Key takeaways
No major changes among the top shorted stocks
Boss Energy short interest edged lower, though the stock fell roughly 20% between March 3 and 9 amid broader market weakness that has erased most year-to-date gains across the uranium sector. Macquarie retained its Underperform rating earlier this month, noting: "We still hold the view that Honeymoon will be challenging, and wide spacing trials carry risk. A complicated proposition; we believe investors should wait to see more definitive results from wider spaced leach trials first before making an investment decision."

Key takeaways
McMillan Shakespeare recorded the largest week-on-week increase in short interest for the second consecutive week. Its 1H26 result (23 Feb) came in slightly below expectations, with the miss largely driven by a 20.9% year-on-year decline in EBITDA from the Plan and Support Services segment. After the result, Macquarie downgraded the stock to Neutral from Outperform, flagging the risk that the government could cap the EV fringe benefit tax as early as the May 2026 budget, alongside ongoing NDIS policy uncertainty. The stock has fallen a further ~7% since the result.
Silex is a uranium technology company focused on laser enrichment, with applications spanning nuclear power, silicon enrichment for quantum computing, and medical isotope production for cancer therapies. The stock fell 33% in a single session on January 6 after its US licensee, Global Laser Enrichment, was selected for a US Department of Energy Innovative Technology Award worth up to $28 million, but missed out on the far larger $900 million Low Enriched Uranium program that the market had been pricing in as a major catalyst. After trading sideways for several weeks following that drop, the stock has since broken below the January 6 low and fallen a further 20%.

Key takeaways
G8 Education has been in freefall. The stock tumbled 17% on the day of its 2025 full-year result (23 Feb), having already fallen 33% year-to-date heading into the print. The headline concern was a further deterioration in occupancy, with the 2025 average coming in at 65.8% and year-to-date occupancy sliding to 57.2%, down roughly 8 percentage points year-on-year. Despite that already severe one-day decline, the stock has fallen a further 33% since the result. Short sellers appear to be cashing in.
Bapcor looks like another name where short sellers are taking profits. The stock sold off 37.7% on February 27 after announcing both its half-year results and an emergency capital raise. The company posted a statutory loss of $104.8 million, with underlying NPAT collapsing 87% to just $5.5 million and revenue slipping 2.3%. Net leverage ballooned to 3.39x EBITDA from 1.65x the prior year, putting the company dangerously close to breaching bank covenants, and the dividend was scrapped entirely. The company also launched a fully underwritten $200 million equity raising priced at 60 cents per share, a 65% discount to the last close. The stock has spiraled another 27% since the half-year result.
