HUBC has cratered 98% in a single month, leaving short sellers sitting on extraordinary exposure — and raising questions about what, if anything, is left to short against.
The price collapse is the defining fact here. HUB Cyber Security closed at $0.1368 on May 15, down from implied levels near $6 just a month ago. The weekly loss alone reached 45%. The stock traded as high as $114 within the past three months, making the current print a near-total wipeout. RSI-14 has compressed to 28.75 — deeply oversold territory — though oversold readings in micro-cap stocks in freefall carry little mean-reversion weight on their own.
The short positioning story is, paradoxically, the most technically striking feature of this name. Short interest now registers at 115% of the estimated free float — a figure that, taken at face value, implies more shares are borrowed and sold short than technically exist in the tradable float. That reading came down sharply from the extraordinary peaks reached in mid-April, when SI hit 939% of the float on April 17, a period that coincided with intense borrow demand and likely reflected a squeeze and subsequent partial unwind. The week-on-week change shows a 29% drop in shares shorted — some of that positioning has been covered — but the absolute level remains extreme. Cost to borrow is running at roughly 83% annualised, a punishing rate that has held in a tight range between 75% and 90% for most of May. Borrow availability is effectively zero: 0% of SI remains available to new shorts, meaning the lending pool is entirely consumed. The 52-week borrow peak was 100% utilisation, and conditions remain close to fully consumed.
The ORTEX short score sits at 80.4, a persistently elevated reading that has barely moved over the past ten days despite the sharp fall in the share count of shorts. That score reflects a structure where short interest is high relative to float, cost to borrow is expensive, and availability is exhausted — characteristics that, in combination, describe a deeply stressed borrow market rather than a conventionally crowded trade. Days-to-cover is just 1.6 days at current volume, keeping short-squeeze mechanics theoretical rather than imminent.
Institutional ownership tells its own story. The top holder list is made up almost entirely of individual names — Mboyc Holdings, Jonathan Strauss, Jon Walden — holding single-digit percentage stakes, with no conventional institutional asset manager owning more than a rounding error. The top fifteen disclosed holders combined hold roughly 45% of the company by reported share count, suggesting the free float is very narrow. That structural thinness is likely what amplifies both the short interest percentages and the borrowing costs.
Earnings history adds limited comfort. The two prior events with price data show a one-day move of -8% and a -5% drop respectively, with five-day moves of -10% and -23%. A further event on record from May 15, 2026 — flagged in the data — has no price-reaction data attached yet. The next scheduled results are listed as FY 2025, with no confirmed date.
The number to watch is borrow availability. At effectively zero, any further increase in short demand would require a stock-loan market intervention to facilitate — and any return of lending supply could signal a change in the positioning dynamic.
