Thermo Fisher's 0.88% Drop Signals Bearish Reversal After 9.42% Rally Key Support at $538.34 Amid MACD Divergence and Weak Volume-Price Alignment

Thermo Fisher (TMO) closed the most recent session at $539.17, down 0.88%, reflecting a bearish reversal pattern amid heightened volatility. This decline follows a sharp 9.42% surge on October 1, suggesting potential exhaustion in the short-term rally. Key support levels to monitor include the recent low of $538.34 and the 50-day moving average, while resistance is likely clustered around $545.86 (October 6 high) and the 200-day moving average.

Candlestick Theory

The recent price action exhibits a bearish engulfing pattern, with the October 7 candlestick’s body fully engulfing the preceding bullish candle. This signals a potential trend reversal. Additionally, the formation of a "shooting star" on October 3 (high of $545.44) and a "dark cloud cover" on October 6 (closing below the midpoint of the prior bullish candle) reinforces bearish sentiment. Key support levels at $538.34 and $525.36 (September 30 low) may act as critical psychological thresholds.

Moving Average Theory

The 50-day moving average (currently around $534) remains above the 200-day moving average ($528), indicating a bullish intermediate trend. However, the recent price pullback has brought the 100-day moving average ($536) into play as a dynamic support level. The convergence of the 50-day and 100-day averages near $535 suggests a potential consolidation phase. If the price falls below the 50-day average, it could signal a weakening of the bullish bias.

MACD & KDJ Indicators

The MACD histogram has contracted, indicating waning momentum, while the MACD line (currently at -1.5) is below the signal line, pointing to bearish divergence. The KDJ stochastic oscillator shows a death cross, with %K at 28 and %D at 32, suggesting oversold conditions. However, the RSI reading of 38 implies caution, as overbought/oversold levels are not yet extreme. A break below the 30 threshold would strengthen the case for a short-term bounce.

Bollinger Bands

Volatility has expanded recently, with the upper band at $549.44 and the lower band at $538.34. The price’s proximity to the lower band (within 1 standard deviation) suggests oversold territory. However, the narrow band contraction observed in early October (mid-October 5–6) may foreshadow a breakout. A sustained move above the upper band could trigger renewed bullish momentum.

Volume-Price Relationship

Trading volume spiked on October 1 (3.17B) and October 6 (1.39B), aligning with the sharp price swings. However, the recent decline on October 7 (1.01B) occurred on reduced volume, which may indicate a lack of conviction in the bearish move. Divergence between price and volume could hint at a potential reversal if the price stabilizes near key support levels.

Relative Strength Index (RSI)

The RSI stands at 38, hovering near oversold territory but not yet triggering a clear signal. Historical data shows the RSI dipping below 30 in early October, followed by a rebound. If the current pullback continues, a test of the 30 level could provide a high-probability entry for long positions, provided other indicators align.

Fibonacci Retracement

Applying Fibonacci levels to the recent $460–$545.86 range, key retracement levels include 61.8% at $503.6 and 78.6% at $520.3. The current price near $539.17 is approaching the 78.6% retracement level, which could act as a pivot point. A break above $545.86 (100% retracement) would validate a continuation of the bullish trend.

Backtest Hypothesis

The provided MACD Golden Cross strategy, tested from 2022 to 2025, yielded a -8.26% return against the S&P 500’s 45.70% gain. The negative CAGR (-2.33%) and Sharpe Ratio (-0.12) underscore its underperformance. This aligns with the current technical analysis, where MACD divergence and weak volume-price alignment suggest the strategy’s signals may not align with TMO’s fundamentals. The backtest’s poor risk-adjusted returns highlight the need for confluence with other indicators, such as Fibonacci levels and volume patterns, to refine entry/exit points.
