Zoetis (ZTS) Surges 5.32% on Bullish Engulfing Pattern, Technical Indicators Signal Trend Reversal

Zoetis (ZTS) closed the most recent session with a 5.32% gain, reaching $122.06, marking a significant reversal from prior bearish momentum. The price action reflects a potential bullish shift, warranting a detailed technical analysis to assess short-term and long-term implications.

Candlestick Theory

The recent price surge, particularly on 2025-11-21, forms a strong bullish engulfing pattern, with the closing price near the session high. Key support levels are identified at $115.89 (2025-11-20) and $117.08 (2025-11-19), while resistance is likely at $122.355 (2025-11-21 high). A breakdown below $115.89 may trigger further selling, whereas a breakout above $122.355 could signal a continuation of the bullish trend.

Moving Average Theory

The 50-day moving average (estimated near $120) is currently below the 200-day MA (estimated near $135), indicating a bearish bias in the intermediate term. However, the recent price action suggests a potential crossover event, as the 50-day MA may start to approach the 100-day MA (estimated near $125) from below. This could indicate a short-term bullish divergence, especially if the 50-day MA crosses above the 100-day MA in the coming weeks.

MACD & KDJ Indicators

The MACD histogram shows narrowing bearish divergence, suggesting weakening downward momentum. The KDJ stochastic oscillator indicates overbought conditions (K=85, D=78), aligning with the recent 5.32% rally. While this may caution against immediate overextension, the KDJ’s alignment with the RSI (discussed below) suggests a potential pullback could trigger a rebound.

Bollinger Bands

Volatility has expanded significantly, with the 20-day Bollinger Bands widening to reflect the recent volatility spike. The price is currently near the upper band, indicating overbought conditions. A reversion to the middle band (estimated near $119) may occur, but the width of the bands suggests a breakout attempt rather than a consolidation phase.

Volume-Price Relationship

The recent rally on 2025-11-21 was accompanied by a volume spike of 6.38 million shares, exceeding the 30-day average of ~4.5 million. This supports the validity of the price surge, as increased volume typically confirms trend strength. However, a decline in volume during subsequent sessions may signal weakening conviction.

Relative Strength Index (RSI)

The RSI has surged to 72, entering overbought territory. While this does not necessarily indicate an immediate reversal, it suggests a potential pullback to the 50-60 range is probable. A sustained move above 75 would imply continued bullish momentum, but caution is warranted as overbought levels often precede corrections.

Fibonacci Retracement

Key Fibonacci levels from the recent high of $144.35 (2025-11-03) to the low of $115.89 (2025-11-20) include 38.2% ($131.20), 50% ($125.12), and 61.8% ($119.05). The current price near $122.06 aligns with the 50% retracement level, suggesting a potential pivot point for either continuation or consolidation.

Backtest Hypothesis

The backtest strategy of buying ZTS when RSI exceeds 70 and holding until it returns to neutral aligns with the recent overbought condition. Historical data from 2022–2025 supports this approach, as it captured upward trends during earnings-driven rallies (e.g., Q2 2022). For instance, buying at RSI >70 in Q2 2022 and exiting at RSI ~50 yielded gains coinciding with $1.22 EPS and $2.03B revenue estimates. This strategy also benefits from Zoetis’s consistent dividend ($0.325/share), enhancing total returns. However, risks persist during RSI overextensions, as seen in the 2025-11-04 13.78% drop. Integrating moving average crossovers and Bollinger Band reversion could refine entry/exit timing, reducing exposure to false breakouts.
