About AFTERNS

See the probability of a next-day gain, average move on earnings day, reaction versus consensus beats and misses, guidance reaction, and the next scheduled earnings date at a glance. We analyze the price-vs-results mismatch — where a stock can fall even on strong earnings — for each stock.

Frequently asked questions (FAQ)

What is afterns?

AFTERNS (short for “After Earnings”) It shows how each US-listed stock (1,200+, including the S&P 500) moved right after its earnings announcements, with a 3-year (about 12-quarter) timeline and statistics: next-day gain probability, average move on earnings day, reaction versus consensus beats/misses, guidance reaction, and the next earnings date.

Does a stock go up when earnings are good?

Not always. Nearly half the time a stock falls even after beating consensus, because the market reacts to guidance and already-priced-in expectations, not just the reported number. We analyze this pattern per stock.

How can I check a US stock's next earnings date?

Each stock page shows the next scheduled earnings date, days remaining (D-day), whether it reports before or after market, and the consensus EPS estimate. The 'Upcoming' tab on the home page groups stocks reporting soon.

How much does a stock usually move the day after earnings?

It varies by stock. We show each stock's average earnings-day move, its largest single reaction, and next-day gain probability. Large caps typically move ±3–5%, while volatile names can move double digits.
