OPEN heads into July with short sellers building aggressively and the borrow market moving sharply tighter — a combination that sets up an unusually charged technical backdrop ahead of August earnings.
The short position has become the defining feature of this stock right now. Short interest climbed to 22.8% of free float by June 30, up 24% in a single week and 35% over the past month. The pace of accumulation is the striking part: from roughly 128 million shares short in early June to 176 million by month-end, bears added the equivalent of nearly four weeks of prior short interest in about three weeks. FINRA's official fortnightly print put settlement-date shorts at 153.7 million shares with days-to-cover at 3.9 — elevated, and now likely an undercount given the daily-estimate trend. The ORTEX short score has jumped to 71.6, its highest reading in the available history window, up from 65.3 just two weeks ago. That score ranks OPEN in the bottom 4th percentile of the universe on short pressure — meaning almost every stock tracked carries less bearish positioning.
The borrow picture complicates the short thesis in a specific way. Availability has tightened dramatically — from above 180% for most of June to just 61% by June 30. That shift in a week means the lending pool is being used up fast; roughly one share is now available for every 1.6 already borrowed, compared to nearly two available for every one borrowed a week ago. The 52-week minimum availability hit 0%, so the pool has been fully exhausted before. Cost to borrow, while still low in absolute terms at 0.72%, has risen 54% over the week — a directional signal that the incremental share to borrow is getting harder to source. If availability continues tightening at this pace, the cost to borrow can reprice quickly. For now the borrow remains easy money; the risk is if the stock moves against shorts and a covering wave hits a thinning pool.
Options traders, by contrast, are relaxed. The put/call ratio of 0.20 is exactly in line with its 20-day average, with a z-score essentially flat at zero — there is no incremental hedging demand from the options market at all. The 52-week PCR range spans 0.08 to 0.73, and the current print sits near the low end, meaning call volume dominates the options market. That divergence is worth naming plainly: short sellers are piling in, but options traders are not hedging defensively. The stock gained 10% on the week and 0.4% on the final day, suggesting some of that call activity may be momentum-driven upside bets rather than protective puts — a setup that can amplify moves in either direction.
The Street backdrop is mixed and the most recent analyst data is dated. The only action within the past year came in late April when Alliance Global Partners initiated with a Buy and an $8.00 target. Before that, the dominant theme through mid-2025 was a wave of downgrades — Citigroup, Keefe Bruyette, and Zelman all moved to Underperform or Sell ratings, most with targets well below $2. Targets have since been revised upward modestly (Citi lifted to $1.40, KBW to $2.00), though with OPEN trading at $4.62, those remain well below spot — suggesting the consensus remains skeptical even as the stock has reprinted considerably higher than most bears expected. The consensus mean target of $4.82 is close to current levels, but given the staleness of the dataset the Street's real-time view is unclear. What is clear is that factor scores paint a troubled picture: EPS momentum ranks in the 6th percentile over 30 days and the 2nd percentile over 90 days. The one exception is EPS surprise, which ranks in the 95th percentile — the company has consistently beaten reduced expectations, even while the business continues to lose money.
The earnings history underlines the downside sensitivity. The most recent Q1 print on May 7 produced a one-day drop of 8.2% and a five-day loss of 18.1%. The prior event in June showed almost no reaction. With the next print scheduled for August 6, the window between now and then is when positioning will matter most — the question is whether the rapid short build of the past two weeks proves prescient or becomes the fuel for a squeeze, particularly as availability narrows further.
