How Top Funds Prepare for Earnings Season
Top funds prepare for earnings by refreshing driver forecasts, writing down what they expect and what would surprise them, listing the exact questions each print must answer, and pre-committing to how they will react.
Top funds prepare for earnings by doing the thinking before the number lands, not after. For each holding they refresh the driver forecast, write down what they expect and what would genuinely surprise them, list the exact questions the print must answer, and pre-commit to how they will react to a beat, a miss, or an in-line result. When the result actually arrives, it becomes a checklist to run against a prior belief, rather than a scramble to work out what it means in real time.
This is the quiet difference between a desk that treats earnings season as an event and one that treats it as a scheduled test of work already done. The result is public and unavoidable, so the only variable you control is how much of your opinion is formed before it. That preparation is what we examine here. Reading the call itself, live, is a separate craft we cover in how to read a concall like an analyst; here the focus is everything you do in the days before management opens its mouth.
Why the work has to happen before the print
A number read cold has no reference point. If you see a revenue figure with no prior expectation attached, you cannot tell whether it is good, bad, or exactly what the business was always going to do. So you borrow a reference point from the nearest available source, which is usually the market’s first reaction and the headline framing. That is the moment your independent judgement quietly disappears.
A written expectation fixes this. If you decided beforehand that a segment should grow in a certain range, and it lands outside that range, you now have a real signal: either the business changed or your model was wrong, and both are worth knowing. The print stops being news and becomes a comparison. This is also the only honest way to find out whether your forecasting is any good, because the score is only meaningful if you wrote the answer down before the reveal.
A number you did not have an expectation for cannot surprise you. It can only be explained to you by whoever reacts first.
Step one: refresh the driver forecast
Preparation starts by rebuilding the forecast for the handful of things that actually decide the quarter. Not the full model line by line, but the two or three operating drivers the outcome rests on: volumes and realisation for a consumer goods maker, subscribers and average revenue per user for a telecom operator, order inflow for a capital goods company, loan growth and margin for a lender.
The point is to arrive at the print with an explicit view, expressed as a range rather than a single point. A range is honest about uncertainty and it makes the later comparison sharper, because you know in advance which outcomes sit inside your thesis and which fall outside it. How to build that forecast from drivers and leading indicators is its own discipline, covered in how analysts forecast revenue before earnings. For preparation, the deliverable is simple: a written expected range for each key driver, and the assumption underneath it that you are really betting on.
Step two: write down what you expect and what would surprise you
Once you have driver ranges, translate them into a short expectation sheet. Two columns are enough. The first is what you expect: the base case for each driver and for the one or two summary numbers, revenue and margin, that the market will anchor on. The second is what would surprise you: the specific outcomes that would sit clearly outside your range in either direction.
The surprise column is the valuable half, and most people skip it. Naming your surprises in advance forces you to separate a genuine thesis break from ordinary noise before your emotions get a vote. A margin two hundred basis points below your range is a surprise worth investigating. A margin twenty basis points below it is not, and writing that down beforehand stops you from over-reacting to a rounding error dressed up as a story.
Step three: turn last quarter’s guidance into a test
Every prior earnings call left behind forward claims. Preparation means pulling those claims back out and turning them into a pass or fail test for the print in front of you. Guidance is a number wrapped in a hedge, and the exact words matter, so use them exactly.
Take a public, neutral example. On its forward outlook, Asian Paints management guided to “high single-digit volume growth in the band of about 8-10%”, and pointed to an 18-20% EBITDA margin band while speaking of “maintaining our margin guidance”. If you hold or follow that kind of name, those two statements become concrete tests you carry into the next print. Is reported volume growth tracking inside 8 to 10 percent, or drifting below it? Is the margin landing inside 18 to 20 percent? And, just as important, does management still use the word “maintaining”, or has the language softened to something more cautious? A band walked back in words often arrives before it shows up in the numbers.
This is why guidance is only useful if you record it and grade it, a habit we go deeper on in what management guidance really means. Preparation is where the grading gets set up: you decide, before the print, exactly which promises this quarter is being marked against.
Step four: list the exact questions this print must answer
Now write the questions. Not vague ones like “how is the business doing”, but specific, answerable ones tied to your thesis. If your thesis rests on a new product ramping, the question is whether that product’s contribution moved this quarter. If it rests on margins recovering as input costs ease, the question is whether gross margin expanded and whether management attributes it to the reason you assumed.
A good pre-earnings question list has a useful property: each item has a clear place the answer will appear, in the results, the segment tables, or the call. That is what turns the live event into a checklist. When the print drops, you are not reading everything at once trying to form a view. You are running down a short list of questions you already knew you needed answered, which is the whole point of preparing.
Step five: pre-commit to how you will react
The last step is the one that separates process from good intentions. For each holding, decide in advance what a beat, a miss, and an in-line result would mean, and what you would do about each. Not a trading rule, but a thesis rule: which outcomes confirm the thesis, which ones dent it enough to demand a re-underwrite, and which ones would genuinely break it.
Pre-committing matters because the moments right after a print are the worst possible time to form a considered view. The price is moving, the framing is loud, and the temptation is to rationalise whatever just happened into agreement with your existing position. A reaction written down while you were calm is your defence against that. It also connects earnings to the rest of your work: a thesis is a living document that each print updates, a discipline we cover in treating your thesis as a living document, and pre-committed reactions are how a quarter actually feeds back into it.
The pre-earnings checklist, in one view
| Step | Do this before the print | What it produces |
|---|---|---|
| Refresh drivers | Rebuild the two or three drivers that decide the quarter | An expected range per driver |
| Write expectations | Fill an expect column and a surprise column | A line between noise and signal |
| Test guidance | Pull prior guidance words back out | A pass or fail test for the print |
| List questions | Write specific, answerable questions | A checklist to run live |
| Pre-commit reactions | Decide beat, miss, and in-line responses | A calm decision made in advance |
None of this is exotic. It is the same forecast, guidance, and thesis work a desk does all year, pulled forward and pointed at a known date. What makes it feel different at scale is doing it across many names at once, on a compressed calendar, without letting the last few holdings get a rushed version of the first few. That consistency, quarter after quarter, is a large part of what continuous research actually buys you, and it is why AI matters here: the tireless first pass of refreshing numbers and pulling last quarter’s exact words back out is precisely the grunt work that should be automated, so the human hours go to judgement, the surprise column, and the pre-committed reaction.
Earnings season rewards the desk that already knew what it was looking for. The print is the same for everyone; the preparation is not. If the work is done in the quiet days before, a result is just an answer to a question you had already written down, which is a far better place to be than reading a number cold and hoping the market tells you what to think.
Frequently asked questions
How do top funds prepare for earnings season?
They do the thinking before the number lands. For each holding they refresh the driver forecast, write down what they expect and what would surprise them, list the exact questions the print must answer, and decide in advance how they will react to each plausible outcome. When the result arrives, it becomes a checklist to run, not a scramble to interpret.
What should you write down before a company reports?
Your expected numbers for the two or three drivers that matter, the specific words in management's last guidance that this quarter should confirm or break, the questions you need the call to answer, and your pre-committed reaction to a beat, a miss, and an in-line result. Writing it down before the print is what stops the number from writing your opinion for you.
Why prepare before earnings instead of just reading the result?
Because a number read cold has no reference point, so you end up borrowing the market's reaction instead of testing your own thesis. A written expectation turns the print into a comparison against what you already believed, which is the only way to learn whether your model was right and whether your thesis still holds.
What is the difference between preparing for earnings and reading the earnings call?
Preparation is the work you do in the days before the print: refreshing forecasts, writing expectations, and listing questions. Reading the call is the live work of hearing management answer. Good preparation is what makes the call useful, because you already know exactly what you are listening for.
