UNG enters the back half of September with short sellers in full retreat — a notable shift for a fund that spent most of August under meaningful bearish pressure.
The scale of the short exit is the week's defining story. Short interest has fallen 43% over the past week alone, dropping from roughly 4.2 million shares to just under 2.4 million. That brings SI down to 4.9% of free float — still above the threshold where it matters, but less than half the peak levels seen in early August when shorts held above 6.7 million shares. The one-month decline is even starker at 46%. This is not a gradual unwind; it looks like a rapid cover driven by the fund's improving price action.
The borrow market tells the same story from a different angle. Availability has loosened dramatically — from a 52-week low of just 2.4% (close to fully consumed) earlier in the year to 571% today, meaning there are now nearly six shares available for every one currently borrowed. That's a market that has gone from tight-to-squeezed to genuinely comfortable in a matter of weeks. Cost to borrow has followed availability higher, easing 47% over the past month to just 0.67% annually — firmly in the "easy borrow" range where there's no friction for would-be shorts. Options traders are equally relaxed: the put/call ratio of 0.33 is fractionally below its 20-day average of 0.34, with a z-score near zero. No defensive hedging signal here.
The price recovery underpins the whole picture. UNG closed at $10.54 on September 15, up 2% on the day and 6.3% over the past month. The ORTEX short score has dropped sharply in tandem — from 60.6 a week ago to 42.5 today — reflecting the combined move of falling short interest, looser availability, and a rising price. A score in the low 40s is broadly neutral, suggesting the fund no longer carries the short-side pressure that defined much of the summer.
One data point worth noting: the ORTEX short score hit its recent high of 60.6 on September 7, the same week that short interest peaked above 4.1 million shares and availability was running below 100%. The subsequent week saw both reverse simultaneously — availability tripling from around 125% to 570%, and short interest nearly halving. That kind of simultaneous cover-and-loosen pattern typically reflects short sellers exiting rather than rotating.
Institutional ownership is thin and largely made up of market makers and broker-dealers — Goldman Sachs holds the largest reported stake at just 2.1% — consistent with UNG's nature as a commodity ETF used for tactical positioning rather than long-term holdings. No analyst coverage or activist presence applies here.
The next read worth watching is whether natural gas spot prices sustain the move that has driven this cover, or whether the shorts who exited find reason to rebuild as the winter demand narrative develops through October.
