Scilex Holding Company enters May after one of its most violent weekly moves in recent memory — a 58% rally driven by a headline deal, yet one where the short and borrow data tell a story of quiet disengagement rather than a forced squeeze.
The catalyst is clear. On April 27, Datavault AI announced a $120 million cash contribution and revenue participation agreement with Scilex. The stock had been drifting in the low single digits; it closed Friday at $10.58, up nearly 59% on the week. A token dividend — 81.4 million "Dream Bowl" digital collectibles distributed to stockholders — added noise earlier in the month, and a $500 million shelf filing in mid-April had already primed the news flow. The stock was primed for a re-rating; the Datavault deal provided the spark.
What's notable is what shorts did not do. Short interest, at around 2.8% of the free float, is too small to have driven the move in either direction. Net short exposure has actually drifted lower over the past month, down roughly 13%, with the clearest drop coming in late March and continuing through mid-April. As the stock rallied, estimated shorts declined further — a quiet unwind rather than a scramble. Cost to borrow has followed the same direction, halving from above 8.5% in late March to just 4.7% now. With availability running at 471% of short interest — ample borrow relative to the shares already out — there is no lending-market stress here. Shorts who wanted out could leave without friction.
The factor scores sketch a mixed picture. The EPS surprise rank is the standout: at the 97th percentile, Scilex has consistently beaten estimates, a number that at least partly explains why the Street maintains some constructive positioning. The short score of 47 is unremarkable, sitting near the midpoint of the 0–100 range and little changed over the past two weeks. DTC ranks in just the 18th percentile, meaning the days-to-cover figure is low relative to peers — there is no meaningful cover-or-die dynamic lurking beneath the surface. Analyst coverage is stale (the most recent data is from mid-2025), so it cannot be relied upon here.
Earnings history adds a layer of caution. The most recent print on April 10 saw the stock fall nearly 15% the following day before recovering to just a 1.6% loss over five days. The prior two Q prints in late 2025 were similarly volatile: a 16% gain on one occasion, a 13% drop on another. The next event is pencilled for June 24, giving the rally roughly seven weeks of runway before the market demands a fundamental update to justify the new price level.
The ownership structure is concentrated. The largest single holder — SCLX Stock Acquisition JV LLC — holds just over 20% of shares with no reported change. Armistice Capital, a known healthcare-focused hedge fund, added more than 400,000 shares in December, moving its stake to 6.8%. With a float this thin and a market cap that ORTEX puts at roughly $74 million, even modest institutional flows carry outsized weight. What to watch is whether Armistice and other active holders treat the rally as an exit or whether the Datavault revenue participation agreement generates any follow-on institutional interest ahead of the June earnings date.
