Broadcom Stock Surges 4.09% as Bullish Engulfing Pattern Emerges, Eyes $359.69 Resistance

Candlestick Theory

Broadcom’s recent price action shows a strong bullish bias, with the stock surging 4.09% on November 19, 2025, closing at $354.42. This follows a prior session’s bearish reversal pattern (a long upper shadow on November 18, closing at $340.5), suggesting a potential short-term bottoming process. Key support levels are evident around $340.5 (November 18 close) and $335.51 (November 17 low), while resistance clusters near $354.42 (recent high) and $359.69 (November 19 high). A bullish engulfing pattern on November 19 confirms renewed buying momentum, but a test of the $359.69 level is needed to validate breakout sustainability.

Moving Average Theory

The 50-day moving average (calculated from historical data) appears to be rising, aligning with the 100-day and 200-day averages, which are also trending upward. This confluence suggests a medium-term bullish trend. However, the 50-day MA is currently within 3% of the 200-day MA, indicating a potential narrowing of the uptrend’s momentum. Short-term traders may monitor crossovers for entry/exit signals, while long-term holders should watch for a “Death Cross” (50-day MA crossing below 200-day MA) as a bearish warning.

MACD & KDJ Indicators

The MACD histogram has expanded positively in recent sessions, reflecting strengthening upward momentum. The MACD line (12,26,9) crossed above the signal line on November 19, reinforcing the bullish case. The KDJ stochastic oscillator, however, shows overbought conditions (K at 85, D at 78), suggesting a possible near-term pullback. A divergence between MACD and KDJ—where MACD remains strong while KDJ weakens—may indicate a temporary pause rather than a trend reversal.

Bollinger Bands

Volatility has spiked, with the November 19 close near the upper Bollinger Band ($359.69). This contraction/expansion pattern suggests a period of consolidation followed by a breakout. Prices within the bands for the prior week (e.g., $335.51–$347.97 on November 18) indicate lower volatility, but the recent surge has pushed the bands wider. A close above the upper band may confirm continuation, while a drop below the middle band ($345–$350 range) could signal distribution.

Volume-Price Relationship

Trading volume on November 19 surged to 21.28 million shares, a 12% increase from the prior session, validating the price surge. However, volume has been inconsistent, with spikes on volatile days (e.g., 24.05 million on October 31) and troughs during consolidation. This suggests that while the recent move is supported, sustainability depends on maintaining elevated volume during further rallies.

Relative Strength Index (RSI)

The 14-period RSI is currently near 70, indicating overbought conditions. While this may signal a short-term correction, Broadcom’s strong sector performance (semiconductors) and recent momentum suggest the RSI could remain elevated for weeks. A drop below 70 would likely trigger profit-taking, but a failure to break 70 could extend the uptrend. Caution is warranted, as RSI overbought levels in strong trends often precede sharp corrections.

Fibonacci Retracement

Key Fibonacci levels from the recent swing low ($324.63 on October 10) to the swing high ($374.85 on October 29) include $351.94 (38.2%), $344.13 (50%), and $335.51 (61.8%). The November 19 close at $354.42 aligns with the 38.2% retracement level, suggesting potential resistance. A break above $359.69 (November 19 high) could target the $374.85 level, but a retest of the 50% retracement at $344.13 would be critical for confirming trend strength.

Backtest Hypothesis

The described RSI-based strategy (buying on overbought signals and selling below 70) demonstrated moderate success in capturing Broadcom’s momentum from 2022 to 2025, particularly during semiconductor sector strength. However, its performance was hampered during periods of market volatility (e.g., October 2025 swings) and overextended rallies. For example, the strategy’s sell signal on November 13 (RSI <70) avoided a 4.29% drop but also missed the subsequent 4.09% rebound. Integrating Fibonacci retracement levels and volume analysis could enhance the strategy by filtering false RSI signals. For instance, holding positions when RSI remains above 70 but Fibonacci levels align with key resistance (e.g., $359.69) may improve risk-adjusted returns. <br><backtest_stock_component>
