LUNR shorts climb as the stock loses a quarter of its value in a month

LUNR enters the week of October 21 with a sharp disconnect at its core: short interest at a multi-month high, an overwhelmingly bullish analyst consensus, and a stock that has shed 24% in a single month.

The short-side pressure is the dominant story. Short interest has climbed to 32% of the free float, up roughly 6.6% over the past month and continuing to tick higher through October. That is a genuinely elevated level for a mid-cap aerospace name, and the trend has been consistently upward since early September. Borrow costs, however, tell a different story: the cost to borrow has actually fallen about 22% over the past month to under 0.8%, which is low for a stock with this much short interest. Availability has tightened meaningfully this week, dropping from around 46% to 35%, meaning roughly one share is available to borrow for every three already lent out. The 52-week low on availability reached 0.35%, so there is still room to tighten further. Options positioning is not adding urgency to the bear case: the put/call ratio at 0.32 is fractionally below its 20-day average of 0.34, well short of the 52-week high of 0.67 hit in late September. Call volume continues to dominate, which sits in contrast to the heavy short interest.

The Street remains stubbornly constructive despite the price decline. Nine analysts carry a buy or equivalent rating, with a mean price target of $29, implying more than 175% upside from the current price of $10.54. The most recent analyst action came from Macquarie last week, when Marni Lysaght initiated coverage with an Outperform rating and a $25 target. That makes Macquarie's initiation notable: it is a fresh, well-timed entry that adds a new voice to an already bullish chorus at a point when the stock is down sharply from levels where most targets were set. The one dissenting voice of scale is B of A Securities, which carries an Underperform with a $13 target. The bull case rests on lunar infrastructure spending, the Lanteris acquisition, and a Q4 gross profit improvement that showed 1,150% year-over-year growth. Bears point to recurring operating losses, an EBITDA loss of $19.1 million on $44.8 million in revenue, and the risk of a slowdown in the lunar programs that drive demand. Factor scores underline the tension: EPS surprise ranks in the 97th percentile and 90-day EPS momentum ranks 99th, yet the short score rank sits at just 3rd percentile, among the most bearish readings in the universe. That combination of strong estimate-beat history alongside extreme short positioning is the central puzzle of this note.

The ownership register adds another layer of complexity. Kamal Ghaffarian, the company's co-founder, holds a 13D activist position with a disclosed stake of 19.7%, unchanged in the most recent filing from July. A 13D registration means the SEC has recorded activist intent, and that is one of the more newsworthy facts on this stock's register. The disclosure caveat applies: stakes are as-last-filed around the 5% threshold, and the 13D reflects Ghaffarian's position as of early July. That said, his open-market activity in September consisted of option exercises and same-day sales under a pre-arranged 10b5-1 plan, all at prices between $14 and $16, well above current levels. The net insider position over 90 days registers as a large negative in share terms, though most of that reflects the exercise-and-sell mechanics of compensation plans rather than discretionary conviction selling. BlackRock added 2.2 million shares in the quarter to September 30, and State Street added 1.97 million, suggesting some passive and institutional buying even as the stock fell.

The peer group has been broadly weak, which provides context without excusing the underperformance. RKLB dropped 21% on the week, SATL fell 19%, and RCAT lost 13%. LUNR at down 13% for the week sits in the middle of that range, not the worst performer but not spared. The sector is clearly under broad pressure.

Earnings are scheduled for November 13, and the two most recent prints produced single-day moves of 12% and 6% to the upside. With the next report 23 days out, the key question is whether the short interest that has been building through October holds, compresses ahead of results, or pushes tighter as availability continues to shrink toward levels seen at the 52-week low.
