Greenidge Generation Holdings posted a 21% gain over the past week to close at $1.47, its best run in months. The stock reported Q1 results after the close on May 15, beating year-ago comparisons — but with short sellers still rebuilt from a five-week high and an earnings call confirmed for May 22, the rally has entered a phase where positioning matters as much as fundamentals.
The short interest story is the central tension here. At 5.1% of the free float, shorts are not extreme in absolute terms — but they have been climbing. Short shares rose roughly 6% over the past week alone, after jumping nearly 27% in late April from a low near 530,000 shares. That rebuilding happened as the stock was already in the early stages of its rally, suggesting a cohort of bears added into price strength rather than covering into it. Borrowing costs, meanwhile, have eased — the cost to borrow has fallen 19% over the week and 26% over the month, now running at a modest 1.94% annually. Availability is tighter than it looks, though: borrow is running at roughly half its 52-week peak utilization, meaning there is still room for additional short positioning to build.
ORTEX's short score for GREE came in at 60.1 on May 14, easing from a recent high of 63.0 on May 7. That gentle decline tracks the cost-to-borrow softening, but the score remains well above 60 — a level that reflects a non-trivial short conviction. The short score rank lands in the 12th percentile for its sector, meaning a meaningful minority of comparable companies carry higher short pressure. Days-to-cover of 4.8 days (per the most recent FINRA fortnightly) suggests an unwind would not be painless.
The catalyst backdrop explains why both bulls and bears are staying engaged. Q1 revenue came in at $20.8 million, up from $19.2 million a year earlier, and the EPS loss narrowed to $(0.29) from $(0.40). Those are the right directional moves. An S-3 shelf registration filed the same evening introduces a potential overhang — shelf filings at this market cap and share price often signal the company is prepared to raise equity, which weighs on small-float names. The next formal earnings call is scheduled for May 22, giving traders a second catalyst within the same week. The most recent pre-report earnings history is thin but pointed: the November 2025 print produced a one-day decline of nearly 15%, while the March 2026 result saw only a -2.8% next-day move — a clear improvement in market reaction even with the stock still loss-making.
Insider activity reflects insiders positioning for that trajectory rather than conviction in a near-term recovery. The CEO, CFO, and President all sold shares in March at $1.38 — slightly below the current price — in small but coordinated transactions. The net insider position over the past 90 days is a net sale of around 100,000 shares worth roughly $144,000. These were low-significance trades by value, likely tax-related or automatic plan sales, but the direction is worth noting given the stock's simultaneous rally.
Peers in the crypto-adjacent and small-cap compute space had a rough week. BTCS fell 13.7% on the day, BTBT dropped 15.3%, and EXOD shed nearly 21% over the week — making GREE's 21% gain look notably divergent. Analyst coverage remains stale; the most recent published target of $4.00 dates to mid-2024 and should not be treated as a live valuation anchor. What to watch next is whether the May 22 earnings call addresses the S-3 shelf directly — and whether the shorts who rebuilt into this week's strength begin to cover or add following the call.
