Was ALKS'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.

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.
