Earnings season explained: timing, EPS versus estimates, guidance and gap risk

Earnings season is the stretch of a few weeks, four times a year, when most listed companies publish their results for the quarter that has just ended. In the US it usually begins about two weeks after each calendar quarter closes, with the large banks among the first to report, and the bulk of big companies report over the following four to six weeks. Share prices react to how the results compare with what analysts expected, and especially to what management says about the quarters ahead.

For traders the important practical point is timing. Most US companies release results outside regular trading hours, so the market's verdict often appears as a price gap at the next open. That gap can jump straight over a stop loss, which is why holding a share CFD through an earnings release is a different risk from holding it on an ordinary day.

Why earnings matter to share prices

A share is a claim on a company's future earnings. Analysts and investors spend the quarter building models of what a company will earn, and those expectations are already reflected in the share price. An earnings report is the moment when the company replaces estimates with facts, and when management updates its own view of the future.

The guide to how stock markets work explains that earnings and guidance are among the main drivers of individual share prices. Earnings season concentrates that driver into a few weeks, so it is often the most eventful period of the quarter for single stocks, and it can move stock indices too when the largest constituents report.

When earnings season happens

The quarterly cycle

Most US companies use a fiscal year that matches the calendar year, so their quarters end on 31 March, 30 June, 30 September and 31 December. Results for each quarter then arrive mainly in these windows:

• Q4 and full-year results: mid-January to early March.
• Q1 results: mid-April to mid-May.
• Q2 results: mid-July to mid-August.
• Q3 results: mid-October to mid-November.

Companies with different fiscal years report at other times. Some large technology and retail companies, for example, have fiscal quarters that end a month or two after the calendar quarter, which spreads reports into the "off" weeks.

US public companies also face legal deadlines. Under SEC rules, large accelerated filers (broadly, companies with a public float of 700 million dollars or more) must file their quarterly report on Form 10-Q within 40 days of quarter-end and their annual report on Form 10-K within 60 days of year-end. Most large companies publish a results press release before those filings, usually a few weeks after quarter-end.

Europe and the UK

European companies follow a similar rhythm but with more variety. Many large continental companies report quarterly. In the UK, quarterly reporting stopped being mandatory in 2014, so many UK-listed companies publish full half-year and full-year results, with shorter trading updates in between. A trading update can move a share as much as a full report if it contains a profit warning.

Before the open or after the close

US companies almost always report outside the regular session, which runs from 09:30 to 16:00 New York time. A common pattern is a release around 07:00 to 08:00 New York time for "before market open" reporters, or just after 16:00 for "after market close" reporters, followed by a conference call with analysts. Company investor-relations pages and financial calendars list the date and whether the release is before the open or after the close. Companies usually confirm the date a few weeks ahead; until then, calendars may show an estimated date, so check that it is confirmed.

In UK time, a US pre-market release typically lands around midday to 13:00 London, and an after-the-close release around 21:00 London, depending on the time of year. Our market hours tool shows the sessions in your own time zone.

The numbers the market compares

A full guide to reading an earnings report goes line by line. During earnings season, the first reaction is driven by a handful of comparisons.

Earnings per share versus consensus

Earnings per share (EPS) is net profit divided by the number of shares. The consensus estimate is the average (or median) of published analyst forecasts, compiled by data providers. Headlines report whether a company "beat" or "missed": for example, "EPS of 1.26 versus 1.20 expected".

Two complications matter. First, companies often report an adjusted EPS that excludes items they describe as one-off, such as restructuring costs, and analysts usually forecast the adjusted figure. Comparing the reported (GAAP or IFRS) figure with an adjusted consensus can make a beat look like a miss, or the reverse. Second, many large companies beat consensus most quarters, partly because management tends to guide expectations to a level it is confident of exceeding. A small beat can therefore be treated by the market as roughly "in line".

Revenue versus consensus

Revenue, sometimes called sales or the top line, is harder to flatter with cost cuts or one-off adjustments, so markets watch it closely. A company that beats on EPS but misses on revenue may be cutting costs to protect profits rather than growing, and the reaction can be muted or negative.

Guidance

Guidance is management's own forecast for the next quarter or the full year, often given as a range for revenue, EPS or margins. Many experienced market participants regard guidance as the most important part of the release, because the share price reflects the future rather than the quarter just gone. Raising guidance can lift a share after an ordinary quarter; cutting it can sink a share after a strong one.

The details and the call

Beyond the headlines, analysts look at margins, segment performance, key operating metrics specific to the industry (such as subscribers, same-store sales or deposits), cash flow and comments on demand. The conference call, typically held an hour or so after the release, can move the share again if management says something that changes the picture, so the first price move after the release is not always the last.

Worked example: a beat that falls

Illustrative numbers only. A company reports quarterly results after the close.

• Adjusted EPS: 1.26 against a consensus of 1.20, a beat of 5%.
• Revenue: 9.8 billion against a consensus of 10.0 billion, a miss of 2%.
• Guidance for next quarter: EPS of 1.10 to 1.15, against a consensus of 1.25 for that quarter.

Headlines may read "earnings beat", but the forward guidance is roughly 8% to 12% below what analysts had pencilled in for next quarter, and revenue fell short. Analysts will now cut their forecasts for future quarters, and the share price adjusts to those lower expectations. It would not be unusual for a share in this position to open sharply lower the next day despite the "beat".

The reverse also happens: a company misses on EPS because of a one-off charge but raises full-year guidance, and the shares rise. The lesson is that the headline beat or miss is a poor guide on its own.

Expectations, whisper numbers and implied moves

Priced in

By the time a company reports, the share price already reflects the consensus and often more. If the stock has rallied strongly into the report, investors may be positioned for a big beat, and a merely good result can disappoint. Market slang calls the unofficial, higher expectation a "whisper number". You cannot observe it directly, which is one reason earnings reactions are hard to anticipate.

Implied move from options

For larger US companies, the options market prices in an expected size of move around earnings, often called the implied move. It is derived from the prices of options expiring just after the report and is quoted by many data services as a percentage either way. It is not a forecast of direction, and actual moves regularly exceed it, but it is a useful indication of how big a gap the market considers plausible. The VIX guide explains the related idea of implied volatility for the index as a whole.

Read-across

One company's results can move others. A large chip maker's comments on demand can move other semiconductor shares; a big bank's results can move the sector. Index CFDs can also react when the largest constituents report, particularly on concentrated indices such as the Nasdaq 100. That is worth knowing even if you never trade single shares.

Gap risk for share CFD positions

Share CFDs normally follow the underlying exchange's regular session, as the stock CFDs versus real shares guide explains. If a company reports after the close, the CFD usually cannot be traded until the next open, and it then opens wherever the underlying share opens.

Why a stop loss does not cap the loss

A standard stop loss becomes a market order when its level is touched or passed. If the share opens below your stop, the order is filled at the first available price, which can be far below the level you set. This is a gap, and the shortfall is slippage. The guide to gap risk and weekend risk covers the mechanics in depth for forex; earnings gaps work the same way but are often larger, because a single company's prospects can be reassessed overnight.

Some providers offer a guaranteed stop loss for a premium, which fills at your level regardless of gaps. Availability varies, and some providers do not allow guaranteed stops to be placed or moved shortly before a known event.

Worked example: the stop that was jumped

Illustrative numbers only. You have an account of 40,000 and risk 1% per trade, which is 400. You buy a share CFD at 150.00 with a stop at 144.00, a distance of 6.00 per share.

• Position size: 400 ÷ 6.00 = 66.7 shares, rounded down to 66 shares.
• Exposure: 66 × 150.00 = 9,900. Under the ESMA retail cap of 5:1 for shares, margin is 20% of that, or 1,980.
• Planned risk: 66 × 6.00 = 396.

The company reports disappointing guidance after the close. The share opens at 132.00, a 12% gap. Your stop triggers at the open and is filled at about 132.00.

• Actual loss: 66 × (150.00 − 132.00) = 66 × 18.00 = 1,188, about three times the planned risk and roughly 3% of the account.

Nothing went wrong with the order. The stop did exactly what a stop does in a gap.

Sizing for the gap rather than the stop

If you choose to hold a share through earnings, one approach is to size for the gap you consider plausible. Using the same account and a 400 loss limit:

• If you assume a possible 15% adverse gap from 150.00, that is 22.50 per share.
• Position size: 400 ÷ 22.50 = 17.8 shares, rounded down to 17 shares.

That is about a quarter of the original position. The 15% figure is an assumption for the example, not a ceiling: individual shares have fallen by far more than that on results. Our instruments position size calculator does the arithmetic for any stop or gap distance you choose.

Spreads and liquidity around the release

Even when a share CFD is open for trading, spreads can widen around the release and at the first minutes of the next session, and the first prints after the open can be erratic. The guide to why spreads widen explains the general mechanism. Some providers also raise margin requirements on individual shares ahead of earnings; check your account notices.

Pre-market and after-hours prices

The underlying share often trades in US extended hours immediately after an after-the-close release, so you can watch the reaction even if your CFD is closed. Those prices come from thin trading and can be misleading, as our guide to pre-market and after-hours trading explains. A share that is down 10% after hours can open down 5% or down 15%.

How traders typically handle earnings

There is no single right approach, and none of these removes risk. Common practices include:

• Checking the date before entering. Before opening any share position, look up the next reporting date. Many unpleasant surprises come from not knowing a report was due.
• Closing or reducing before the release. Some traders avoid holding single shares through earnings at all, accepting that they miss the favourable gaps as well as the adverse ones.
• Sizing for the gap. As in the example above, using a smaller position so that even a large gap stays within an acceptable loss.
• Waiting for the reaction. Some traders prefer to wait until the report and the first session are over, then trade the new situation with a known starting point.
• Using index rather than single-share exposure. An index spreads earnings risk across many companies. The index CFD guide covers how those contracts work.

Remember also that leverage magnifies earnings gaps. Share CFDs are capped at 5:1 for retail clients under ESMA rules, but a 20% gap on a position that uses that full leverage would wipe out the entire margin for that position. Negative balance protection limits retail losses to the account balance in the EU and UK, but it protects the account as a whole, not each position.

Earnings season and the wider market

Earnings season has effects beyond single stocks:

• Index moves. When several of the largest index constituents report in the same week, index CFDs can move more than usual. Concentrated indices are more exposed to a few reports.
• Buyback blackout periods. Many companies stop buying back their own shares in the weeks before results, which some market commentators link to slightly different flows around earnings season. The details depend on each company's policy; see our guide to share buybacks.
• Sector rotation. Results and guidance change views on whole industries, which can feed into sector rotation as investors shift money between sectors.
• Macro read-through. Bank results comment on credit and lending; retailers comment on consumers; industrial companies comment on orders. Some traders use earnings commentary alongside economic data, much as forex traders use an economic calendar.

Common mistakes

• Not knowing the date. Opening a short-term share CFD trade the day before a report without realising it is due.
• Judging the result by the headline. A beat on EPS can coincide with a revenue miss or weak guidance, and the share can fall.
• Comparing the wrong EPS figure. Reported and adjusted EPS can differ a lot; make sure you are comparing like with like.
• Assuming the stop limits the loss. In an earnings gap, a normal stop is filled at the first available price.
• Trading the first after-hours print. Thin extended-hours prices can reverse once the conference call is over or the regular session opens.
• Forgetting about leverage. At 5:1, a 20% gap equals the whole margin on that position.
• Treating earnings as a coin toss you can size up for. The outcome is uncertain in both direction and size, which is a reason to size down, not up.

Frequently asked questions

When does earnings season start?

In the US, earnings season usually gets going about two weeks after each calendar quarter ends, so in mid-January, mid-April, mid-July and mid-October, with the large banks among the first to report. Most large companies have reported within about four to six weeks. Companies with non-calendar fiscal years report at other times.

Why did a stock fall after beating earnings estimates?

Because the market reacts to the full picture relative to expectations. Revenue may have missed, guidance for future quarters may have been weaker than analysts expected, or the share may already have risen in anticipation of a bigger beat. Guidance is often the deciding factor, because the share price reflects the future rather than the quarter just reported.

What is the difference between reported and adjusted EPS?

Reported EPS follows accounting standards such as US GAAP or IFRS. Adjusted EPS excludes items that management considers unusual, such as restructuring charges or gains on asset sales. Analyst consensus usually refers to the adjusted figure, so check which one a headline is using.

Can I trade a share CFD when a company reports after the close?

Usually not until the next regular session opens, because most share CFDs follow the exchange's regular hours. Some providers offer extended-hours trading on selected US shares, often with wider spreads. Check the trading hours in your provider's contract specification.

Will my stop loss protect me from an earnings gap?

A standard stop loss will close the position, but in a gap it is filled at the first available price, which can be well beyond your stop level. Only a guaranteed stop, where offered, fills at the exact level, and it usually costs a premium.

How can I find out when a company reports?

The company's investor-relations website is the primary source, and it usually announces the date and time a few weeks in advance. Financial calendars from data providers also list dates, but they sometimes show estimated dates before the company confirms them.
