Welcome back to the Short Seller Series – A recap of the most heavily shorted stocks on the ASX and those experiencing significant changes to short interest over the past week.

Most Shorted
Telix has become the most shorted stock on the market, with short interest jumping to a record 16.16% from 11.10% at the start of the year. The once high-flying biotech fell almost 75% between 26 February 2025 and 16 February 2026, but has since bounced ~71% from the low. It's interesting to see short sellers still piling aggressively into recent strength. More recently, Telix launched a US$550 million convertible bond offering, with proceeds earmarked to repurchase existing bonds due 2029. Morgan Stanley views this as removing an overhang for the stock, alongside the recent "strong" 1Q26 result.

Rising Shorts
4DMedical also saw a big jump in short interest, an understandable move given the $2.9 billion market cap company is trading on eyewatering multiples (unprofitable, with just $2.8 million in revenue reported for 1H26). There have been no major company updates in recent weeks, though the stock was added to the S&P/ASX 200 from Monday, 20 April. Other tech and growth-heavy names including CAR Group, Pinnacle, Generation Development and TechnologyOne have also seen a notable uptick in short interest.

Droneshield saw a slight pullback in shorts after short interest hit a record 12.66% on 13 April. The stock is up 22.5% year-to-date in what's been a relatively calm period for the share price, paired with continued momentum in the business. Droneshield's 1Q26 report (22 April) flagged revenue growth of 121% year-on-year to $74.1 million, with a $2.2 billion potential sales pipeline (up ~5% quarter-on-quarter). Elsewhere, defence peer Electro Optic Systems and a handful of resource names saw a slight decline in short interest.
