Earnings day is the day, up to 4 times a year, when your stop-loss may not work. If a company reports after the close and the stock opens 15% lower, your stop 5% below the price does not fill at 5%. It fills at the open, and the gap is yours.

So should you hold a stock through earnings? You can, if the position is small enough that the worst likely gap is a loss you already accept. If it is not, trim it to that size or close it before the report. That is the whole decision, and the rest of this post shows how to measure it.

Why does a stop-loss fail on earnings day?

Because the price jumps over it. A stop-loss is an order that triggers when the price trades at or through your level. When a stock closes at one price and opens far below it, there is no trade in between for your order to catch. The stop triggers at the open and fills at the next available price, which can be far below where you set it.

Here is what that does to a position with a stop 5% below the entry. The 5% is your planned risk, or 1R.

A 3R loss is 3 normal losing trades in one night. If your plan risks 1% of the account per trade, that is 3% of the account. Nothing you did was wrong. The order simply could not fill at the level you chose.

If you are not sure where your stop should sit on a normal day, where to put your stop-loss and take-profit covers that first.

What is the gap test?

It is 3 questions I ask about any open position with a report coming up. I call it the gap test.

1. How far has this stock moved on its last few earnings days? Open the daily chart and find the last 8 reports. Note the move from the prior close to the next open each time. The biggest one is your working worst case.
2. What would that gap cost me, in R? Divide the worst gap by your stop distance, so a 15% gap on a 5% stop is 3R.
3. Can I take that loss without changing my plan? If the answer is yes, you can hold. If it is no, cut the size until the answer is yes, or close.

The test works because it swaps a guess about the result for a measurement of the risk. Nobody knows which way the report will go. You can know what a bad night costs.

How do you size a position for an earnings gap?

Size it for the gap. Normal position sizing divides your risk per trade by your stop distance, and through earnings you divide it by the gap you measured.

Say you risk 1% of the account per trade, with a 5% stop. The normal position is 1% ÷ 5%, or 20% of the account. Now the last 8 reports show a worst gap of 15%. To keep a 15% gap to a 1R loss, the position becomes 1% ÷ 15%, or about 6.7% of the account.

That is what trimming means in practice. The position shrinks to the size it would have been if the stop were as wide as the gap, and the report can go either way.

Should you hold, trim or close?

Each choice has a cost, so here they are side by side.

• Hold at full size. You keep the whole upside of a good report. You also carry the whole gap, and a few of those in a row can do lasting damage. Risk of ruin shows how quickly a string of oversized losses compounds.
• Trim to gap size. You keep part of the upside, and the worst night costs about 1R. This is the middle road, and the gap test tells you how much to cut.
• Close before the report. You carry no gap at all. You also miss every good gap, and some of those are the biggest moves the stock makes all year.

Personally, I close or reduce a swing position when earnings fall within about 5 to 6 days. My trades are built on a chart setup and a stop, and a report can jump the price past both overnight. So I would rather give up the good gaps than hold a trade my stop cannot protect. That is a choice that fits my plan, and a longer-term investor holding a business for years has every reason to choose differently.

Do options make holding through earnings safer?

Not automatically. Options add a second risk on earnings day, called IV crush.

Before a report, traders pay more for options because a big move is expected. That extra price is implied volatility. Once the report is out, the uncertainty is gone, and implied volatility usually drops at once. So an option can lose value even when the stock moves the way you expected.

A trader on r/options put it well in September 2026, in a post titled “I’m right but I lose money.” Their words: “My event driven option trades (earnings report) are correct… IV crush completely kills my trade.” One reply was blunt: “If you’re good at getting the direction correct, you should just trade shares instead so you don’t have to deal with IV crush.”

Options can still cap a gap. A bought put limits how much a share position can lose, for a known cost. How that pricing works is in the Greeks in plain English, and the wider toolkit is in the options trading guide.

How often do Singapore companies report earnings?

Usually twice a year, and that changes the risk. Most US-listed companies report every quarter. On SGX, the current rule lets most companies report half-yearly.

SGX Mainboard Rule 705(3)(b) says a listed company “must either: (i) announce the financial statements for each of the first three quarters… or (ii) announce its first half financial statements”. The full-year numbers must come out “not later than 60 days” after the year ends. Quarterly reporting is only required when the auditors have flagged a problem, such as a qualified opinion or doubt about the company as a going concern.

So an SGX stock that reports half-yearly has 2 earnings days a year where a US stock has 4. Each one can carry 6 months of news. The gap test still applies, and it may matter more, because the gaps can be wider when news builds up for longer.

For how SGX trades settle and what happens to dividends and other corporate actions, see how SGX trading works.

Is there a way to trade earnings without holding through them?

Yes. You can wait for the report and trade the reaction. A stock that gaps up on strong results and holds the gap through the first few days is telling you something about demand, and some swing traders build a whole setup around that. The trade starts after the uncertainty, so the stop sits below a known price, and a normal stop works again.

You give up the first jump. In exchange, your stop goes back to being a real limit on your loss. Finding those stocks in the first place is the job of a screener, covered in how to find stocks to swing trade.

Where does the earnings risk really sit?

The open. Everything you plan happens at the close, and everything you risk on earnings day is decided at the open. A stop-loss only limits your loss when the price trades through it, so on the few mornings a year when it may not, the size of the position is your only real stop.

Which of your open positions has a report in the next 2 weeks, and do you know what its last gap was?

FAQ

Should you hold stocks through earnings?

You can, if the position is sized so that the worst recent earnings gap costs no more than a loss you already accept. If it would cost more, trim to that size or close before the report.

Does a stop-loss protect you on earnings day?

Only if the price trades through it. If the stock gaps past your stop at the open, the stop fills at the next available price, which can be far below your level.

How much should you trim before earnings?

Divide your risk per trade by the stock’s worst recent earnings gap, in place of your stop distance. With 1% risk and a 15% worst gap, the position is about 6.7% of the account.

Why do options lose value after earnings even when I am right?

Implied volatility usually falls right after the report, which is called IV crush. That fall can take more value out of an option than the stock’s move adds.

How often do SGX companies report earnings?

Under SGX Rule 705, most Mainboard companies may report half-yearly, with full-year results due within 60 days of the year end. Quarterly reporting is required only after certain audit flags.
