Key takeaways
Boss Energy's short interest has fallen to a five-month low, down 25% from its April peak. After a powerful March-to-May rally that saw large caps like Boss, Paladin Energy and Deep Yellow surge 50-90%, uranium stocks have traded sideways for the past month. Recent bullish catalysts include Trump's executive orders bolstering US nuclear energy under the Defense Production Act and Meta's 20-year, 1.1GW nuclear power purchase agreement with Constellation Energy. A key under-the-radar development occurred on 5 June when China General Nuclear Power Group signed a three-year uranium supply contract delivering over 1,200 tonnes annually from 2026-2028. The contract's base price of US$94.22/lb represents a 52% increase from previous agreements and sits well above current spot prices of US$70/lb.

Key takeaways
IDP Education's 48% plunge on 3 June erased $1 billion in market cap after the company slashed FY25 EBIT guidance by 25-30% below expectations. Regulatory headwinds including Canada's loss of IELTS monopoly, UK visa restrictions, and Australia's student caps drove the sharp decline in placements. While short sellers profited approximately $100 million, many took profits following the news, bringing short interest to its lowest level since March 2024.
Short interest continues to ease across a broad number of themes including beaten-up stocks (Nufarm, Healius), recapitalisation plays (The Star, Coronado Global), and critical metals (Chalice, Iluka Resources).
