IRM Options Caution Persists as November Print Looms

Iron Mountain enters its November 5 earnings date with options traders holding a more defensive position than they have for most of the past year, even as the stock has added 6% over the past week to close at $116.55.

The put/call ratio is running at 1.80, above its 20-day average of 1.51 and more than one standard deviation above that mean. That is a shift in tone from the note published October 28, which observed the ratio stabilising after a sharp run-up. It has since edged back toward the elevated territory seen in late October, when it reached 1.90. The 52-week peak is 2.42, so the reading is not at an extreme, but it has stayed persistently above its recent average for two weeks now, a longer run of defensive positioning than any comparable period in the data. Close peers moved in a similar direction on the week: EQIX gained 6.1% and DLR rose 4.8%, so Iron Mountain's recovery is broadly in line with the data-center REIT group rather than a company-specific repricing.

The borrow market has nothing bearish to add. Short interest has fallen roughly 5% on the week to 2.4% of free float, continuing a gradual decline from early October levels near 2.7%. Availability is extremely loose at 6,793%, meaning the pool of shares available to borrow dwarfs what is currently lent out. Cost to borrow has dropped 24% over the week to 0.39%, a low by any measure. Nothing in the lending market suggests organised short-side pressure heading into the release.

Analyst sentiment is broadly constructive, though the most recent changes are from September. Barclays maintained its Overweight rating and raised its target to $144 on September 8. Rothschild initiated with a Buy and a $132 target on September 21. Truist lifted its target to $155 in late August. The consensus mean price target of $144 implies roughly 24% upside from the current price, a gap that has been a persistent feature of this stock all year. EPS momentum factor scores rank in the 68th and 80th percentiles on the 30-day and 90-day windows respectively, suggesting estimate revisions have been moving in a positive direction. Against that, the earnings yield ranks only in the 22nd percentile, and the EV/EBIT factor score sits at the 18th, reflecting the premium valuation the market already assigns to Iron Mountain's data center growth story.

The print will therefore test whether management can sustain the revenue trajectory that has justified a 43x price-to-earnings multiple and a year-to-date gain of roughly 38%, at a time when options traders have quietly been buying more protection than usual.
