Earnings Guidance: The Part That Moves

Earnings guidance is a company's own forecast for its coming quarter or year, given alongside its results. Because results describe a period that has ended and guidance describes one that has not, guidance is usually the part that moves the share price.

How it works

A candlestick chart of the site's shared price history. The headline on the chart reads: The company's own forecast of its next quarter.

Guidance is the company forecasting itself. Management states what it expects revenue, margin or profit to be over the coming quarter or year, usually as a range.

A gently rising stretch of the long price series. The headline on the chart reads: Results are the past; guidance is the part that moves price.
Results are the past; guidance is the part that moves price. Illustrative chart - not real market data.

Results describe a period that has ended. By the time they are published, most of what they contain has been inferred from other sources. Guidance is genuinely new information about a period nobody has data on.

A calmly advancing stretch of the long price series. The headline on the chart reads: A beat with weak guidance falls, and it looks wrong.
A beat with weak guidance falls, and it looks wrong. Illustrative chart - not real market data.

Which is why a beat can fall. Better-than-expected results with a reduced outlook is a common combination, and the share price follows the outlook — a sequence that reads as irrational until you notice the market was already positioned for the quarter that just ended.

Reading it properly

A choppy, directionless stretch of the long price series. The headline on the chart reads: Guidance is set low enough to be beaten, deliberately.
Guidance is set low enough to be beaten, deliberately. Illustrative chart - not real market data.

The bar is set to be cleared. Management has every incentive to guide conservatively and then beat, so a beat against the company’s own guidance is close to meaningless as evidence of performance.

A flat, quiet stretch of the long price series. The headline on the chart reads: It arrives as a range, and the midpoint is the number.
It arrives as a range, and the midpoint is the number. Illustrative chart - not real market data.

It usually arrives as a range. The midpoint is what gets compared, and a range whose midpoint is unchanged but whose bottom end has fallen is a company widening its own uncertainty.

A strongly rising stretch of the long price series. The headline on the chart reads: Compare it with the analyst consensus, not with last year.
Compare it with the analyst consensus, not with last year. Illustrative chart - not real market data.

The comparison that matters is against consensus. Guidance above last year and below what analysts expected is a downgrade in the only sense the market cares about, because expectations are already in the price.

A declining stretch of the long price series. The headline on the chart reads: Withdrawing it entirely is the strongest signal available.
Withdrawing it entirely is the strongest signal available. Illustrative chart - not real market data.

Withdrawing guidance is the loudest version. A company that declines to forecast is saying it does not know, and uncertainty from management is priced harder than a bad number. Suspension is usually a larger move than a cut, which is worth knowing before an announcement rather than after.

In practice

A candlestick chart with a volume histogram beneath it, with the volume histogram emphasised. The headline on the chart reads: Participation on the reaction is what makes it stick.
Participation on the reaction is what makes it stick. Illustrative chart - not real market data.

Watch participation on the reaction. A large move on heavy volume is a repricing; the same move on thin volume is frequently retraced within days.

A long-horizon candlestick view of the same price series. The headline on the chart reads: And the rerating takes days, not the first minute.
And the rerating takes days, not the first minute. Illustrative chart - not real market data.

The full adjustment takes days. Analyst models get updated, institutional positions get changed, and the first minute’s move is frequently not the final one in either direction.

A candlestick series containing several opening gaps, with the largest opening gap marked. The headline on the chart reads: The move happens at an open, with no chance to react.
The move happens at an open, with no chance to react. Illustrative chart - not real market data.

Guidance arrives outside market hours, so the move is a gap. There is no opportunity to act between the news and the price.

A declining stretch of the long price series, with the entry price and the level at which a stop would trigger drawn as horizontal lines. The headline on the chart reads: A stop gives no protection through the announcement.
A stop gives no protection through the announcement. Illustrative chart - not real market data.

A stop does not protect a position through an announcement. It fills at the open, wherever that is, which is why holding through earnings is a position-size decision rather than a stop decision.

A candlestick chart of the site's shared price history, annotated with the round-trip cost. The headline on the chart reads: And the spread widens above the usual share of a bar.
And the spread widens above the usual share of a bar. Illustrative chart - not real market data.

Costs rise around the event. The round trip is 2% of a median bar’s range in normal conditions on this site’s shared history, and spreads widen materially at an open following news.

A 72-bar candlestick section of the shared price history. The headline on the chart reads: The book empties out before the number lands.
The book empties out before the number lands. Illustrative chart - not real market data.

Resting liquidity is withdrawn ahead of the release. Market makers reduce their exposure before a known event, which is the mechanical reason the move is large and the fill is poor.

What to actually do with it

The honest position for most traders is to have no position through the announcement. A binary event with a gap-shaped outcome and no stop protection is a coin flip with a spread attached, and there is no skill component available to offset that.

If you do hold, size it as though the gap will happen. Work out what a 10% adverse open would cost and decide whether that is acceptable, rather than working out where the stop goes. The alternative — trading the reaction rather than the event — has the advantage that the information is already public, and the first minute’s move is frequently reversed, which is at least a testable proposition rather than a guess.

One phrase in a guidance statement is worth more attention than the numbers: the reason given for a change. A cut attributed to one customer, one region or one delayed contract is a different proposition from one attributed to demand. The first is an event; the second is a trend, and the market prices them very differently.

Management’s language is deliberate and the qualifiers are load-bearing. “Softness” is smaller than “weakness”, and both are smaller than a withdrawn forecast. Read the outlook paragraph as prose rather than scanning it for a number — the sentence explaining the change usually says more about the next two quarters than the range does.

What earnings guidance is not

It is not a result. It is a forecast the company makes about itself.

It is not neutral. The bar is set to be beaten.

It is not required. Many companies give none at all.

And it is not tradeable in advance. The move is a gap.

When it fails

A sideways, range-bound candlestick series. The headline on the chart reads: In a range the reaction fades inside two sessions.
In a range the reaction fades inside two sessions. Illustrative chart - not real market data.

In a range the reaction often fades completely. The gap opens, the move looks decisive, and price is back inside the prior range within two sessions — which is the specific pattern that makes chasing an earnings gap expensive.

The second failure is comparing guidance with last year. Consensus is what is in the price.

A third is treating a beat as good news. Against the company’s own conservative bar, it is expected.

A fourth is holding an oversized position through the announcement. No stop protects against a gap.

And a fifth is trading the first minute. The rerating takes days and the initial move is frequently reversed.

The original data

Of the 31,760 trading and investing videos in this site’s corpus, 0 have “earnings guidance” in the title. “Guidance” alone returns 4 at a median of 160 views across 3 channels, and “earnings” returns 28 at a median of 2,375 across 23 channels — against 305 for “dividend” at a median of 7,556. The counts are in research/corpus-coverage.json, produced by site/measure_corpus.py.

A 72-bar window of the shared price history, cut short at the decision bar. The headline on the chart reads: Earnings beat, guidance cut. Which one wins?
Earnings beat, guidance cut. Which one wins? Illustrative chart - not real market data.

A median of 160 views across four videos is what an absent topic looks like. The number that most often decides how a share reacts to earnings is close to untaught on the platform where most people learn about markets, while the results themselves get twenty times the coverage. Read the outlook paragraph before the headline numbers on any release you care about — it is usually two sentences, it is near the bottom, and it is the part the market is actually pricing.

Earnings report is what guidance arrives alongside. Earnings call is where management explains and qualifies it. And 10-Q is the filing that follows the announcement.

What I actually do

The lesson that cost me money was assuming a beat meant a rise. The company reported better numbers than expected, cut its outlook by a few per cent, and the share fell nine. Nothing about that is irrational - the market was already holding the old quarter and repricing the next one.
