
A specific identifiable event that causes the market to recognise the value you see. It matters because being right about value without a mechanism for the gap to close means you are just paying opportunity cost.
Then walk it
- Types: results that break a trend, guidance revision, a capital markets day, an asset sale or spin-off, a refinancing, a regulatory decision, a patent or contract event, index inclusion, or activist involvement.
- Why it matters for returns: IRR is time-sensitive. Making 30 percent in one year is very different from making 30 percent over five, and without a catalyst you cannot estimate the timeline.
- For a short it is more than useful, it is essential, because of borrow costs and unlimited downside. A short without a catalyst is a position that bleeds while you wait.
- In a fund with quarterly capital scrutiny, the catalyst is also what allows you to hold through drawdown, because you can point to the event that resolves the debate.
- The counterargument, worth giving: long-horizon compounders often have no catalyst at all, and demanding one biases you toward event-driven situations and away from quality businesses that simply keep compounding. Buffett-style investing is explicitly catalyst-free.
- So my position: for shorts and for value situations, insist on a catalyst. For quality compounders, the catalyst is the passage of time and continued execution, and that is legitimate as long as you say so explicitly.
Where candidates lose it
Insisting every position needs a catalyst without acknowledging that long-duration compounding does not. Knowing when the rule applies and when it does not is the more sophisticated answer.
Expect next
- What is the catalyst on your best idea?
- How long would you hold without one?
- Does a compounder need a catalyst?
