NIO heads into its May 21 first-quarter results with the market's short-term posture shifting decisively bullish — shorts are covering, options traders are leaning call-heavy, and the stock is up 3% on the week even as most Chinese EV peers struggle.
The short-selling picture tells the clearest story this week. Short interest has fallen roughly 7.6% over the past seven days, dropping from around 143.5 million shares borrowed to 135.2 million. As a percentage of the free float, that puts shorts at 6.6% — still a meaningful level, but the direction of travel is unambiguous: positions are being unwound ahead of the print. The borrow market is tight, with availability at just 39.7% of outstanding short interest, meaning less than one share is available to borrow for every two-and-a-half already lent out. Cost to borrow, while still cheap in absolute terms at 0.68%, has climbed roughly 59% over the past month — a signal that demand for borrows has been rising even as the stock consolidates.
Options positioning reinforces the bullish lean. The put/call ratio has dropped to 0.70, the lowest reading of the past 52 weeks (the high was 0.80), and it sits more than two standard deviations below its 20-day average of 0.72. That is a strikingly call-heavy setup by NIO's own recent history. The combination of short covering and options buyers piling into calls points to a market that is actively repositioning for upside. NIO's ORTEX short score of 61.2 is elevated in absolute terms but has eased slightly from 62.4 a week ago, consistent with the incremental reduction in bearish pressure.
The Street is cautiously constructive, though the debate is firmly anchored to execution risk. The bull case rests on NIO's premium EV positioning in China, its battery-swap ecosystem, and roughly 326,000 units delivered in 2025. Bears counter that this represents only around 2% of the Chinese passenger NEV market and that new model launches have underdelivered early sales expectations. HSBC upgraded the stock to Buy in March, lifting its target to $6.80, which is broadly in line with where the shares trade today. Citigroup and Macquarie both trimmed targets last November, with Macquarie downgrading to Neutral. The key financial reference points: revenue is estimated at around $19.2 billion for the full year, with the company still loss-making at the net income line — reported EPS of -$0.22 — while EV/EBITDA runs at roughly 12x. The stock is cheap on an EV/revenue basis at 0.6x, but profitability remains the central question for any re-rating.
On the macro backdrop, a bill introduced in the US House of Representatives that would ban Chinese-made vehicles adds a layer of headline risk, though NIO's primary market exposure is domestic China rather than North American sales. Abu Dhabi holds a 16.7% stake — unchanged at the latest filing — while founder Bin Li controls 6.6%. BlackRock added 2.2 million shares in the most recent reporting period, bringing its holding to 3.1% of shares outstanding. The EPS surprise factor score ranks in the 97th percentile, the highest available reading, suggesting NIO has been a consistent upside beater against consensus — a useful data point given the timing.
The most recent earnings reaction, from the March 10 release, saw the stock jump 10.7% on the day and extend to a 20.6% gain over the following week. The release before that, in late February, produced a 7.3% one-day drop. NIO's post-earnings moves have been wide in both directions, and with availability tight and options skewed toward calls at a 52-week extreme, the May 21 print is shaping up as the week's pivotal event for the stock.
