Iron Mountain Surges 4.58% to $104.72 as Technical Indicators Signal Bullish Momentum

Candlestick Theory
Iron Mountain’s recent price action exhibits bullish momentum, with a 4.58% surge on September 22, 2025, forming a robust bullish candle that closed near its high of $104.72. This follows a hammer-like candle on September 19 (low: $98.49, close: $99.89), signaling rejection of lower prices. Key resistance is evident near $105–$106, aligning with the yearly high from June 24, 2025 ($105.57). Support emerges around $98.50–$99.00, reinforced by the September 19 low and psychological support at $100. A bearish engulfing pattern on August 6 (–5.77%) highlighted prior resistance, now converted to support near $90–$92.
Moving Average Theory
The 50-day, 100-day, and 200-day moving averages (MAs) reflect a bullish trend structure. Current price ($104.46) trades above all three MAs, with the 50-day MA (∼$98) recently crossing above the 100-day MA (∼$95), confirming a bullish "golden cross" in late August. The ascending order—50-day > 100-day > 200-day (∼$92)—signals sustained upward momentum. Near-term pullbacks are likely to find dynamic support at the rising 50-day MA, while a decisive break below $98.50 could signal trend weakness.
MACD & KDJ Indicators
The MACD histogram shows bullish acceleration, with the signal line crossing above the MACD line in early September. This aligns with the price rebound from $96.69 (September 12) to $104.46. KDJ metrics indicate overbought territory (K and D > 80), typical of strong trends but warranting caution for a short-term pullback. No bearish divergence exists; both oscillators support the uptrend. The KDJ "golden cross" on September 15 preceded the current rally, reinforcing bullish momentum.
Bollinger Bands
Bollinger Band width contracted sharply in mid-September (volatility squeeze), culminating in the September 22 breakout above the upper band ($103). This expansion signals renewed bullish momentum. Price now trades near the upper band, suggesting short-term overextension but validating strength. The breakout target aligns with the yearly high ($105.57). Support rests at the 20-day moving average (mid-band, ∼$100), with a close below potentially indicating consolidation.
Volume-Price Relationship
Recent gains are validated by supportive volume. The 4.58% rally on September 22 occurred on above-average volume (2.14M shares vs. 30-day avg. ∼1.8M), confirming buyer conviction. Notably, the September 19 advance (+0.98%) saw elevated volume (3.12M), hinting at accumulation. However, the August 6 sell-off (–5.77%) spiked volume (4.97M), underscoring capitulation. Current volume patterns lack bearish divergence, sustaining the uptrend’s credibility.
Relative Strength Index (RSI)
The 14-day RSI (∼65) approaches overbought territory but remains below the 70 threshold, suggesting room for further upside. RSI bottomed near 40 in early September (oversold warning), coinciding with the $96.69 low before a sharp rebound. While not yet overbought, the rapid RSI ascent may precede short-term consolidation. No bearish divergence is evident, as higher price highs align with rising RSI.
Fibonacci Retracement
Applying Fibonacci to the March 2025 low ($72.33) and current recovery swing:
- Key levels: 78.6% retracement ($102.01), 100% extension ($110.09).
The stock recently surpassed the 78.6% level, closing at $104.46, indicating bullish strength targeting $110. The September pullback to $96.69 respected the 61.8% retracement ($95.67), reinforcing this level as major support. Confluence exists at $105–$106 (yearly high + 88.6% Fib), making it critical resistance.
Confluence and Conclusion
Multiple indicators converge to support Iron Mountain’s bullish posture:
- Confluence: Moving averages, MACD, and volume confirm the breakout above Fibonacci resistance ($102.01). The Bollinger Band expansion and KDJ momentum align with targets toward $105–$106 and ultimately $110.
- Divergences/Caveats: RSI and KDJ overbought signals suggest near-term consolidation risk, but no indicator shows bearish divergence. A close below $98.50 (support cluster) would invalidate the bullish structure.
Overall, technicals favor continued upside, with pullbacks to $99–$100 offering probabilistic entry opportunities.
