Zoetis is trading 6.4% down at $69.27 after the broader market sold off on August 18, 2026.
- Technology-led weakness, rising Treasury yields, higher oil prices and geopolitical uncertainty weighed on risk assets.
- The S&P 500 fell 0.69%, while the Nasdaq Composite declined 0.79%.
- Zoetis’s August 6 guidance reduction and softer pet-health demand remain important company-specific pressure, but no new August 18 company announcement was identified.
