Uranium sector volatility drives short interest changes. The sector continues to experience significant turbulence, with the NYSE-listed Global X Uranium ETF serving as a useful barometer. Over recent weeks, the ETF rallied 25% to all-time highs (1-15 Oct), then dipped 20% (16-22 Oct), bounced 15% (23-29 Oct), before falling as much as 23% (30 Oct - 14 Nov). This extreme volatility is seeing a pullback in short interest for Paladin Energy and an increase in Boss.

Key takeaways
James Hardie saw a sharp spike in short interest on 6 November when the stock dipped as much as 17% (closing 12.6% lower) following disappointing updates from US home-improvement peers including Trex, Owens Corning, Home Depot, and Lowe's. The biggest catalyst was decking manufacturer Trex, which dropped as much as 30% after warning of "continued weakness" in the repair and remodeling sector, according to Bloomberg. With James Hardie shares already down 49% year-to-date, the market appears to be positioning for further deterioration.
Short sellers have aggressively targeted G8 Education, with short interest surging from around 1.3% in September to a record high of 7.3% last week. The company has faced mounting challenges since flagging in early July that one of its employees was charged with more than 70 offences. The stock now trades at its lowest level since August 2020, weighed down by both this incident and broader sector headwinds including softer occupancy, affordability pressures, and competitive dynamics. On 4 November, the stock fell 13% after management downgraded FY25 earnings guidance to $91-98 million, significantly below consensus estimates of $110.9 million (15% miss at the midpoint) and prior guidance of around $115 million (18% miss at the midpoint).

Key takeaways
Arafura's short interest has dipped from recent highs of 5.4% (3 Nov), potentially reflecting profit taking from short sellers. The stock is down almost 60% from its brief peak of 62 cents on 21 October. Most rare earth stocks are down 30-50% from recent highs following a strong rally earlier this year.
Elders experienced a modest pullback in short interest after the stock declined in eight of ten sessions between 24 October and 7 November. This followed the company's October downgrade of FY25 EBIT guidance to $142-146 million versus consensus of $161.7 million, representing a 10.9% miss at the midpoint. CEO Mark Allison attributed the shortfall to dry conditions impacting the Retail business, particularly in South Australia and Western Victoria, with drought conditions persisting through April and May.
