XLU, the Utilities Select Sector SPDR, has seen a dramatic reversal in short positioning this week — a meaningful shift from the bearish buildup that defined much of May and early June.
The story this week is a rapid unwinding of the short book. Short interest dropped 15% in a single week to 10.6% of the free float, with the bulk of that move coming in one session on June 9 — a 14% single-day fall. That compares starkly with the June 3 note, which flagged a 25% monthly build to 12.7% of float. The reversal has been just as fast as the buildup. Something shifted in how participants want to hold this trade.
The borrow market reflects that change clearly. Availability has loosened to 60.6% — up from just 35% the prior session and well above the near-fully-depleted readings of late May, when availability bottomed at 5.4% on May 21 and the lending pool was essentially exhausted. That extreme tightness through the final week of May made it genuinely difficult to add new short exposure. The easing since then has been dramatic, and the latest reading is the most comfortable availability has been since early May. Cost to borrow has also drifted lower, now running at 0.54%, down around 9% on the week and nearly 19% over the past month — a lending market that is becoming progressively easier to navigate for either side of the trade.
Options positioning has softened alongside the short unwind, though it remains structurally elevated for an ETF of this type. The put/call ratio is running at 2.53, fractionally below its 20-day mean of 2.64 — slightly less defensive than the recent average, a modest contrast to the heavier put demand that characterised much of May. The z-score of -1.37 puts this reading on the more constructive side of its recent range. Notably, the 52-week PCR high of 182.8 reflects a brief, extreme spike rather than a sustained positioning event, so the current level should be read against the narrower recent range, where 2.5-2.7 has been the norm. The put-heavy structure is a fixture of how XLU options are typically used — protective overlays for institutional holders — rather than a pure directional signal.
The ORTEX short score has also ticked lower, easing to 54.6 from 57.6 at the end of May. That drift confirms the broader positioning shift: the technical pressure from the short side is moderating. On the institutional side, the largest Q1 filings showed JPMorgan adding 4.5 million shares and UBS adding nearly 8.9 million — both meaningful additions into the weakness that defined early-year utilities sentiment. The stock itself is little changed on the week, up just 0.2% to $43.98, though it gained 1.1% on Tuesday.
Whether the short unwind continues or stalls — and whether the institutional buying from Q1 has been maintained into Q2 — will be worth tracking as the next round of 13F filings approaches.
