XME, the SPDR S&P Metals & Mining ETF, faces a sharp divergence this week: shorts have retreated aggressively while the borrow market remains nearly locked shut — a combination that tells two very different stories about how the market is reading the metals complex right now.
The most striking development in short positioning is the pace of covering. Short interest has dropped 25% over the past week, falling from roughly 6.3 million shares to around 4.7 million — now representing 17.2% of float. That is still a high absolute level, but the direction of travel has reversed hard. Looking back further, shorts peaked near 6.9 million shares in early August and have been steadily retreating ever since, closely tracking the ETF's 17% price gain over the past month. XME closed at $118.74 on Thursday, with the one-month rally doing real damage to bearish theses. Friday alone saw a 3.5% pullback, which may cool some of the covering momentum heading into next week.
The borrow market, however, tells a more cautious story. Despite shorts running for the exits, availability has barely moved — it remains deeply constrained at just 9.4%, meaning only about one share is available for every ten already borrowed. That reading has been almost uniformly in single digits for most of August; the 52-week trough hit 1.1%. Cost to borrow ticked up about 6% on the week to 1.41%, modest in absolute terms but reflecting a lending pool under sustained pressure. The paradox is notable: shorts are covering, yet the supply of loanable shares is not loosening. That suggests the covering is being absorbed without freeing up meaningful inventory, keeping the structural short squeeze potential alive even as the headline SI figure falls.
Options positioning has shifted alongside the broader sentiment improvement. The put/call ratio has eased to 0.84, slightly below its 20-day average of 0.85 and near the lower end of recent readings — though still well off the year's low of 0.75 set in mid-August. The z-score of -0.21 signals a mild lean toward calls, consistent with the rally environment but not aggressively bullish. For context, the PCR touched above 1.0 through late July and into early August when shorts were at their heaviest; the drift lower tracks the price and SI improvement almost exactly. Overall, positioning has rotated from defensive to neutral-constructive over the past six weeks, though it has not tipped into outright complacency.
Institutional flows add another layer of texture. Managed Account Advisors held around 18% of shares as of end-June, having added roughly 377,000 shares in the quarter — the largest holder by a wide margin. Meanwhile, Morgan Stanley trimmed nearly 425,000 shares and Bank of America cut about 166,000 over the same period. The net institutional picture from Q2 is thus one of concentration: a few large holders building while some of the more liquid, broker-affiliated accounts reduced exposure. La Caisse de dépôt et placement du Québec initiated a fresh position of 615,000 shares, suggesting international institutional interest in the metals space was picking up even before the summer rally gathered pace.
The ORTEX short score has been easing in tandem with the covering trend, dropping from 70.6 on August 17 to 66.6 now — moving in the right direction for longs, though it remains firmly in elevated territory. The score is consistent with a market that has reduced its most aggressive short positions but has not yet declared the bearish thesis dead. With the ETF down 3.5% on its last session, the week closes on an ambiguous note: whether Friday's pullback is a normal pause after a powerful month, or whether it marks renewed short interest building into a resetting tape, is what defines the setup heading into September.
