Cognyte Software is trading at $8.27 (-5.21%) after the October 19 regular-session close; no verified new company-specific catalyst explains the after-hours decline. - An approximately $20 million EMEA expansion agreement appeared in October 19 search results, but it was previously announced and does not establish a reason for the move. - Major U.S. indexes were higher in the supplied market context, so broad market weakness does not explain the decline; the reason remains unclear.
