Nebius Group has snapped back 20% in a week to $265.10, fully reversing the prior note's 15.5% selloff — yet the short base hasn't budged, borrow conditions have loosened materially, and the Chairman just trimmed into the strength.
The reversal is the sharpest development since the June 10 note flagged heavy shorts sitting tight through a dip. That picture hasn't changed structurally. Short interest is now at 20.7% of free float — fractionally higher than the 20.3% reported last week — meaning short sellers didn't cover on the way down and aren't covering on the way back up either. The position is sticky. What has changed is the borrow market. Availability has loosened to roughly 34% from readings that were below 15% for much of May, when the lending pool was close to fully exhausted. Cost to borrow has also eased back to 0.75%, down from highs above 1% earlier in the month. The practical read: there is more room in the lending pool now than at any point in the prior six weeks, which removes some of the mechanical squeeze pressure that existed when availability was at its tightest.
Options positioning is broadly neutral. The put/call ratio has edged up to 0.97, near its 20-day average of 0.95 and less than half a standard deviation above it. That's not a defensive extreme — the 52-week high on the PCR was 1.03, hit in early June when the stock was falling. Options traders are not rushing to hedge a rally that's already 20% in the books. The ORTEX short score of 69.3 has crept higher through the week but remains range-bound in the high 60s — consistent with a stock where the short side is large but not at a breaking point.
The Street is increasingly constructive but divided on target. B of A Securities raised its target to $280 on June 8, maintaining Buy, while Citi had already moved to $287 in mid-May. Both are now roughly in line with the current price. Against that, Morgan Stanley's Equal-Weight rating with a $144 target — raised from $126 in May — sits well below where the stock is trading, a notable outlier that reflects genuine fundamental disagreement. BNP Paribas initiated at Neutral with a $255 target in early June, and DA Davidson initiated separately at Neutral with a $250 target in mid-May, suggesting a cluster of newer coverage that sees fair value close to current levels but no clear upside catalyst. The mean target of $244 is now below the market price — an unusual configuration that flags the stock as having outrun consensus. The bull case centers on Nebius's vertically integrated AI cloud model and its multi-year Microsoft contract; the bear case points to hyperscaler competition, heavy capital requirements, and execution risk from a company still losing money at the operating level.
Institutional ownership adds one notable data point. Situational Awareness LP reported a full new position of 12.4 million shares — roughly 4.8% of shares — as of May 19, making it the second-largest named holder behind founder Arkady Volozh's 11.5% stake. That's a meaningful new buyer at the institutional level. BlackRock and State Street both added modestly through May. The insider flow, however, has moved the other direction again: Chairman John Boynton sold approximately 5,800 shares across multiple tranches on June 15, raising roughly $670,000 in aggregate into the very sessions that drove the weekly rally. The significance scores on each trade are low, and the size is modest relative to the $128 million in 90-day net selling the broader insider group has registered — but the direction is consistent.
With next earnings on July 28, the last print produced a 23% single-day gain on May 13. Shorts who held through that move and are still holding today face a setup where borrow has loosened but the position remains heavy, analysts near the stock's price are mostly neutral, and the Chairman is trimming into strength. How the lending pool behaves if the stock continues higher — and whether the short base finally shows any sign of covering — is the clearest dynamic to track into the summer print.
