Was ASPN's earnings move already priced in?
Stocks often move in the weeks before a report. This compares that run-up with what happened after the report.
“Month before” is the move over the 20 trading days up to the last close before the report. “Priced in” means the good news may already be in the price. A run-up of 5% or more is treated as large.

Does ASPN hold its opening gap after earnings?

Answers computed from ASPEN AEROGELS INC's reported history
ASPN is scheduled to report on Oct 22, 2026, usually before the market opens. Analysts expect EPS of -$0.08.
Over the last 11 quarters with a usable EPS surprise, ASPN beat the consensus estimate 8 times (73%), missed 3 and landed in line 0. It has missed estimates in each of the last 3 counted quarters.
Across its last 11 quarters with a measured reaction, ASPN moved an average of ±26.3% in the first session after reporting. It closed higher 55% of the time; the largest gain was 56.7% and the largest drop -44.5%.
ASPN fell in the first session after 3 of its last 7 EPS beats (43%). A beat that was already priced in, or weaker guidance, can send a stock lower. In 3 of the 3 of those falls where price data is available, the stock had already risen before the report.
Across its last 11 quarters with price data, ASPN moved an average of -1.2% in the 20 trading sessions before reporting and was higher in 36% of them. After a run-up of 3% or more (4 quarters), it fell the next day 50% of the time, averaging +0.8%. After a drop of 3% or more (6 quarters), it rose the next day 67% of the time, averaging +9.6%. This describes past reports; it is not a forecast.
In 11 reports ASPN opened at least 1% away from the previous close. It gave back half or more of that gap by the close 1 of 11 times (9%), and fully reversed once. A fade means the opening move was partly undone during the first session.
How we calculate these numbers
Reported EPS and estimates come from Yahoo Finance; report times, upcoming dates and revenue come from Finnhub. The 1-day move is the close-to-close change over the first session that reflects the report (the report-day close for after-close reports, the prior close for pre-market reports); reactions are left blank when the report time is unknown or looks inconsistent. The expected move is the price of the nearest at-the-money straddle that expires after the report divided by the share price, shown only when the quotes are liquid. Quarters where the two data sources disagree on beat versus miss are shown but never counted. Information only, not investment advice.
