A stop order is an instruction to trade once a price is touched. It is not a promise about the price you get. The difference shows up at results time. The announcement lands while the market is shut, and the next print can be well through your level.
When earnings season happens
The calendar is set by filing rules, and the rules differ by market.
In the United States, the SEC requires a quarterly report on Form 10-Q for each of the first three fiscal quarters, containing unaudited financial statements. The fourth quarter is covered by the annual report. So a US-listed company reports four times a year, three of them on Form 10-Q.
In Australia, a disclosing entity lodges a half-year report and an annual report. ASIC requires the half-year report to be lodged within 75 days of the half-year end, and the annual report within three months of the financial year end. Half-year reports must be audited or reviewed.
Reporting clusters because many companies share a fiscal calendar, which is what people mean by "earnings season". Neither the US nor the Australian pattern is the universal one, so check the schedule for the market you trade rather than assuming a quarterly cycle.
The earnings reaction
The price response is to the gap between what was announced and what was already priced. Four things feed it:
- Results against expectations.
- Forward guidance.
- Management commentary on the call.
- What both imply for competitors and suppliers.
A company can report figures above the consensus estimate and still trade lower, if the guidance that comes with them is below what the price assumed. The announcement is not the whole information set.
What an announcement does to option pricing
Cboe's description of the VIX makes the mechanism plain: option prices convey the market's expectation of near-term volatility. An announcement inside an option's life is part of that expectation, and once the results are public the uncertainty those prices covered is resolved.
The consequence for option buyers is that direction alone does not decide the outcome, because the price paid included the uncertainty that has now gone. This article covers stock positions, and the sizing and stop arithmetic below applies to shares.
Opportunities in earnings season
Trading before the announcement
The approach is to trade the structure already on the chart and be flat before the results, which removes the gap entirely.
What it costs you is the move itself. What it buys is a risk you can measure: a stop on a stock trading in normal hours is likely to fill near your level, because there is continuous two-sided trading around it.
Trading after the reaction
The approach is to wait until the results are public and the first session's range is on the chart, then trade the structure that exists afterwards.
This gives up the gap and buys information. The pre-announcement uncertainty is no longer in the price, and the stock now has a fresh reference level in the post-results high and low.
Peer reactions
A large company's results carry information about the demand its competitors and suppliers face. If you hold a peer, the report is an event for your position even though your company is not the one reporting.
Treat it as an exposure you already own rather than a signal to act on. The reporting company's own price move is public within seconds, and the peer trade is a second-order bet on top of it.
Risks in earnings season
Gap risk
Results are usually released outside continuous trading. When the market reopens, the first trade can be well away from the previous close, and a stop sitting in between is filled at the reopening price rather than the level you set.
That is the mechanism people mean by "the stop did not work". The stop worked. The market moved through it while nobody could trade.
Reversal within the session
The first hour after a reaction is not the last word. A gap can be filled the same day, and a session that opens with heavy selling can close higher. If your plan depends on the reaction direction holding, define what would tell you it has not.
Stacked event risk
Two positions reporting on the same day are not two independent risks. If you run five positions at 1% risk each and three of them report on Thursday, you have concentrated three fifths of your open risk into one announcement window.
Four ways to handle a report
Each is a defensible choice. The comparison is what each one costs.
1. Close before the announcement
Give up the move, remove the gap. The re-entry is a fresh decision at a fresh price, and you might not get one.
Suits a trader whose plan cannot absorb an overnight jump.
2. Exit into the announcement from an existing trade
Take whatever the position has done up to the report and close it while the market is open. The difference from the first option is that this is an exit from a running trade rather than a decision to stand aside.
Suits a trader who is already in profit and does not want the position's outcome decided by one release.
3. Enter after the reaction
Wait for the results and the first session, then trade what is there.
Suits a trader who would rather have the announcement behind them before committing, and accepts arriving after the initial move.
4. Hold through with reduced size
Keep the position and accept that the stop may be jumped.
Size it for the gap, not for the stop. If your normal risk is 1% of the account and a gap can plausibly carry price three times your stop distance, the same position size turns a 1% risk into a 3% loss. Cutting the size to a third of normal brings the worst case back to about 1%. The three is a working assumption you choose, not a measurement, so replace it with what that stock has done through past reports.
Suits an experienced trader who has decided the position is worth the exposure and has done that arithmetic first.
Managing earnings risk
Position sizing
Size from the outcome you cannot control. A stop distance sets your risk when trading is continuous; a gap sets it when trading is not. Through a report, the second number is the one that decides the loss.
Stop placement
A hard stop still limits the position, but its fill price during a gap is the reopening price. The line in your plan should say what you accept as a worst case, not what you hope the stop achieves.
Calendar spacing
Check which of your open positions report in the same window and decide whether that concentration is one you would choose deliberately.
Earnings calendar management
Weekly review
Each weekend, write down three lists:
- Holdings and watchlist names reporting in the coming week.
- Positions that need a decision before their report.
- Setups that have appeared from reports already out.
Pre-report checklist
For each position with a report ahead of it:
- The exact date and time of the release, and the session it falls in.
- Your current position size and the dollar risk if the stop fills at your level.
- The same figure if the market reopens 10% away from the close.
- Your decision for each of gap up, gap down and no reaction, written before the day.
Build your earnings playbook
Swingfolio does not predict a reaction, and no journal should. It records what the gaps did to you.
Open a trade, go to its Market tab, and the Overnight Gaps panel shows the gap on your entry day and, while the trade is open, the most recent one. Below that, the holding period is counted: how many overnight gaps went favorable, how many adverse, how many flat, for the direction you were positioned in. That is the record that answers whether holding through announcements has paid you or cost you.
For what is ahead rather than behind, add the Company Events widget to your dashboard. It lists earnings and ex-dividend dates for your open positions inside a window you set, so the report you forgot about is on the same screen as the position it belongs to.
Add the widget, then look back at your last ten trades and count the adverse gaps. Start the 30-day trial and decide your gap policy from your own numbers rather than a rule of thumb.
