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.

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?
