Zoetis Plunges 3.83% Amid Volatile Reversal—What’s Fueling the Selloff?

Summary
• Zoetis (ZTS) opens at $160.02, plunges to $145.14 intraday
• 52-week high of $200.33 remains distant amid bearish RSI (48)
• Options chain shows ZTS20250815P140 (Put) with 235.79% leverage and 26.96% IV
• Sector leader Medtronic (MDT) up 0.02% as ZTS underperforms healthcare peers

Zoetis’ dramatic 3.83% drop has sent shockwaves through the healthcare sector, with the stock trading near its 52-week low of $139.7. Despite a Q2 earnings beat and raised guidance, the stock’s sharp reversal from a premarket high of $162 to a post-open low of $145.14 highlights intense short-term volatility. Technical indicators and options activity suggest a critical juncture for the stock, with key support/resistance levels and leveraged options contracts offering clues to its near-term trajectory.

Q2 Optimism Collides With Arthritis Setback and Profit-Taking
Zoetis’ intraday collapse follows a mixed bag of news: while the company reported a Q2 beat with $1.76 EPS and $2.46B revenue, raising its full-year guidance to $6.30–$6.40/share, the market reacted to lingering concerns over its arthritis drug pipeline. A Reuters report highlighted that Zoetis’ pain and dermatology drugs like Librela and Apoquel face regulatory and competitive headwinds, dampening long-term growth expectations. Additionally, the stock’s 7% premarket surge on earnings optimism triggered aggressive profit-taking, with short-sellers capitalizing on the overbought RSI (48) and bearish MACD (-2.46) to drive the reversal. The 52-week low of $139.7 now looms as a critical psychological threshold.

Healthcare Sector Mixed as Medtronic Holds Steady
While Zoetis tumbles, the broader healthcare equipment & supplies sector remains resilient, with Medtronic (MDT) up 0.02% and the S&P 500 Healthcare Index flat. This divergence suggests Zoetis’ selloff is stock-specific rather than sector-wide. Medtronic’s stability underscores investor confidence in established medtech players, contrasting with Zoetis’ exposure to volatile animal health markets and regulatory risks. The sector’s 7.53% weight in the S&P 500 indicates limited spillover risk, but Zoetis’ 25.75 P/E ratio remains elevated relative to peers like Becton Dickinson (BDX) at 22.5 P/E.

Options Playbook: Leverage Put Spikes and Call Theta Decay
• 200-day MA: $165.12 (below current price) • RSI: 48 (neutral) • MACD: -2.46 (bearish) • Bollinger Bands: $144.72–$159.38 (current price near lower band)

Key Levels: Watch $145.14 (intraday low) and $152.05 (20-day MA). A break below $144.72 (lower Bollinger Band) could trigger panic selling. Short-term bulls may target a rebound above $153.86 (30-day MA), but the 200-day MA at $165.12 remains a distant hurdle.
