SmartKem, Inc. heads into its May 22 earnings print with short positioning that has exploded from near-zero to its highest level in months — all while the stock trades near pennies.
The short interest story is the headline here. At under 0.2% of the float in early April, SMTK was essentially unshorted. By May 18 that figure had surged more than 30-fold to 9.9% of the float on the raw estimate — though the ORTEX daily estimate, which accounts for float size, places it closer to 3.0% of float on a best-float basis. Either way, the directional signal is unmistakable: bearish conviction has built rapidly and persistently throughout May. Cost to borrow is running at around 10.6%, elevated but having eased back from a peak above 14% in mid-April. Availability has loosened considerably — from just 27% on May 8, a genuinely tight level, back up to 115% today — suggesting the squeeze pressure that briefly gripped the lending market a fortnight ago has since unwound. The stock itself is down 27% over the past month, down 9.5% on the week, and hit $0.25 at Tuesday's close.
The bear case is structural and well-established. SmartKem remains a pre-revenue semiconductor materials company developing organic thin-film transistor technology. Its ORTEX stock score carries near-zero momentum and deeply negative return on assets, reflecting substantial cash burn with no near-term revenue inflection visible. The short score of 54.4 is mid-range but has been elevated for weeks, suggesting this is not reactive positioning but a deliberate build. The market cap has compressed to roughly $6 million — micro-cap territory where liquidity is thin and any negative newsflow can move the price sharply. Bulls, if they exist in meaningful size, would point to the technology's potential in flexible electronics and the fact that the borrow market has loosened, reducing any remaining squeeze pressure on the short side.
Past earnings events have been violent in both directions. The April 13 print produced a 6.7% gain on day one but a 17.7% loss over the following five sessions. An April 8 event — likely a material announcement rather than a scheduled earnings release — generated a 46% single-day spike followed by a 40% five-day gain. The March 27 quarterly print saw an 8.4% drop on the day. The pattern is one of extreme two-way moves, amplified by thin liquidity and a micro-cap structure that makes the stock highly sensitive to sentiment shifts.
Thursday's print is therefore a test of whether the aggressive short build of the past six weeks reflects a well-founded view on cash position and commercialisation timelines — or whether any positive signal, however marginal, is enough to disrupt a still-modest but rapidly-built short base.
