GDX is caught in a striking contradiction: short sellers have been retreating rapidly even as the ETF pulls back sharply from its recent highs, leaving the positioning story more nuanced than a 3% single-day drop suggests.
The most telling development this month is the scale of the short cover. Short interest has fallen nearly 17.5% over the past 30 days, dropping from roughly 45.8 million shares to 37.8 million — now 12.5% of the free float. The bulk of that move happened in a single week around August 10-11, when short interest shed more than 5 million shares in just a few sessions. That's not a gentle unwind; it looks like a forced cover coinciding with GDX's extraordinary 24.7% one-month rally to $88.95. Bears who were short into gold's run got squeezed, and the positions reflect it.
The lending market backs up that read, but with a fresh twist. Availability has tightened materially this week. It dropped from 130% last Friday to roughly 89% today — meaning shares available to borrow are now worth only about 89 cents for every dollar currently lent out. That's a notable tightening from the looser conditions of late July, when availability was running above 150-175%. Cost to borrow, however, is moving the other way: it fell 44% over the week to just 0.39%, a 30-day low. The divergence is interesting — the borrow pool is shrinking, but lenders aren't yet repricing the risk. That combination suggests the squeeze of the past month has cleared out most of the weak short positions, with the remaining shorts holding at low cost.
Options traders are incrementally more defensive than usual. The put/call ratio has climbed to 1.44, about 1.3 standard deviations above its 20-day average of 1.33, and the ratio has drifted higher in each of the past four sessions. That's not extreme by the 52-week range — the high is 2.06, the low 0.91 — but the directional drift toward more put protection since August 11 is worth noting. It follows a single-day drop of 3.2% on August 18, the sharpest daily move in this recent stretch, suggesting some holders are reaching for downside cover after a monster run.
The ORTEX short score sits at 65.5, roughly stable over the past two weeks after drifting slightly lower from 66.8 on August 6. That level still reflects a moderately elevated bearish signal — not extreme, but not neutral either. The score has compressed as short interest fell, consistent with bears having reduced their conviction rather than rebuilt it.
On the institutional side, BMO Asset Management is the dominant holder at 5.8% of shares, and added 1.76 million shares in the quarter ending June 30. Citigroup added 1.35 million shares in the same period. The notable outflow came from JPMorgan, which cut its position by nearly 2.9 million shares — a meaningful trim from one of the larger trading desks. That divergence between Canadian and US banking book activity is worth tracking as gold continues to set the tone for the miners.
The setup heading into next week: GDX has retraced roughly 1.3% over seven days after a historic one-month run, borrow availability is tightening even as cost to borrow eases, and options hedging is picking up at the margin. The key variable to watch is whether gold's underlying bid holds — because if the metal stalls, the remaining 12.5% short interest and a tighter lending pool create the conditions for a more contested tape.
