NBIS Shorts Hold Firm as $151 Stock Faces Its Earnings Test

Nebius Group fell 11% over the past week to close at $151.64, a steeper drop than the median peer decline of roughly 5%, yet short sellers added nothing and covered nothing: the position that has defined this tape for months remains exactly where it was.

Short interest at 22.2% of free float, backed by 47.6 million FINRA-confirmed shares short as of October 15, is the number that matters most on NBIS right now. What is striking is not the level but the behaviour. The short base has not moved through a 38% drawdown from September highs. It did not cover into the bounce to $170 last Tuesday, and it did not add into Tuesday's 7.2% recovery to end the week. The ORTEX short score of 68.7 places the stock in the bottom 6th percentile of the universe, ranking 6th for short positioning intensity. That score has been almost perfectly flat for two weeks, moving in a range of 68.2 to 68.8: a base in stasis, not a base that is about to shift.

The borrow market is now tighter than it was a week ago, though still far from the extremes seen earlier in the year. Availability has fallen to 43.5%, down 29% over the past week, meaning roughly two shares are available for every three already borrowed. That compares with a 52-week low of 0.63%, when the lending pool was effectively exhausted, and a 52-week high of 100%. Cost to borrow at 0.61% is negligible, down 6% on the week: shorts face no meaningful carry pressure, which helps explain why they are not being forced to cover. Options positioning is neutral rather than defensive, with the put/call ratio at 0.93, barely above its 20-day average of 0.91 and well below its 52-week high of 1.30. The setup is unusually calm for a stock eight days from a major earnings release.

The Street is split in a way that reflects genuine disagreement about what Nebius actually is. The mean analyst price target of $281 sits 85% above the current price, with initiations from Rosenblatt at $304 and Truist at $355 pulling the average up, while Piper Sandler cut its target from $237 to $185 on October 21, the most recent move, keeping a Neutral rating. Rothschild initiated with a Sell and a target of $84. The bull case is straightforward: 454% year-over-year revenue growth in Q2, an exit ARR of $3 billion, GPUs more than four times oversubscribed, and a $17 billion Microsoft agreement anchoring backlog. The bear case is equally clear: free cash flow of negative $3.4 billion last quarter, net property and equipment that more than doubled in nine months to $13 billion, dependence on NVIDIA supply, and management's own acknowledgement that some neocloud financing sources are temporarily closed. EPS momentum factor scores rank in the 90th and 93rd percentiles over 30 and 90 days respectively, while the analyst recommendation differential ranks at the 100th percentile, meaning the gap between the most bullish and most bearish analysts is wider than almost any other stock in the universe.

NVIDIA's disclosed 9.3% stake via Schedule 13G, filed in July, is probably the most structurally significant ownership fact on the register. Goldman Sachs holds 4.7% but has trimmed from a prior 10.5%, per a 13G/A filed October 7. CEO-level insider activity in the data is dominated by Director Arne Grimme, who has bought roughly 1,500 shares across ten consecutive sessions from October 19 to October 29 under a pre-arranged 10b5-1 plan, all at prices between $154 and $170. These are small planned purchases rather than discretionary conviction trades, so they carry limited signal on their own. The 90-day insider net across all insiders is negative $140.7 million in value, reflecting earlier selling that dwarfs Grimme's accumulation.

The last time NBIS reported, the stock moved 32% the following day and held a further 16% gain over the subsequent five sessions. The print before that produced a 21% single-day decline. The range of outcomes following this company's earnings is wide. What to watch on November 12 is whether management's framing of the neocloud financing pause has tightened or eased since the CEO's comments, and whether the short base finally moves in response to whatever the numbers say.
