🔴 National Vision is trading 6.05% down in pre-market — catalyst remains unclear

National Vision is trading at $17.28 (-6.05%), with the immediate catalyst unclear.

• No new company-specific announcement, filing, earnings release, or analyst action was found for August 21, 2026.
• The latest identifiable catalyst remains August 12 earnings, when customer traffic declined 4.9% and comparable-sales guidance narrowed to 3%-5%.
• Broader pre-market indexes were positive, so the decline does not appear market-wide.
