Key takeaways
Big spike in short interest for Clinuvel Pharmaceuticals. The stock dipped 21% between 28-29 August after the company reported weaker-than-expected FY25 results. While seasonal strength and low material costs supported margins, these gains were viewed as temporary. The unchanged dividend and minimal buyback activity continued to draw criticism from analysts, as management's growing cash pile was increasingly seen as poorly utilised.
Audinate is another reporting season loser attracting bearish bets. The stock dipped 20.7% on 18 August after the company reported a soft FY25 result and wide FY26 guidance miss, with net profit growth guidance of 13-15% vs. Morgan Stanley estimates of 21%.
Other reporting season losers on the list include Ramsay Healthcare, IPH, Guzman Y Gomez and Ora Banda Mining.

Key takeaways
Patriot Battery Metals experienced a one-day spike in short interest to 7.0%, now back down to 4.2%. This is in-line with recent short interest levels.
Uranium names like Paladin Energy, Boss Energy and Deep Yellow saw significant short covering, though the catalyst remains unclear. A key recent sector driver was Cameco's production cut announced on 29 August, when the world's largest uranium miner reduced its 2025 forecast to 14–15Mlbs U3O8 (down from 18Mlbs) due to development delays and slower ground freezing.
Collins Food is crushing short sellers following its AGM trading update, which showed sales momentum accelerating across Australia and Europe over the first 18 weeks. The stock has surged 42% since its 24 June full-year result, driven by a margin turnaround from deflation in select commodities, improved rostering, reduced wastage, and productivity initiatives.
