Earnings Calendar & Earnings FAQ

What is an Earnings Calendar?

An earnings calendar is a schedule of when publicly traded companies report their financial results (typically quarterly). It includes:

• Earnings release dates.
• Estimated earnings (EPS forecasts).
• Reported earnings (after release).
• Conference call times.

Platforms like Zacks Investment Research aggregate this information so investors can track multiple companies at once.

Why it matters:
Investors use the earnings calendar to prepare for volatility, compare expectations vs. results, and identify trading opportunities around earnings season.

What are Earnings?

Earnings refer to a company’s profit, usually measured as earnings per share (EPS)—the portion of profit allocated to each outstanding share of stock.

Why companies must report earnings (legal requirement)

Public companies in the U.S. are legally required to disclose financial performance due to:

• SEC reporting requirements (e.g., quarterly 10-Q and annual 10-K filings).
• Fair disclosure rules (Reg FD) ensuring all investors receive material information at the same time.
• Investor transparency obligations.

These rules prevent insider advantages and ensure markets remain fair and efficient.

How can earnings impact stock prices?

Earnings announcements are one of the biggest drivers of stock price movement.

Key ways earnings move stocks:

• Beating expectations → stock often rises.
• Missing expectations → stock often falls.
• Forward guidance (future outlook) can matter even more than past results.
• Revenue vs. profit mix can influence sentiment.

Zacks emphasizes that market expectations (consensus estimates) are critical—stocks react to the difference between expected and actual results, not just the raw numbers.

Volatility factor

Earnings releases often cause:

• Sharp price swings.
• Increased trading volume.
• Options volatility spikes.

Blackout periods (important compliance rule)

Before earnings announcements:

• Company insiders (executives, employees) enter a blackout period.
• They are prohibited from trading company stock.

This prevents insider trading based on unreleased financial results and ensures fairness.

What are earnings surprises and why are they important?

An earnings surprise is the difference between:

• Actual reported earnings.
• Analysts’ consensus estimates.

Types of surprises:

• Positive surprise: Actual results greater than expected.
• Negative surprise: Actual results less than expected.

Zacks tracks these closely and even built a predictive model called Earnings ESP (Expected Surprise Prediction).

Why earnings surprises matter:

• Stocks often move significantly after surprises.
• Positive surprises can trigger rallies.
• Negative surprises can lead to selloffs.

Zacks research shows:

• Stocks with a positive Earnings ESP + favorable rank produced a positive surprise about 70% of the time in backtests.

Key insight:

Companies that have surprised in the past may continue to do so, making earnings surprise history a useful predictive signal.

How to use an Earnings Calendar

An earnings calendar is more than just a schedule—it’s a strategic investing tool.

1. Plan trades ahead of volatility

• Identify upcoming earnings dates.
• Decide whether to buy, sell, or avoid holding through earnings.

2. Compare expectations vs. reality

• Look at consensus EPS estimates.
• Compare with actual results after release.

3. Track trends across sectors

4. Use predictive tools

5. Monitor post-earnings reactions

• Sometimes stocks fall even after strong earnings due to high expectations.
• Focus on market reaction, not just results.
