Iron Mountain Stock Surges 4.59% to $96.67 on Bullish Technical Momentum

Iron Mountain Technical Analysis
Candlestick Theory
Iron Mountain displays a robust bullish momentum as evidenced by five consecutive white candlesticks culminating in a 4.59% surge to $96.67 on September 9, 2025. This pattern suggests strong buying pressure, though the elongated upper wick ($96.80 high vs. $96.67 close) hints at temporary profit-taking near the psychological $100 resistance. Key support emerges at $89.46–$90.04 (August–September consolidation floor), while resistance crystallizes at the $97–$100 zone, where prior rallies stalled in May and July.
Moving Average Theory
The stock trades decisively above all critical moving averages: 50-day ($93.20), 100-day ($95.10), and 200-day ($93.80), confirming a long-term uptrend. The 50-day MA recently crossed above the 200-day MA (Golden Cross in mid-August), reinforcing bullish sentiment. Sustained price action above the converging MAs signals robust trend strength, though a close below the 50-day MA would warrant caution.
MACD & KDJ Indicators
MACD (12,26,9) shows a widening positive histogram above the signal line, confirming accelerating upward momentum. KDJ oscillators (K:78, D:72, J:90) reside in overbought territory but maintain bullish alignment without divergence. While this suggests near-term exhaustion risks, the absence of bearish crossovers implies momentum could extend before a pullback.
Bollinger Bands
Price consistently tests the upper Bollinger Band ($97.20, 20-day SMA, 2σ), reflecting strong directional bias. Band expansion since early September aligns with volatility surge during the breakout. The absence of price contraction suggests limited consolidation probability near-term. A retreat toward the midline ($94.50) would offer a potential pullback entry.
Volume-Price Relationship
Recent rally days (September 3–9) saw volume surge 20–50% above the 30-day average, validating breakout authenticity. Notable accumulation occurred at $90–$92 support (2.4M shares vs. average 1.6M), establishing a high-volume node. Declining volume on minor retracements (e.g., September 8 dip) underscores limited selling conviction.
Relative Strength Index (RSI)
The 14-day RSI reads 73, crossing into overbought territory. While this warns of potential consolidation, its trajectory remains ascending without bearish divergence. Historically, Iron Mountain tolerates prolonged RSI readings above 70 during strong trends (evident in Q1 2025 rally), suggesting overbought conditions may persist before material correction.
Fibonacci Retracement
Using the March 2025 trough ($80.47) and July 2025 peak ($103.25), key Fib levels emerge. The recent breakout cleared the 50% retracement ($91.86), turning it into support. The 61.8% level ($94.70) now acts as dynamic reinforcement. Critical resistance aligns with the 78.6% retracement at $98.20 and the psychological $100 threshold—a confluence of technical and emotional barriers.
Confluence & Divergence
Significant confluence exists at $94.50–$95.00, where the 50-day MA, Bollinger midline, and Fib 61.8% level converge. This zone offers robust dynamic support. No material inter-indicator divergences are observed, though RSI overbought signals against sustained volume-backed rallies warrant monitoring for exhaustion signs. Overall, multiple indicators align in confirming the bullish structure, with $98–$100 as the next decisive resistance test.
