This Week's Analysis
PLS just delivered the kind of weekly short move that makes you sit up: 6.50% to 11.53% (+5.03%). That’s not “tweaking exposure” — that’s a crowd trade, and it dragged lithium back into the centre of the short conversation on the ASX.1
At the top, LOT remains the market’s favourite short at 19.54% after another lift from 18.33% (+1.20%).2 DMP (15.20%, -0.07%) and TLX (15.15%, +0.17%) are basically steady, suggesting conviction is already high and the marginal changes are small.1 BOE sits at 14.33% (+0.15%), keeping uranium well represented alongside LOT.1 On the consumer side, shorts eased in TWE (13.07%, -0.51%), GYG (12.66%, -0.34%), CAR (11.24%, -0.28%) and FLT (10.77%, -0.52%).1 That’s a subtle “less aggressive” tone in discretionary and travel, even while the overall market average short position ticked up +0.02% WoW to 1.53% across 688 stocks.1

Movers Analysis
PLS is the headline: a +5.03% jump in short interest in one week is extreme by ASX standards.1 The fundamental backdrop gives shorts a clean narrative: FY25 revenue declined 39% to $769M and the company posted a statutory loss after tax of $196M (with an underlying loss after tax of $88M), even as cash margin from operations was $192M.3 In other words, cash generation exists, but earnings are ugly — and shorts are leaning into that. On the other side, PNV saw a sharp unwind: 11.63% to 8.02% (-3.61%).1 That’s consistent with a business that printed FY25 net profit after tax of $13.2M and total revenue of $129.2M (with NovoSorb group sales of $118.6M).4 ARU also saw a big de-risking move (6.06% to 2.89%, -3.17%), and BAP eased from 10.94% to 9.41% (-1.53%).1 Meanwhile, shorts also lifted in ASX (2.29% to 3.24%, +0.94%) and 4DX (9.14% to 10.06%, +0.92%), the latter a classic high-beta setup with a beta of 2.01.15
Industry Trends
Two sector stories jump out. First, resources is where the aggression is: LOT (19.54%, +1.20%) and BOE (14.33%, +0.15%) keep uranium crowded, while PLS (+5.03% to 11.53%) shows shorts are happy to press lithium when the numbers look weak.13 Second, the consumer complex looks like it’s getting a small reprieve: TWE (-0.51%), GYG (-0.34%), FLT (-0.52%) and CAR (-0.28%) all saw shorts trim rather than add.1
Outlook
Watch whether PLS short interest keeps climbing from 11.53% — after a +5.03% week, the next move tends to be either a continuation or a violent reversal.1 Also keep an eye on whether LOT can hold below 19.54% short if uranium sentiment turns, because it’s already the market’s max short position this week.1
