Short interest signals were sharply divided this week. Big increases hit FCEL, URA, and SOLS, while covers accelerated in ASIC, FTEC, and PB. Borrow markets flashed stress in several small-caps, with LVWR and VFS hitting near-zero availability.
FCEL — SI hits 34.4% of float, up 37.5% in one week. FuelCell Energy short interest reached a three-month high. The stock climbed on analyst upgrades. Bears are pressing harder despite the positive catalyst.
SOLS — SI surges 76% in one week to 6.2% of float. The move is aggressive in percentage terms. Utilization sits at just 2.5%, with availability at 4,019%. Shorts are adding, but borrow is not yet constrained.
UNG — SI drops 12.1% in one day to 9.9% of float. That one-day unwind reversed a weekly surge of 88%. Natural gas short sellers ran hard, then covered fast. Volatility in the borrow signal remains elevated.
URA — SI jumps 29% in one week to 2.76% of float. Uranium ETF short interest is building. Nuclear energy demand shifts drove sector volatility. Bears are positioning for a pullback.
FRBT — SI halves in one week to 64,087 shares. Shorts exited at pace. Cost to borrow rose to 21.4% even as availability hit 8,532%. The borrow market is pricing risk despite the cover.
ASIC — SI falls 22.7% to 0.48% of float. Availability sits at 1,732%. Analyst upgrades drove the stock. Bearish pressure is effectively gone.
PB — SI drops 24% to 4.76% of float, CTB falls 33% to 0.26%. Prosperity Bancshares saw a clean short unwind. Borrow costs dropped in tandem. The move signals a clear shift in sentiment.
Energy names drew the most attention. UNG saw an 88% weekly SI surge before a sharp one-day reversal. URA built a 29% weekly increase. FCEL reached a three-month SI high. Short sellers were active across the energy and clean energy space throughout the week.
Tech ETFs saw short covering. FTEC SI dropped 29% to 0.21% of float — near multi-month lows. The broader tech sector pulse data showed covering across FTXL, SKYY, and FCOM. Demand-side strength kept bears on the back foot.
Borrow stress flared in small-caps. LVWR cost to borrow hit 588% with availability at zero. VFS borrow hit maximum tightness. UFO short interest reached 40% of float with a rapidly tightening borrow pool. These three names now face the most constrained short conditions in this week's data.
Several names showed multi-signal alignment this week.
GRPN triggered two separate convergence flags. Short interest spiked to 32.5% of float. Options buyers turned aggressive. Bears added shorts but now face difficulty exiting. Earnings are ten days away — a combination that raises squeeze risk.
IONQ hit a borrow pool near-empty signal as SI climbed to 14%. Shares available to borrow are thin. Any further short covering could accelerate.
UNG appeared in both the top SI movers and convergence data. Short sellers ran and then covered in the same week. The convergence note is titled "Short Sellers Keep Running" — the intraweek reversal adds noise to the directional read.
DHI saw shorts re-enter post-earnings. Options hedging persisted. The convergence flags bears treating the post-results dip as a re-entry point.
SPCX showed analyst disagreement alongside locked-in bears, with earnings eight days out. A split analyst picture and constrained borrow create a binary setup into results.
LVWR borrow hit zero with cost to borrow at 588%. No shares are available. Any attempt to add shorts would require locating stock elsewhere — practically impossible at current levels.
WBD options hedging spiked ahead of earnings. Short sellers have not yet moved in size, but the options signal leads.
