How Do Earnings Reports Affect Stock Prices? EPS, Guidance and Gaps

Earnings reports affect stock prices by changing what the market expects a company to earn, so prices react to results and guidance versus forecasts, not to profit alone. Because many reports land outside regular trading hours, a stock CFD can open at a very different price from its last close.

What you'll learn

What is an earnings report?

An earnings report is a company's regular announcement of its financial results for the latest quarter or year: how much it sold, how much profit it made and, often, what it expects next. Listed companies publish them on dates set in advance, and the share price, and any CFD on that share, can react sharply when they land.

In the United States, they are formal filings with the Securities and Exchange Commission (SEC), whose investor site explains that domestic companies file annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K.

Filing What it is When
Form 10-Q Quarterly report with unaudited financial statements For each of the first three quarters of the company's financial year
Form 10-K Annual report Once a year
Form 8-K Current report on major events, including results press releases When a reportable event happens

Many companies first announce results in a press release, filed with an 8-K, and hold an earnings call soon after. The SEC's guide to reading an 8-K notes that the full financial statements follow later in the 10-Q or 10-K.

Earnings call: a conference call where managers discuss the results and answer analysts' questions.

How do earnings reports affect stock prices?

Earnings reports affect stock prices by changing what investors expect a company to earn in future. Before a report, the share price already reflects a forecast. When results and the company's outlook come in better or worse than that forecast, buyers and sellers reprice the share, sometimes by a large amount in one move.

This is why a profitable company's share can still fall on results day: the market asks whether results beat expectations, not whether the company made money. The same idea, that prices react to surprises, is explained in what makes prices move in trading.

What are an earnings beat and an earnings miss?

Traders often read the result and the guidance together:

EPS versus estimate Guidance How traders often read it
Beat Raised Positive, unless already priced in
Beat Cut Mixed: the weaker outlook can outweigh the beat
Miss Raised Mixed: the better outlook can soften the miss
Miss Cut Negative

The reaction also depends on what was already priced in, so traders weigh each result against the expectations built into the price.

What is EPS (earnings per share)?

Earnings per share (EPS) is a company's net profit for a period divided by the number of its shares. The SEC's beginners' guide to financial statements describes it as what shareholders would receive for each share if all the period's net income were paid out.

EPS = net income ÷ number of shares outstanding

Example with synthetic figures: Company A earns net income of $134 million in a quarter and has 100 million shares, so EPS is $134 million ÷ 100 million = $1.34.

Which figures matter most in an earnings report?

The figures traders read first are revenue, earnings per share and guidance, each compared with what analysts expected. Revenue shows whether sales are growing, EPS shows profit per share, and guidance shows what management expects next. Together they show whether the business is meeting the expectations built into its share price.

Figure What it measures What it is compared with
Revenue Total sales in the period Analysts' revenue estimate and the same quarter last year
EPS Net profit per share Consensus EPS estimate
Guidance The company's own forecast for coming quarters or the full year The previous guidance and analysts' forecasts

Why can guidance matter more than the quarter?

Guidance can matter more than the quarter because the quarter is already over, while guidance changes expectations for every quarter still to come. A share price reflects what investors think a company will earn in future, so a lowered forecast can outweigh a better-than-expected past quarter.

Guidance: a company's own forecast of future results, such as expected full-year EPS or revenue. A company can raise or lower it as the year goes on.

Scorecard of an earnings report: EPS of 1.34 against an estimate of 1.20, guidance cut from 5.00 to 4.50, and the share price gapping lower after the release
  1. EPS beat the estimate: $1.34 against $1.20.
  2. Full-year EPS guidance was cut, from $5.00 to $4.50.
  3. The share price opened sharply lower after the release, despite the beat.

Why do stock CFDs gap after earnings?

Stock CFDs often gap after earnings because many companies release results outside regular trading hours, when the main market is closed. When trading resumes, the price jumps straight to a new level that reflects the news, with no trading at the prices in between. A CFD on that share follows the jump.

Earnings from the largest US companies also feed into index CFDs, as the US30 Dow Jones guide explains.

Regular US stock trading hours are 9:30 a.m. to 4:00 p.m. Eastern Time. The SEC's bulletin on extended-hours trading notes that companies may announce important news outside these hours, which may lead to significant price changes.

Gap: a jump between one price and the next with no trading in between. A share CFD tracks the underlying share's price, as explained in what is a CFD, so it inherits the gap.

How does an earnings gap affect a stop loss?

An earnings gap can make a stop loss close a trade well past its level, because the price jumps over the stop and the order fills at the first available price. As ASIC's CFD guide explains, a standard stop loss may not be executed at the price you set; only a guaranteed stop fixes the exit price.

Worked example with Company A (synthetic):

  1. Before the report, Company A's share closes at $100. You hold a CFD long of 50 shares, opened at $100, worth $5,000.
  2. Your stop loss is at $96, so the loss you planned for is 50 × $4 = $200.
  3. After the close, Company A beats its EPS estimate ($1.34 against $1.20) but cuts its guidance.
  4. The share opens at $92, an 8% gap. No price traded between $100 and $92.
  5. Your stop triggers at the open and fills near $92. The loss is 50 × $8 = $400.
Planned Actual
Exit price $96 about $92
Loss per share $4 about $8
Loss on 50 shares $200 about $400

The stop did not fail; it limited the loss to the first price available. The stop loss and take profit lesson explains how standard and guaranteed stops fill, and the position size calculator helps you work out a size that keeps a realistic gap within your plan. Sizing for gap risk is part of position sizing.

How do dividends and corporate actions affect a stock CFD?

When the underlying share pays a dividend, a stock CFD position is usually adjusted in cash: a long position is credited and a short position is debited. ASIC's guide explains that buying a CFD credits an amount mirroring the dividend, while selling one debits a similar amount.

Other corporate actions, such as a share split, can also lead your provider to adjust a position's size or price. Your broker's terms set how and when, so check them before holding a share CFD through a company event.

How do you manage stock CFD trades around earnings?

To manage a stock CFD through earnings, size the position for a realistic gap, not just for your stop distance, because the price can open beyond your planned exit. Leverage applies the gap to the whole position, not just your margin, and thinner liquidity outside regular hours can mean wider spreads.

Frequently asked questions

Why do stocks fall after good earnings?

Stocks can fall after good earnings when the results were already expected or when guidance for future quarters is weaker. The price reflects expectations, so a beat that was priced in, or a cut to the outlook, can still push the share lower.

When is earnings season?

Earnings season is the few weeks after each quarter ends, when many listed companies release results on dates they announce in advance. The SEC's Form 10-Q instructions (revised February 2025) give larger US companies 40 days after the quarter ends to file, and others 45 days. Many results land before the market opens or after it closes.

What is a good EPS?

A good EPS is one that beats the consensus estimate and grows on the same quarter a year earlier. The raw figure depends on the company's size and number of shares, so traders judge it against those two benchmarks rather than in isolation.

Do you get dividends on a stock CFD?

You do not receive a dividend as a shareholder, because a CFD does not give you the share. Instead, providers usually make a cash adjustment: long positions are credited and short positions are debited. Check your broker's terms for the timing and amount.
