Research brief
Iron Mountain closed at $121.50 after a 3.7% weekly gain on 10.7M shares, 1.3 times its 13-week average. The weekly Trend Signal remains active for a 20th straight week, with price 12.0% above the Sharemaestro Trend Line, although four-week performance is still negative and activity pressure has cooled from recent levels.
- IRM gained 3.7% for the week, ahead of the US Real Estate sector average of -1.5% and the US Specialty REIT industry average of -0.3%.
- The Trend Signal remains active, with a 20-week active streak and price closing 12.0% above the $108.50 Trend Line.
- Volume improved to 10.7M shares, equal to 1.3x both the 13-week and 52-week averages, giving the rebound some participation but not a heavy-volume stamp.
- Risk is not absent: the stock is still 9.8% below its $134.70 52-week high, trades 36.7% above Sharemaestro Fair Value, and shows 12 recent reversal markers.
Weekly move outpaces a weak group
Iron Mountain finished the week ended 10 July at $121.50, up 3.7%, a strong relative showing in a softer Real Estate tape. The sector’s average weekly return was -1.5%, while the Specialty REIT industry slipped 0.3%. Across the broader US Real Estate peer set, IRM ranked 9th out of 249 names for the week, placing it in the 96.8th percentile.
The context matters because Specialty REIT breadth remains thin. Only 47.4% of the industry has active weekly trend signals, 42.1% shows positive Market Dynamics, and 31.6% has positive Relative Strength. IRM is one of the cleaner exceptions, with active trend, positive activity pressure and positive Relative Strength all present at the latest reading.
Trend backdrop is intact, but the short-term rhythm is uneven
The Sharemaestro setup is a balanced read, with a composite score of 63. The Trend Signal remains active and has now held for 20 consecutive weeks, while the stock has been trend-active in 33 of the past 52 weeks, or 63.5% of the window. Price closed 12.0% above the $108.50 Trend Line, keeping the weekly regime constructive despite the prior week’s sharp 11.5% drop.
Momentum is less one-sided. The latest week’s 3.7% gain and 12-week return of 3.6% are positive, and the 26-week return remains a strong 38.3%. The four-week return, however, is still -3.8%, showing that the rebound has not fully repaired the recent loss of follow-through.
Participation improves, while Market Dynamics cools
Volume rose to 10.7M shares, above the 13-week average of 7.9M and the 52-week average of 8.3M. The 1.3x volume ratio supports the idea that the bounce had broader participation than a quiet relief rally, though Sharemaestro’s watch threshold for stronger confirmation sits higher, with 1.5x volume the next more decisive marker.
Market Dynamics remain positive at 0.79, but the pressure reading is down 31.2% over four weeks. Relative Strength is also positive at 7.73, yet it has fallen 47.7% over the same span. That combination argues for a still-constructive weekly structure, but with less urgency than the late-June high-range push.
Valuation distance and reversal markers keep risk in view
IRM trades high in its 52-week range at 77.3%, but the stock is still 9.8% below its $134.70 high. The larger valuation tension is the 36.7% premium to Sharemaestro Fair Value of $88.91, which signals strong market demand but also leaves less room for disappointment if momentum fades.
Risk measures are balanced rather than benign. Thirteen-week weekly volatility is 5.1%, above the 52-week base of 4.7%. Over the past year, IRM has logged 30 positive weeks versus 22 negative weeks, with average gains of 3.6% and average losses of -3.5%. The main watch items are whether the Trend Line continues to act as the weekly regime level, whether activity pressure stabilises after its four-week cooling, and whether any next move attracts volume above the current 1.3x participation rate.
