The 10 Most Shorted ASX Stocks · Week 22, 2024
27 May 2024 — 31 May 2024
The big move this week was IDP Education (IEL), with short interest collapsing from 16.97% to 12.78% (-4.20%). Lithium is still the ASX’s favourite short theme — Pilbara (PLS) remains #1 at 21.38% even after a small trim (-0.22%) — while new shorts pushed into Chalice (CHN) (+1.20%) and a handful of quality growth names like Pro Medicus (PME) (+1.33%).

A 4.20% weekly drop in short interest doesn’t happen by accident. Shorts didn’t just “ease off” IDP Education (IEL) — they ran for the exits, taking the position down from 16.97% to 12.78% in one week. That sort of unwind usually screams positioning change: either the near-term bear case has been crowded enough, or traders are stepping aside ahead of a catalyst where the risk of a sharp rebound is too high.
PLS is still the main event at 21.38% short, even after a modest -0.22% WoW trim. The message is clear: the market still wants to fade lithium exposure, and PLS is the liquid, index-relevant way to do it. LTR (9.99%, +0.14%) and SYA (9.41%, +0.17%) reinforce the same sector bet — small increases, but the shorts haven’t left. IEL (12.78%, -4.20%) is the standout reversal. The most likely read is shorts taking profit after a strong run in the bear thesis (student mobility, policy risk, and currency sensitivity are the classic pressure points for this name). When a position is that crowded, it doesn’t take much to trigger a scramble. SYR (10.72%, -2.10%) also saw a meaningful cover. That’s consistent with traders reducing exposure to higher-risk materials names after a period of heavy pessimism. FLT (9.85%, -1.25%) had shorts trimming too. Travel is a classic consumer discretionary battleground when rates stay higher for longer — but this week’s move suggests some are banking gains rather than pressing. On the other side, CHN (9.50%, +1.20%) is now firmly in the top-10 and still climbing. Exploration/development stories are magnets for shorts when funding risk and commodity volatility dominate the narrative. Chalice’s own Gonneville materials (e.g., its pre-feasibility study presentation: https://chalicemining.com/wp-content/uploads/2025/12/61302010.pdf) underline how much execution sits between “resource” and “returns” — and shorts are leaning into that gap. HLS (8.34%, +0.57%) is creeping higher as well. Diagnostics can look defensive, but it’s also a margin-and-regulation business. Shorts lifting here suggests the market is still sceptical on earnings quality and competitive pressure.

The risers were punchy. Cooper Energy (COE) jumped from 1.35% to 2.99% (+1.64%). That’s a big move for an energy mid-cap and reads like event-risk positioning — energy names can swing hard on operational updates, pricing assumptions, or project timelines. PME moved from 1.85% to 3.18% (+1.33%). When shorts step into a high-quality, high-multiple healthcare tech name, it’s usually a valuation call rather than a “business is broken” call. With rates still restrictive, the market keeps testing how much investors will pay for growth. SQ2 (Block CDI) lifted from 1.63% to 2.84% (+1.21%). That fits the global fintech playbook: sensitive to US rate expectations and risk appetite. LOV rose from 0.66% to 1.52% (+0.86%). That’s not a huge absolute short, but the direction matters. Retailers with global store rollouts are exposed to consumer spending and cost pressures; shorts are starting to sniff around. The fallers were even more telling. BLD collapsed from 2.98% to 0.17% (-2.81%). That’s basically a short thesis being abandoned. Whether it’s corporate action speculation or simply the trade no longer working, the speed of the cover suggests shorts didn’t want to be there. ACL fell from 9.87% to 8.12% (-1.75%). Pathology has been a crowded short theme at times; this looks like risk reduction rather than a full change of mind. ACL’s own materials emphasise digital service delivery (e.g., eHealth brochure: https://www.clinicallabs.com.au/media/4978/ehealth-a4-brochure-2022-aclmar-bf-nat-04236-digital.pdf), but the market is still debating whether tech improvements can offset industry pricing and cost pressures. TYR dropped from 2.24% to 0.73% (-1.51%). That’s a meaningful cover in payments — either shorts are taking profit, or the near-term catalyst calendar has become less attractive for a bearish bet.
Zooming out, the ASX short book still has a clear shape. Materials dominates the top end: PLS, SYR, LTR, WGX, CHN, SYA all sit in the top-10 most shorted. That’s the market expressing two views at once: (1) lithium remains the preferred macro short, and (2) pre-cashflow development stories are vulnerable when capital is expensive. At the same time, shorts are selectively rotating into “expensive growth” (PME) and consumer names (LOV), which fits a higher-for-longer rates backdrop. Meanwhile, the big covers (IEL, BLD, SYR) suggest some crowded trades are being de-risked rather than aggressively added to. Market-wide, the average short position is only 1.03% across 680 stocks and the period average change was -0.02%. So the action is concentrated: a handful of names are doing the heavy lifting for sentiment.
Next week, watch for any macro shift that hits rates expectations (RBA messaging and bond yields) because it feeds straight into PME/SQ2-style valuation shorts. And keep an eye on commodity tape action — lithium-linked shorts are still crowded, with PLS sitting at 21.38%.
IDP Education (IEL): short interest fell from 16.97% to 12.78%, a -4.20% move in a single week.
Pilbara Minerals (PLS) at 21.38% short, down slightly by -0.22% week-on-week.
Yes. PLS (21.38%), Liontown (LTR, 9.99%) and Sayona (SYA, 9.41%) are all heavily shorted, with LTR and SYA edging higher WoW.
Cooper Energy (COE) +1.64% to 2.99%, Pro Medicus (PME) +1.33% to 3.18%, and Block CDI (SQ2) +1.21% to 2.84%.
Very unusual — most stocks move in small increments week to week, and the report’s period average change was just -0.02%, which highlights how extreme IEL’s -4.20% unwind was.
