Shorts pile into BOE: +2.03% in a week to 22.98% shorted
Week 43, 2025 (20 Oct 2025 — 24 Oct 2025)
Boss Energy (BOE) is now the most shorted stock on the ASX at 22.98%, after a sharp +2.03% WoW jump — the standout move in an otherwise flat week (period average change: -0.01%). Lithium shorts eased (PLS -1.40%, MIN -0.84%), while PWR (PWH) copped fresh selling (+1.43%) and Qualitas (QAL) saw shorts vanish (2.09% → 0.01%).
This Week's Analysis
The week’s message from short sellers was clear: they’re leaning hard into uranium execution risk. BOE’s short interest jumped from 20.96% to 22.98% (+2.03%) — a big weekly move by any standard — and it now sits as the most shorted name in the dataset. When a stock is already heavily shorted and still attracts another two percentage points in a week, that’s not casual trading; it’s a conviction bet that something in the near-term story doesn’t line up with the share price.
BOE (22.98%, +2.03%) is the headline. The company is in ramp-up mode at Honeymoon and progressing Alta Mesa, which is exactly when shorts like to press: commissioning, throughput, recoveries, and timelines are where optimism meets reality. If you want to understand the bull case management is selling, start with BOE’s quarterly materials and investor deck (http://www.bossenergy.com/images/media/2973720.pdf and http://www.bossenergy.com/images/documents/Dec24-Quarterly-Results-Presentation.pdf). The short thesis is most likely that the market is pricing a smooth ramp and supportive uranium pricing, while the risk list (price swings, regulation, operational execution) is where the surprises usually live. PLS (16.05%, -1.40%) is still heavily shorted, but the pressure eased meaningfully this week. That looks like position trimming rather than a full change of mind — 16% short is still a crowded trade — but it does suggest some shorts are taking profit or reducing exposure into the next catalyst window. PLS remains the liquid way to express a lithium price view, and its own quarterly advisory is the kind of document shorts will comb for unit costs, realised pricing and demand tone (https://1pls.irmau.com/site/pdf/3bba2523-52c7-4c38-bc03-b945945d9698/December-2025-quarterly-activities-report-advisory.pdf?Platform=ListPage). DMP (14.54%, -0.09%) and GYG (12.64%, -0.09%) were basically unchanged. That reads as “hold the line” positioning: both sit in consumer-facing categories where any wobble in spending, wage costs, or discounting can bite margins, but there was no fresh aggression from shorts this week. PDN (12.16%, +0.41%) ticked higher, reinforcing that uranium isn’t a one-stock story. PDN’s annual report is a useful reference point for how the company frames its asset base and risks (https://www.paladinenergy.com.au/wp-content/uploads/2025/10/Paladin-2025AnnualReport-Full-Web.pdf).

Movers Analysis
Beyond BOE, the other eye-catcher was PWH: short interest rose from 10.21% to 11.64% (+1.43%). That’s a sizeable weekly jump for an industrial/motorsport supplier, and it smells like earnings positioning. PWH is exposed to global manufacturing cycles and customer program timing; when shorts add this quickly, they’re usually betting that growth expectations (or margins) are too rosy, or that the market is paying up for a quality story right as conditions tighten. MMS moved from 1.71% to 3.07% (+1.36%). Salary packaging and vehicle finance can look defensive, but it’s also a sector where regulation and funding conditions matter. A jump from low levels often signals a new thesis forming rather than a crowded trade. BRN climbed from 4.58% to 5.89% (+1.31%). For a speculative tech name, shorts tend to show up when commercial traction lags the narrative. The provided BRN documents are product guides rather than financial updates (e.g., https://brainchip.com/wp-content/uploads/2024/11/Akida-Edge-AI-Box-Model-Deployment-Guide.pdf), but the market debate is the same: real revenue adoption versus perpetual “next partnership”. On the cover side, QAL was extreme: 2.09% → 0.01% (-2.09%). That’s not a gentle unwind — it’s basically an exit. Without a specific news item in this dataset, the cleanest read is shorts closing because the borrow got tight, the risk/reward flipped, or a corporate action/positioning event made staying short unattractive. PLS (-1.40%), ILU (-0.86%), and MIN (-0.84%) all de-shorted together, which looks like a resources risk-on pulse or profit-taking after a strong run in the “short resources” trade. MIN’s FY25 results pack is the anchor document for anyone debating balance sheet and commodity sensitivity (https://cdn.sanity.io/files/o6ep64o3/production/b23c9b1f93dbe5cc41520061cafecf0c1d214c77.pdf).
Industry Trends
Two sector threads ran in parallel. First, uranium shorts got louder: BOE surged (+2.03%) and PDN edged up (+0.41%). That’s consistent with a view that uranium equities have run ahead of operational reality — especially for names in ramp-up or integration mode — and that any hiccup in production, costs, or timing can hit hard when expectations are high. Second, lithium shorts eased across the big liquid names (PLS down 1.40%, MIN down 0.84%). That doesn’t mean the lithium bear case is dead; it means the trade may be less one-way right now. When multiple lithium-linked shorts are reduced in the same week, it often reflects either a stabilisation in the commodity tape, or simply that the easy money on the downside has been made and traders are resetting risk. Outside resources, the consumer complex remains heavily shorted but stable (DMP, GYG, FLT). That’s a sign shorts are waiting for the next datapoint — trading updates, cost inflation signals, or any shift in rate expectations that changes discretionary spending maths.
Outlook
Next week, watch for any uranium price volatility and company updates that speak to ramp-up execution — BOE and PDN are where the positioning is most aggressive. On the macro side, any shift in rate expectations will matter for the consumer shorts (DMP, GYG, FLT) and for valuation-sensitive growth names like PWH and BRN.
