Artelo Biosciences heads into its next earnings event on May 20 with a story defined entirely by reversal — shorts have fled, borrow costs have halved, and the stock has collapsed anyway.
The most striking development this week is how fast the short-side unwound. Short interest fell 92% in a single week, dropping from around 137,000 shares to just 10,700 — roughly 0.53% of the float. That collapse follows a sustained build that peaked near 600,000 shares in late April. Whatever drove that positioning — likely the dilutive equity offerings and deteriorating fundamentals — those shorts have now largely closed. The borrow market reflects the reversal: cost to borrow has eased to 391%, down sharply from peaks above 900% in early April. That number still sounds extreme, but the directional move is unambiguous. Availability in the lending pool has opened up substantially, with the 52-week high utilization of 100% (reached in mid-April) now replaced by a reading near 6% — meaning the vast majority of lendable shares are currently sitting idle, a complete reversal from a market that had every share out on loan just weeks ago.
The shorts exited, but the stock did not rally. ARTL closed Friday at $1.84, down 21% on the day and 28% on the week. The Q1 earnings release on May 14 was the trigger — EPS came in at -$4.00, missing the consensus estimate of -$1.57 by a wide margin. The one-day reaction of -20% matches that print. On a one-month basis the stock is down 66%, and year-to-date the drawdown reaches nearly 50%. That context matters: this is a micro-cap biotech that has been in structural decline, running a series of equity offerings since March to fund operations. A 1-for-3 reverse stock split in March bought limited time. The company announced this week it will terminate its at-the-market offering agreement effective May 18 — closing off the most recent source of dilutive capital.
The factor scores capture the paradox neatly. The EPS surprise score ranks in the 99th percentile — but that measures the company's history of beating estimates, not what happened this week. Days-to-cover ranks in the 97th percentile. Yet the short score has dropped sharply from 63-66 just ten days ago to 43.6 now, reflecting that short positioning has collapsed faster than the stock. The RSI sits at 26.7 — deeply oversold territory — though for a stock burning through cash and closing funding channels, technical readings carry limited weight without a positive catalyst.
The institutional picture offers little support. The largest disclosed holder is Intracoastal Capital with just over 8.6% of shares, fully acquired by early April. A Schedule 13G filed by Armistice Capital appeared this week, but the small size of the float means even modest institutional activity registers at meaningful percentage levels. No analyst coverage with recent price targets is available for this stock. Insider activity in the database dates back to 2022, with the last significant purchase by the founder/CEO at prices around $4.00 — well above where the stock trades today. That data is too stale to be meaningful for this note.
The next event is a Q1 2026 earnings call scheduled for May 20. The setup into that event is a stock trading near multi-year lows, freshly off a large earnings miss, with its at-the-market dilution mechanism shutting down, borrow conditions wide open, and short interest near negligible levels. The prior earnings history shows one dramatic outlier — a 174% one-day gain on March 27 after what appears to have been a catalyst-driven move — but the two prints on either side of it produced losses of 2-3% on the day and 11-12% over five days. What to watch on May 20 is whether management addresses any new funding strategy now that the offering agreement terminates, given that is the most pressing operational question the company has left to answer.
