🟢 Vivani Medical is trading 5% up today; no clear catalyst identified

Vivani Medical is trading 5% up at $1.42, based on live price context for August 18, 2026; the stock-specific gain remains unexplained.

• No major company-specific announcement dated August 18 was identified.
• Recent updates include the Novo Nordisk evaluation agreement and August 13 earnings and trial-progress disclosures; neither is sufficiently contemporaneous to establish causation.
• The broader market is weaker, so the gain appears stock-specific but unexplained.
