Zoetis is trading at $78.44, up 4.19%, as healthcare shares gain in a defensive rotation. - Investors are responding to hotter-than-expected inflation data and a risk-off market backdrop. - No clear company-specific announcement explains the October 15 move; recent board and dividend news appear secondary. - XLV was up 2.12% while the broader market was mixed; reporting supports sector strength but does not establish a unique Zoetis catalyst.
