Coherent Jumps 5.29% on Bullish Candle Breakout and MA Crossover

Coherent (COHR) surged 5.29% in the latest session, closing at $194.33, amid elevated trading volume. This sharp rally follows a volatile period marked by significant swings, including a -10.16% decline on 2025-12-12 and a subsequent rebound. Candlestick Theory suggests a potential reversal setup as the recent bullish candle pierced above key resistance levels (e.g., $190.98 on 2025-12-22). Key support levels include the 2025-12-12 low ($178.34) and the 2025-12-17 trough ($170.44), while resistance aligns with the 2025-12-18 high ($187.12) and the 2025-12-19 peak ($187.83). A bullish engulfing pattern on the 2025-01-02 session further reinforces short-term optimism, though a bearish divergence in the KDJ indicator (Stochastic) near overbought territory may hint at near-term profit-taking.
Moving Average Theory reveals a bullish alignment, with the 50-day MA (approx. $182.50) and 100-day MA ($175.00) crossing above the 200-day MA ($168.00), signaling a strong uptrend. The 200-day MA has historically acted as dynamic support, most recently during the 2025-12-12 selloff. However, the 50-day MA now risks becoming a liquidity trap if the price fails to sustain above $190.00, which would trigger a retest of the 100-day MA.

MACD & KDJ Indicators show mixed signals. The MACD (12/26/9) crossed above the signal line with a histogram expansion, confirming bullish momentum. Conversely, the KDJ indicator entered overbought territory (85.00 for %K), suggesting a potential pullback. A bearish divergence between the KDJ and price action—where the %K line flattened despite a new high—heightens caution, though the MACD’s strength implies the uptrend may persist.
Bollinger Bands highlight elevated volatility, with the 20-period bands expanding to $187.02 (lower) and $195.92 (upper). The current close near the upper band ($194.33) suggests overbought conditions, but the absence of a break above the 2025-12-19 high ($187.83) indicates the bands may contract soon, reducing short-term volatility. A sustained break below the 20-day MA ($189.00) would signal increased bearish risk.
Volume-Price Relationship validates the recent rally, with volume surging to 3.4 million shares on the 2025-01-02 upsession. However, volume has since declined, raising questions about the sustainability of the move. Historically, volume spikes during sharp rallies (e.g., 7.3 million on 2025-12-12) often precede corrections, suggesting caution if volume remains muted during further advances.
RSI (14-period) stands at 72.00, indicating overbought conditions. While the RSI has historically diverged from price during prior peaks (e.g., 78.50 on 2025-12-19), the current level remains within the bounds of a strong uptrend. A close below 60.00 would confirm a near-term correction, but the RSI’s alignment with the MACD suggests the trend may hold.
Fibonacci Retracement levels derived from the 2025-12-12 low ($178.34) to the 2025-12-19 high ($187.83) highlight critical confluence at 61.8% ($184.00) and 78.6% ($187.00). The current price near $194.33 exceeds the 100% extension, suggesting a potential retracement to the 78.6% level before resuming the uptrend.
Confluence between the 50-day MA, Fibonacci 78.6% level, and Bollinger Bands contraction suggests a key inflection point. While the MACD and RSI support continued strength, the KDJ divergence and declining volume imply short-term caution. A break above $195.00 would validate the bullish case, while a close below $184.00 would signal increased bearish risk.
