SMTK shorts explode as dilution looms

SmartKem, Inc. heads into the week of May 2 with one of the sharpest short-interest spikes of any stock on Nasdaq — a 20-fold surge in just five sessions, set against a backdrop of dilution risk and a Nasdaq compliance warning.

The short-interest story is the entire story here. Estimated short interest rocketed to 8.65% of the free float by April 30, up from less than 0.5% just a week earlier. The single-day jump of 325% on April 30 alone pushed the position to its highest level on record for this stock. The driver is almost certainly the equity offering machinery SmartKem set in motion this month: on April 17 the company filed an S-1 to issue and sell up to 146.8 million common shares to Keystone Capital Partners — a classic at-the-market dilution vehicle that hands short sellers a natural hedge. A separate prospectus filing appeared on April 27, adding more fuel. Shorts are not crowded by absolute standards — 8.65% of float is meaningful but not extreme — yet the speed of the build is what stands out.

Borrow conditions have tightened in step with the position build, but not dramatically so. Availability in the lending market is running at roughly 84% of short interest, which means there are still more shares available to borrow than are currently out on loan — not a stress level. Cost to borrow has crept back to around 11.8% annualised after spending much of March above 20%; the six-week trend is actually one of easing, not tightening. The ORTEX short score has jumped to 54.4 from 33 a week ago, reflecting the sharp positional shift, but borrow availability says the lending market is not yet under pressure. These two signals tell different parts of the same story: new shorts are arriving fast, but the pool is not exhausted.

The corporate picture adds context. On April 23, SmartKem disclosed a notice of delisting or failure to satisfy a continued Nasdaq listing standard — a material event for a $5 million market-cap stock trading at $0.24. The stock bounced 21.8% on May 1, partly reversing the week's 13% loss. Prior earnings prints have been violent in both directions: a one-day gain of 46% on April 8, a 7% rise on April 13, and an 8% fall on March 27. The next earnings event is flagged for May 15.

What to watch is whether the Keystone Capital at-the-market facility accelerates share issuance as the stock recovers, and whether the short position — already at a record high — continues to climb ahead of the May 15 earnings date.
