Jabil Jumps 2.83% to $180.82 as Technicals Signal Bullish Continuation

Jabil (JBL) rose 2.83% to close at $180.82 on June 16, 2025, reversing the previous session's decline as its highest single-day gain in two weeks. This price action warrants a detailed technical assessment through multiple lenses.
Candlestick Theory
The June 16 bullish candle closed near its high ($182.14) following a bearish session on June 13 ($175.08 low), suggesting absorption of selling pressure. This pattern resembles a bullish engulfing structure, confirming $175 as critical support. Resistance is now evident near $182–$182.50, aligning with June's swing high. A sustained close above $182.50 may trigger further upside, while failure risks retesting $175 support.
Moving Average Theory
The stock trades decisively above its 50-day ($170 approximated), 100-day ($155), and 200-day ($140) moving averages—indicating robust bullish alignment across timeframes. The 50-day remains above the 100-day and 200-day, reinforcing the primary uptrend. Current price positioning shows no imminent threat to the established trajectory, though overextension risks warrant monitoring near-term mean reversion.
MACD & KDJ Indicators
MACD registers a bullish crossover with histogram bars expanding, supporting momentum continuation. Conversely, KDJ’s %K (87) reflects overbought conditions after rapid ascent from sub-50 levels in early June. While MACD’s positive divergence underscores trend strength, KDJ’s overbought reading signals potential consolidation. This divergence between medium-term momentum (bullish) and short-term stochastic (overextended) highlights rotational risk.
Bollinger Bands
Price touches the upper Bollinger Band ($182), typically a resistance zone during normal volatility regimes. Bandwidth expansion from June’s lows confirms increasing volatility, though the absence of pronounced contraction limits predictive utility. A rejection at the upper band would favor retracement toward the 20-period SMA near $170, while decisive breakout may accelerate upside.
Volume-Price Relationship
Volume surged 85% to 2.27 million shares on June 16’s rally, validating bullish conviction. This contrasts with distribution patterns during June’s minor pullbacks (e.g., June 13 volume dropped 45% vs. June 10). Sustained volume support on advances reinforces underlying strength, though deteriorating volume on subsequent highs would challenge continuation.
Relative Strength Index (RSI)
Using RSI = [Average Gain / (Average Gain + Average Loss)] × 100 over 14 days, the calculated RSI is approximately 75.1—exceeding the 70 overbought threshold. While this warns of exhausted upside momentum, such levels can persist in strong trends. Its validity as a reversal signal requires confirmation from other indicators given the stock’s powerful uptrend.
Fibonacci Retracement
From the April 22 low ($130.75) to June 16 high ($182.14), key retracement levels emerge: 23.6% ($170.00) and 38.2% ($162.50). Current price sits near the 0% extension, with $170 serving as immediate Fibonacci support. Confluence exists at $170, where the 23.6% retracement, 50-day MA, and psychological level intersect—strengthening its technical significance.
Synthesis reveals a predominantly bullish structure with moving average alignment, volume-backed breakouts, and MACD momentum. However, RSI and KDJ overbought conditions, coupled with resistance at the Bollinger Band and $182.50, advise caution. The $170 confluence zone (Fibonacci/MA) offers critical support for trend preservation. A decisive breach above $182.50 could unlock $185–$190 targets, whereas failure risks consolidating near recent highs.
