OIH heads into the second week of May with a striking disconnect: the ETF has staged a 10% recovery over the past month while short sellers have rapidly unwound positions — yet the ORTEX short score holds near 67, signalling the bearish structure hasn't fully cleared.
The short interest story is the standout this week. Short interest has collapsed by nearly 38% over the past month, from around 1.35 million shares in late March to roughly 839,000 now — the lowest level in the 30-day window. The April 9–10 pivot was dramatic: short interest halved almost overnight, from above 1.28 million shares to 747,000, before edging back to current levels. That speed of unwind points less to a slow squeeze and more to deliberate position reduction, likely tied to oil price volatility following tariff-driven macro turbulence in early April. On a week-over-week basis, short interest is essentially flat — down less than 0.1% — suggesting the rapid de-risking has run its course for now.
The lending market reinforces a picture of moderate rather than extreme pressure. Availability has tightened somewhat, with the borrow pool sitting at roughly 77% utilised — well off the 100% peak seen earlier in the 52-week window. Cost to borrow ticked up about 11% on the week to just under 2%, but remains historically modest for an ETF of this type and is down 23% from a month ago. The borrow market is firm but not squeezed. That matters because at 21.2% of free float, short interest in OIH is genuinely elevated — higher than most of its underlying holdings, where even at 22% and at 13.6% are the most shorted names in the oil services space.
Options positioning has flipped noticeably less defensive than the recent trend. The put/call ratio has dropped to 0.96, more than half a standard deviation below its 20-day average of 1.06. Back in early April, when macro fear was at its highest, the PCR was running above 1.40 — near the 52-week range top of 3.47. The shift from heavy put demand to something closer to neutral is consistent with the short covering story: traders who were hedging downside exposure have stepped back. The current PCR sits just above the 52-week floor of 0.90, meaning options sentiment is now among the least bearish it has been all year.
The broader oil services backdrop shapes the context. Underlying names like SLB, HAL, and BKR all carry relatively modest short interest of 3–5% of free float, which suggests the elevated SI in OIH reflects ETF-level macro hedging rather than fundamental bets against individual operators. When macro uncertainty spiked in early April — OPEC+ supply decisions and tariff-driven demand fears both hitting simultaneously — OIH became the instrument of choice for broad energy-sector shorts. The sharp unwind since then mirrors the broader risk-on recovery across commodity-linked equities.
The ORTEX short score of 67 deserves attention precisely because it has barely moved despite the dramatic SI decline. It has drifted only from 65.9 to 67.1 over the past two weeks. A score in this range reflects a balance of factors — elevated SI as a percentage of float, still-tight borrow conditions relative to the norm, and a lending market that, while not at peak stress, hasn't fully loosened. The score suggests the crowded-short structure hasn't vanished; it has simply moderated from an extreme.
What to watch next: whether short interest re-builds from the current base, or whether the 21% float figure continues to compress — particularly if oil prices stabilise above the levels that triggered April's macro hedge wave.
