Amphenol Surges 5.6% to $116.79 as Technicals Signal Bullish Breakout

Candlestick Theory
Recent Amphenol price action shows a strong bullish reversal, with the September 9 session forming a large bullish candle (open: $110.60, close: $116.79) on high volume. This follows a hammer pattern near $108.65 (August 20 low), confirming support. Resistance is evident near $117.24 (July 24 peak and September 9 high), while $112.75 (September 4 close) now acts as immediate support. The consecutive higher closes after testing $108.68–$110.45 (September 5–8) signal renewed buyer conviction.
Moving Average Theory
The 50-day MA (~$104) crossed above the 100-day MA (~$98) in late August, followed by a golden cross above the 200-day MA (~$90), confirming a long-term bullish trend. Current price ($116.79) trades significantly above all three MAs, though the widening gap may indicate short-term overextension. The alignment of all MAs in ascending order underscores sustained upward momentum.
MACD & KDJ Indicators
MACD (12,26,9) shows a bullish crossover emerging above the signal line, with the histogram turning positive—suggesting increasing upward momentum. KDJ (14,3,3) resides in overbought territory (K: 85, D: 78, J: 99), indicating near-exhaustion of buying pressure. While MACD supports continuation, KDJ’s overbought reading raises caution for potential pullback risks.
Bollinger Bands
Volatility expanded sharply during the September 9 rally, with price touching the upper band ($117.24). The bands had previously narrowed in late August, foreshadowing the breakout. Sustained trading near the upper band signals strength, but a close below $115.30 (mid-band) may trigger a mean-reversion dip.
Volume-Price Relationship
The September 9 surge occurred on 14.1M shares—56% above the 3-month average—validating bullish conviction. Recent advances (e.g., September 3–4, August 28) consistently saw above-average volume, while pullbacks (September 5, August 29) occurred on lower volume, confirming healthy accumulation.
Relative Strength Index (RSI)
The 14-day RSI (66) is neutral but rising, avoiding overbought (>70) territory despite the sharp rally. This divergence from KDJ’s overbought signal suggests room for further upside before exhaustion. RSI would only signal caution if it exceeds 75 without price consolidation.
Fibonacci Retracement
Applying Fib levels between the July 24 high ($117.24) and August 20 low ($108.65):
- The 61.8% retracement ($114.05) was surpassed on September 9, confirming strength.
- Current resistance aligns with the 78.6% level ($116.79), coinciding with the July 24 peak.
- Holding above $112.75 (38.2% retracement) is critical to maintain bullish bias.
Confluence & Divergence Notes
Confluence:
- Multiple resistances converge near $117.24 (historical high, Bollinger upper band, Fib 78.6%).
- Support at $112.75 combines Fib 38.2%, prior resistance, and the 10-day MA.
Divergence:
- KDJ’s overbought signal conflicts with RSI neutrality and MACD momentum, suggesting short-term consolidation may precede further gains. Volume-backed price action currently favors the bullish outlook.
In summary, Amphenol exhibits robust bullish momentum with key resistance at $117.24. While indicators like KDJ hint at overextension, volume support and multi-timeframe trend alignment suggest dips to $112.75–$114.05 may present buying opportunities. A sustained break above $117.24 could accelerate gains toward $120.
