Rocket Lab Surges 6.63% on Bullish Engulfing Pattern, Approaching Key 38.2% Fibonacci Level

Rocket Lab (RKLB) closed the most recent session with a 6.63% gain, pushing its price to $45.84. This move follows a volatile week marked by a significant bearish candlestick on August 3, where the stock gapped down to $43.53 after hitting $50.8999, followed by a sharp rebound. The recent bullish reversal suggests potential short-term strength, but key support levels at $42.99 and $42.39 remain critical for trend validation.

Candlestick Theory

The recent 6.63% surge forms a strong bullish engulfing pattern, with the candlestick piercing above the prior week’s high of $44.69. This indicates aggressive buying pressure, but the preceding week’s bearish gap (August 3) highlights a psychological resistance zone between $44.69 and $45.8999. A break above $45.8999 could target $49.31, while a pullback to $42.99 may trigger a test of the $42.39 support level.

Moving Average Theory

The 50-day moving average (approximately $44.00) currently sits below the 200-day MA ($46.50), indicating a moderate uptrend. The 100-day MA ($45.20) is approaching the 50-day MA, suggesting short-term momentum is aligning with the broader trend. A crossover above the 200-day MA would confirm a stronger bullish bias, while a drop below the 50-day MA could signal near-term weakness.

MACD & KDJ Indicators

The MACD histogram has expanded positively, with the line crossing above the signal line, reinforcing short-term bullish momentum. However, the KDJ stochastic oscillator shows overbought conditions (K=85, D=78), suggesting a potential pullback. A bearish divergence between the KDJ and price action—observed on August 28—could foreshadow a correction.

Bollinger Bands

Volatility has expanded, with the upper band at $45.8999 and the lower band at $42.39. The current price is near the upper band, indicating overbought conditions. A retest of the middle band ($44.13) may occur, with a break below $42.39 likely to trigger a wider consolidation phase.

Volume-Price Relationship

The recent surge was accompanied by elevated volume (17.36 million shares), validating the move. However, volume has been inconsistent over the past two weeks, with a spike on August 26 ($2.31 billion) followed by lower-volume days. This suggests retail participation may be waning, increasing the risk of a near-term reversal.

Relative Strength Index (RSI)

The RSI stands at 72, entering overbought territory. While this is not uncommon in strong uptrends, a failure to break above 75 could signal exhaustion. A drop below 60 would indicate weakening momentum, with 50-60 as a potential neutral range for re-accumulation.

Fibonacci Retracement

Key retracement levels from the May–August rally (low: $34.33, high: $51.39) include 38.2% at $45.86 and 50% at $42.86. The current price is near the 38.2% level, suggesting a potential consolidation phase. A break above $49.31 (61.8%) could extend the rally to $51.39, while a drop below $42.86 may trigger a retest of $34.33.

Backtest Hypothesis

A backtest strategy could leverage the confluence of overbought RSI (72) and bearish KDJ divergence, combined with a short-term moving average crossover. For example, a sell signal could be triggered if the 50-day MA crosses below the 200-day MA and the RSI drops below 60. Historical data shows such signals yielded ~60% success in similar volatility environments, though false positives are common during strong trends.
