Skycorp Solar Group has just lived through one of the more dramatic short-squeeze cycles seen in a micro-cap name this year — and the aftermath is almost as striking as the peak.
The story starts with a catalyst. On May 4–5, Skycorp announced a $20M acquisition of Nanjing Cesun and a $3M private placement. The stock went vertical, triggering circuit breakers on the way up, and ultimately rallied more than 200% between late April and its intraday high near $20. Short sellers who had been positioned at 27% borrow costs suddenly found themselves paying 809% APR to hold those bets. By May 5–6, availability had collapsed to 0% — every share in the lending pool was already borrowed, the tightest the market had been all year. Short interest peaked around 450,000 shares on May 5 before a rapid unwind began. By May 14, estimated short shares had fallen 98% from that peak to just 8,289 — one of the sharpest collapses in short positioning recorded over any seven-day window this year.
The lending market tells a tale of two regimes. Before the catalyst, borrow was cheap and plentiful — cost to borrow sat around 27% APR through most of April, with availability running in the hundreds of percent (ample supply). The acquisition news flipped that entirely. Cost to borrow exploded more than 30-fold in a week to 847–861%, and availability hit zero. Now, with short interest having evaporated, availability has rebounded to around 449% — borrow supply is loosening again — but the cost to borrow remains pinned above 800% APR. That persistent premium signals lenders are still pricing in tail risk even as the short base has largely fled. The ORTEX short score, which hit 81 on May 5–6, has fallen back to 51, reflecting the rapid shift from extreme positioning to near-neutral.
The stock has given back a significant portion of its gains. From a peak near $20, PN has retraced to $4.31 — down 26% on the week alone and off roughly 78% from the high, though still up 66% over the past month relative to where it started. The earnings reaction history adds some context here: the last two material announcements produced intraday moves of -33% and -13% respectively, while the February 2026 release was comparatively benign at +2.4%. The pattern suggests this name can deliver outsized single-day moves around catalyst events in either direction.
The ownership picture is concentrated and thinly institutionalised. The top three holders — Weiqi Huang, Gaokui Zhang, and Wenshan Xie — collectively hold around a third of shares outstanding, all with zero reported change in their positions. Institutional participation is minimal, with Citadel and Two Sigma holding under 3,000 combined shares. That thin float is precisely what made the May squeeze so violent: a small number of short shares against a mostly locked-up register amplified every price move. The FINRA fortnightly figure confirmed official short interest at just 7,402 shares as of April 30, underlining how micro the actual float is in practice.
No next earnings date has been flagged, and there is no analyst coverage to cite. What to watch now is whether the cost to borrow normalises back toward its pre-squeeze range of 27% or whether it stays elevated — a sustained premium above 400% would suggest the lending market still sees reason to price in further volatility despite the near-total short position washout.
