AEVEX is trading at $14.29, down 5.61%; no source linked the alert to the October 1 decline. - A September 30 release publicized an existing securities lawsuit and October 20 lead-plaintiff deadline, not a new ruling or company action. - The suit alleges IPO-related lock-up and share-sale disclosure issues. - The Dow fell 0.72%; the S&P 500 and Nasdaq fell less than 0.5%. Broad-market pressure may have contributed, but does not establish the cause.
