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.
