The lending market for GPRK just flipped dramatically. Availability collapsed to 58% overnight — down from 200% the day prior — as the borrow pool dried up and cost to borrow surged 146% in a week. At the same time, options traders are running one of the most bullish postures the stock has seen in a year.
Cost to borrow hit 2.48% on August 27. That is the highest reading since late July and nearly two-and-a-half times the level from a week ago.
The availability picture tells the sharpest part of the story. On August 26, availability stood at 200% — meaning twice as many shares were available to borrow as were already lent out. By August 27, that had fallen to 58%. Every share in the lending pool is now accounted for, with only a thin cushion remaining.
This pattern has appeared before. Availability dipped into the 20%–30% range repeatedly through late July and early August, before briefly normalising in mid-August. The current tightening has now snapped back to that same extreme zone.
Short interest itself is not the driver here. At 1.51% of free float, it remains low and has actually fallen 14% over the past week. The borrow squeeze is about supply contracting, not demand expanding.
The put-call ratio hit 0.088 on August 27. That is 2.2 standard deviations below its 20-day mean of 0.105.
For context, the 52-week PCR high is 1.21. The current reading of 0.088 is close to the 52-week low of 0.059. Options positioning is firmly call-heavy — participants are paying up for upside exposure, not protection.
The founder and Vice Chairman, James Park, sold 120,000 shares at $9.65 on August 10 — a $1.16M transaction. Park is the second-largest institutional holder at just over 20% of shares outstanding. The sale is recent and notable in scale, though the stock has continued to drift modestly higher since then, now trading at $9.85.
Renaissance Technologies trimmed 355,553 shares as of June 30. VR Advisory Services moved in the opposite direction, adding 1.15M shares in the same period — the largest proportional build among active managers in the snapshot.
The ORTEX short score sits at 54.3, in moderate territory. EV/EBITDA of 2.89x and a PE of 6.4x keep valuation tight by historical standards for the sector.
