Paccar Shares Rise 4.34% on Bullish Breakout and Key Resistance Clearing

Paccar (PCAR) has experienced a 3.14% gain in the most recent session, marking two consecutive days of positive momentum with a cumulative 4.34% rise. This price action reflects a potential short-term bullish continuation, supported by a recent consolidation phase followed by a breakout above key resistance levels. The candlestick pattern suggests a possible "Bullish Engulfing" formation at the recent lows, indicating a reversal from bearish to bullish sentiment. Key support levels appear to be forming around the $97–$98 range, while resistance is evident at $100–$102. The 50-day moving average currently resides at approximately $99.50, above the 200-day average of $97.50, reinforcing a medium-term bullish trend. A crossover of the 50-day above the 200-day line earlier in the year has provided a structural bias for upward momentum, though recent volatility may test the 100-day average ($98.50) as a potential trigger for near-term corrections.

The MACD histogram has shown a narrowing of bearish divergence over the past week, with the fast line crossing above the signal line in early September, suggesting a shift in momentum. The KDJ stochastic oscillator currently indicates overbought conditions, with %K at 85 and %D at 80, signaling potential exhaustion in the recent rally. This confluence of overbought momentum indicators and a narrowing MACD histogram may foreshadow a retracement toward the $98.50–$99.50 range. Bollinger Bands have expanded significantly in recent sessions, with the price trading near the upper band, reflecting heightened volatility. A contraction in band width earlier in August preceded the recent breakout, suggesting that the current expansion may persist unless a key support level like $97.50 is breached.

Volume has surged during the recent two-day rally, with trading volumes exceeding 2.6 million shares on the breakout day, validating the strength of the upward move. However, divergences emerge when comparing volume to price action: while volume spiked on the breakout, it did not reach levels seen during the March–April rally, raising questions about the sustainability of the current momentum. The RSI stands at 60, below the overbought threshold, but its upward slope suggests potential for a push toward 70. A break above 70 would trigger caution, though the indicator’s current position still aligns with the broader bullish trend. Fibonacci retracement levels derived from the March–July decline highlight critical support at 38.2% ($98.50) and 61.8% ($99.50), both of which align with moving average confluence points. A failure to hold these levels could invalidate the bullish case.

Backtest Hypothesis

A backtesting strategy could leverage the confluence of overbought KDJ readings and a bullish MACD crossover to trigger long entries. For instance, a long signal could be generated when the 50-day MA crosses above the 200-day MA (a "Golden Cross") and the RSI remains above 50 for three consecutive days. A stop-loss could be placed below the 200-day MA, with a target aligned with the 61.8% Fibonacci level. Historical data from August 2025 shows such a strategy would have captured the recent rally, though it would have been challenged during the March–April volatility. Integrating volume divergence as a filter—requiring a 15% increase in volume on the breakout day—could enhance risk-adjusted returns by avoiding false breakouts.
