The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

https://www.sciencedirect.com/science/article/pii/... examined weighting momentum by days where it was most significant, citing earnings announcement days

Bespoke reports
bespokepremium.com - Volatile stocks in reaction to earnings
Stocks that move big on earnings announcement days (MUST have 2.5 years worth of announcements,>$5 price; typically move up or down 11.75%) move the most

Zacks uses a measure "EarningsEPS" that claims that stocks with a strong reaction to the difference between the consensu and the most sensitive, accurate estimates move the most.
