How often are grades updated?
Using MaegimLast updated
Every stock is re-scored once per business day. Financials automatically incorporate new and corrected annual-report filings, and prices use the latest confirmed figures from the public API. The as-of date is displayed alongside each grade so you always know which day's data you are looking at.
That said, a buffer zone keeps grades from flipping day to day when the total score hovers near a boundary, so it is normal for the grade itself to change infrequently even though the data refreshes daily. When a grade does change, the change is recorded in the stock's history along with its previous grade and the type of reason.
