ASX 200 Short Sellers Target Reporting Season Misses

Highlights

• IPH and Monash IVF Group experience sharp increases in short interest following earnings updates

• Reliance Worldwide and Inghams see rising shorts amid weaker performance and outlooks

• Clinuvel and Novonix lead the list of most covered stocks with notable reductions in short positions

This week’s short interest data, covering activity between late July and late August, reflects a wave of short seller activity concentrated around ASX-listed companies that reported results viewed unfavourably by the market. While entities like IPH (ASX:IPH), Monash IVF Group (ASX:MVF), and Inghams Group (ASX:ING) attracted fresh shorts, others such as Clinuvel Pharmaceuticals (ASX:CUV) and Novonix (ASX:NVX) experienced notable reductions in bearish positioning.

The short interest rankings offer insight into how sentiment is evolving post-earnings, especially across sectors affected by external macroeconomic or operational headwinds. All mentioned companies are constituents of the ASX 200.

Which companies topped the most shorted list?

Boss Energy (ASX:BOE) maintained its position as the most shorted stock, despite a reduction in week-on-week positions. Paladin Energy (ASX:PDN) and Pilbara Minerals (ASX:PLS) also featured among the most targeted names. Among non-resources names, IDP Education (ASX:IEL) and Polynovo (ASX:PNV) saw elevated levels of short activity.

Lifestyle Communities (ASX:LIC), Corporate Travel Management (ASX:CTD), and PWR Holdings (ASX:PWH) rounded out the top list, with the latter recording a noticeable uptick in short positions.

Which stocks recorded the biggest rise in short interest?

Short interest in IPH (ASX:IPH) surged following its latest financial year update. The company cited sustained competitive challenges in Australia and New Zealand, softness in key overseas jurisdictions, and cautious sentiment around future earnings. Monash IVF Group (ASX:MVF) also experienced a meaningful increase in short positions after providing forward guidance below market expectations.

Reliance Worldwide Corporation (ASX:RWC) and Inghams Group (ASX:ING) followed a similar pattern. Both companies issued updates that included outlooks perceived as cautious, which coincided with notable price movements and intensified short interest.

Lake Resources (ASX:LKE), Megaport (ASX:MP1), Telix Pharmaceuticals (ASX:TLX), and Peninsula Energy (ASX:PEN) also attracted more short activity, though the increases were less aggressive.

What’s behind the short interest surge in Inghams and Reliance Worldwide?

Inghams Group (ASX:ING) reported a soft finish to the financial year, with challenges including a weaker product mix, price pressure, and softer consumer demand. The company’s outlook indicated the earnings trajectory might rely heavily on a rebound in the latter half of the next financial year.

Reliance Worldwide Corporation (ASX:RWC) was impacted by guidance highlighting continued headwinds from global trade friction and slowdowns in its key overseas markets. The outlook flagged persistent pressure on margins and volumes.

Which stocks saw the most short covering?

Clinuvel Pharmaceuticals (ASX:CUV) led the pack in short covering, with bearish sentiment retreating sharply. This was followed by Novonix (ASX:NVX), Arafura Rare Earths (ASX:ARU), and Temple & Webster Group (ASX:TPW), all of which experienced a reduction in short activity.

Interestingly, some companies that also disappointed during reporting season, such as IGO (ASX:IGO) and Origin Energy (ASX:ORG), saw moderate short covering. This suggests that despite earnings-related concerns, market sentiment may already have adjusted to new expectations or short sellers opted to take profits.

What trends are emerging in short selling?

The data reveals that short sellers are increasingly active in names that missed expectations or issued cautious forecasts for the upcoming financial year. These include companies impacted by cyclical sectors, consumer demand volatility, and international exposure. On the flip side, covering activity is appearing among speculative stocks and others that may have stabilised post-earnings.

Among uranium, lithium, biotech, and digital infrastructure names, market activity remains dynamic as traders adjust to new performance signals.
