Apple's February 1, 2024 announcement said "first quarter." The quarter had ended in December. JPMorgan's January report said "fourth quarter." You want to add an earnings reminder to your calendar, and even the quarter labels disagree.
Save the period end and you'll be more than a month early for Apple's news. Save only the conference call and the results may already be out. Your reminder needs the announcement date, whatever quarter the results describe.
Two dates, two different jobs
Earnings season is a busy window when many public companies announce their financial results. It has no official opening bell. Each company has its own reporting schedule.
A fiscal year is a company's accounting year. A fiscal quarter is one of its four parts, each about three months long. Q1 means the first part of that company's year; it does not have to mean January through March.
The year can end in a month other than December. Some businesses, including retailers, use 52- or 53-week years to keep reporting periods in whole weeks.
The period end is the last day included in the results. The release date is when the company plans to publish them. The business clock keeps running while you wait for the news.
The earnings call is management's discussion of the results, with its own start time. The periodic financial filing may arrive with the release or later. These are separate events, even when they share a date.
How a reporting season unfolds
Many US companies with December year-ends report in four broad waves:
- January–February: results for the quarter ended in December.
- April–May: results for the quarter ended in March.
- July–August: results for the quarter ended in June.
- October–November: results for the quarter ended in September.
These are busy stretches, not deadlines. Companies with different fiscal calendars can report outside them. Large banks often report early in a season, but no company has a permanent place at the front.
An estimated earnings date is a calendar provider's best guess, often based on past reporting dates. A confirmed earnings date is one the company has announced. Its investor-relations page is where you check which you have.
An estimate is a placeholder, not an appointment.
Read the notice's release time and time zone, then check the call time separately. "Before the open" and "after the close" refer to the regular trading session. In another time zone, the same announcement can fall on a different calendar date.
Why the date can move the price
An earnings release puts new evidence in front of investors at the same time. They reassess what the shares are worth, and their buying and selling can move the price sharply in either direction. Sometimes the price barely moves.
Results are judged against expectations; beats and misses explain that comparison. The calendar tells you when the news is due, not which way the stock will go.
Trading outside regular market hours brings the extra risk of fewer buyers and sellers. The news can keep coming after the headline: the call can clarify a result, and a later filing can add detail.
A real winter reporting window
JPMorgan Chase and Apple both reported results in the winter of 2024. JPMorgan's year ended in December; Apple's ended in September. The same reporting season held JPMorgan's Q4 2023 and Apple's fiscal Q1 2024.
The lag is calculated from the dates in Apple's release:
February 1, 2024 − December 30, 2023 = 33 calendar days.
That includes weekends. Apple's next quarter was already more than a month old when investors got the last quarter's results.
Apple also reported 13 weeks in fiscal 2024 Q1, compared with 14 in fiscal 2023 Q1. That is one less week of business under the same "Q1" label. Equal quarter labels do not guarantee equal time to make sales.
JPMorgan's December 12, 2023 scheduling notice and January 12 results give us the three fields an earnings reminder needs:
The reminder separates the business period from the release and the call. Once the results arrive, you are ready to read the earnings release. Nothing in that calendar entry requires a trade.
In short
- The earnings date is when results become public; the period end marks the last day they cover.
- Q1 means the start of the company's fiscal year, which need not begin in January.
- Confirm the release time and time zone with the company, and keep the call time separate.
- A known announcement date helps you prepare for information, not predict a price move.
