Boeing Stock Plummets 4.4% to $226 Amid Technical Breakdown and Heavy Selling

The Boeing (BA) closed at $226.08, declining 4.37% on July 29, 2025, amid elevated volume of 20.12 million shares. This sell-off breached key technical levels, warranting a multi-indicator assessment.
Candlestick Theory
A bearish engulfing pattern emerged as the July 29 down candle ($225.26–$242.69) completely overshadowed the prior session’s gains. This signals exhaustion near the $243 resistance (July 29 high). Immediate support rests at $225.26 (intraday low), with a breach exposing the $214.72–$220 swing low zone from July 22–23. The $235–$242 range now acts as formidable resistance, aligning with recent distribution.
Moving Average Theory
The 50-day MA (∼$215) was decisively broken during the sell-off, while the 100-day MA (∼$225) is currently being tested. The 200-day MA (∼$195) remains supportive longer-term. This breakdown below short-term moving averages suggests weakening momentum, with the 50/100-day MAs now flipping to resistance. A sustained hold below $225 confirms bearish near-term alignment.
MACD & KDJ Indicators
MACD exhibits a bearish crossover, with the histogram accelerating negatively after peaking in mid-July. KDJ’s %K line (20.4) plunged below %D (42.1), entering oversold territory. While this hints at potential near-term consolidation, both oscillators align in signaling downward momentum. A KDJ reversal above 20 would be required to suggest local capitulation.
Bollinger Bands
Volatility expanded sharply as prices breached the lower band ($228) during the sell-off. This deviation from the 20-day average ($232) indicates panic selling. However, the stretch beyond the lower band may invite a technical rebound. Sustained trading below the lower band would signal continued bearish control, with the middle band ($232) now acting as resistance.
Volume-Price Relationship
Distribution days have increased, most notably the 20.12M volume spike on July 29 – 154% above the 30-day average. This validates the breakdown, confirming institutional outflow. Conversely, the July 9 rally on 16.46M shares was a high-volume accumulation signal. Current volume patterns favor bearish continuation unless accompanied by a high-volume reversal.
Relative Strength Index (RSI)
RSI(14) plunged to 38.6 from 68.1 in seven sessions, exiting overbought territory rapidly. While not yet oversold (<30), the velocity of decline suggests momentum has shifted bearish. A rebound toward 50-55 could attract renewed selling pressure. Divergence would emerge only if RSI stabilizes or rises during further price declines.
Fibonacci Retracement
Applying Fib levels to the rally from $170.06 (March 3 low) to $242.69 (July 29 high) yields key supports: 23.6% ($225.5), 38.2% ($215.2), and 50% ($206.4). The July 29 close near the 23.6% level indicates vulnerability to test $215–$220. Confluence exists at $215, where the 38.2% retracement meets the July 22 swing low.
Confluence & Divergence
Significant confluence supports bearish near-term bias: The breakdown below the 50-day MA and $230 psychological level, confirmed by high-volume selling and bearish MACD/KDJ crossovers. Divergence is minimal, though RSI has not yet reached oversold levels. The $215–$220 zone represents the next critical support cluster, blending the 38.2% Fibonacci retracement, July swing lows, and long-term trend alignment. Recovery above $235 would be needed to invalidate the bearish structure.
