Delta Air Lines Jumps 5.14% On Bullish Technical Reversal Signals

Delta Air Lines (DAL) rallied 5.14% in the latest session, closing at $49.46 on above-average volume of 10.2 million shares. This sharp upward move followed a three-day decline, warranting technical assessment using multiple frameworks.
Candlestick Theory
The June 16 session formed a robust bullish engulfing candle that fully consumed the prior two down days (June 12–13), signaling strong reversal momentum. The long body and minimal upper wick indicate sustained buying pressure near the close. Key resistance now emerges at $50.50 (June 10–11 highs), while support holds at $47.00 (June 13 low). The $49.60 high also aligns with the March 2025 swing point, creating a technical inflection zone.
Moving Average Theory
The 50-day moving average (~$47.20) crossed above the 100-day MA (~$46.80) in late May, confirming a bullish near-term structure. The current price trades above both averages, reinforcing positive momentum. Longer-term, the absence of 200-day MA data (due to limited history) restricts full trend evaluation, but the alignment of shorter averages suggests upside bias persists barring a close below $47.20 support.
MACD & KDJ Indicators
MACD histogram turned positive on June 16, reflecting accelerating bullish momentum as the signal line crossed upward. Concurrently, KDJ’s %K line (28 to 54) and %D line (35 to 44) executed bullish crosses from oversold territory. This dual oscillator agreement supports the candlestick reversal pattern, though KDJ’s J-line (87) nears overbought thresholds, warranting vigilance for near-term consolidation.
Bollinger Bands
Volatility expanded sharply during the June 16 rally as price breached the upper Bollinger Band (~$49.25) while bands widened. This deviation typically signals strong directional conviction but heightens mean-reversion risk. Sustainability depends on whether price maintains above the 20-day SMA (~$47.60), now acting as dynamic support.
Volume-Price Relationship
The breakout candle was validated by volume 21% above the 20-day average, confirming buyer conviction. Notably, volume during the June 16 advance exceeded volumes during the June 11–13 decline, suggesting accumulation. However, volume momentum divergence appeared in early June—higher volume on down days than up days—which the recent surge partially resolved.
Relative Strength Index (RSI)
RSI (14-day) rebounded sharply from 37 (near-oversold) to 59 after the rally, exiting cautionary territory without reaching overbought (>70) conditions. This midpoint positioning indicates room for further upside, though proximity to the 60–65 resistance zone (where pullbacks originated in May and June) suggests potential friction.
Fibonacci Retracement
Applying Fib levels to the primary downtrend from the January 2025 high ($69.98) to April 2025 low ($35.13): the 38.2% level ($48.44) provided support during the June 13 selloff ($45.86 low). The current price sits between the 38.2% and 50% ($52.56) retracements. A sustained break above $48.44 opens the path toward the 50% level ($52.56), closely aligning with June’s $52.00–$52.08 resistance zone. The 61.8% level ($56.66) remains the next major upside target.
Confluence exists between Fibonacci support ($48.44), the 50-day MA ($47.20), and Bollinger’s midline ($47.60)—a zone that reinforced the June 16 reversal. Divergence occurred in early June when price hit higher highs while RSI and volume momentum weakened, subsequently triggering a 13% correction. Current technical alignment favors bullish continuity if $48.44 support holds, though overextension risks highlighted by Bollinger Band penetration and near-overbought KDJ warrant monitoring for consolidation.
