AST SpaceMobile has delivered its most significant change in short positioning in months, with bears covering at scale following the August 10 earnings release — yet the stock, at $71.52, is still down 3.8% from its post-earnings highs, and the structural short trade is far from finished.
The headline shift is in short interest itself, which had been stubbornly frozen through weeks of pre-earnings tension. SI has dropped to 56.6 million shares — 20.4% of free float — down from 63.2 million the week prior and 70 million at the start of July. That is an 11.6% decline in a single week, the largest weekly reduction in the series. For the first time since prior notes began tracking this name, the covering is real: this is not new supply entering the pool, it is bears exiting. The monthly decline of 17.2% confirms the trend predates this week, but the acceleration is new. Days to cover remains near 3.3 per the most recent FINRA data, still elevated but easing.
The borrow market tells a story of transition rather than resolution. Availability has climbed to 12.3% — the same level it touched briefly before earnings, and still tight by any historical standard. Two days this week it hit 100% utilisation (availability near zero) before pulling back, reflecting the choppiness of a borrow pool in flux. Cost to borrow has actually drifted lower to 1.22%, down 6% on the week, though still 36% above where it was a month ago. The ORTEX short score has slipped to 69.9 from 70.3, a small but directional move. Availability remains well inside the 20–27% range that characterised June — the pool is looser, but far from open. Options are not adding much signal here: the put/call ratio of 0.47 is only modestly above its 20-day mean of 0.45, nowhere near the 52-week high of 0.67, suggesting options traders have not dramatically re-priced the post-earnings setup in either direction.
The Street reaction to earnings was mixed in direction but revealing in its details. Analysts responded to the print within hours. Cantor Fitzgerald raised its target to $90 from $80 while holding Overweight. Piper Sandler trimmed to $98 from $100, also staying Overweight. UBS shaved its Neutral target to $78 from $80. The net effect: the consensus mean target is $78.48, a 9.7% premium to Thursday's close, and the analyst recommendation differential ranks in the 96th percentile of the universe — the Street is more constructive on this name than almost any other. The bull case centres on FCF growth potential, direct-to-device broadband economics, and government-sector optionality. The bear case focuses on satellite deployment delays, spectrum interference from Starlink, and the sequential FCF burn that remains deeply negative. EPS surprise ranks in the 90th percentile, suggesting the print itself landed better than feared — which likely explains why the covering accelerated post-release.
The earnings history adds one data point worth noting. The August 10 release produced a day-one move of just -0.43%, remarkably muted given the stock's prior volatility and the weight of short positioning heading in. The August 11 session produced an 8.1% move — suggesting the initial reaction understated the market's eventual read. That two-session pattern, where the real move came the day after the print, is consistent with a setup where short covering and reassessment of the long thesis happened on a lag rather than instantly.
Institutional ownership adds context to the covering picture. Rakuten Investment Management, the largest reported holder at 5.2% of shares, cut its position by 15.6 million shares in the most recent filing period — a reduction larger than any single week's SI move. BlackRock added 756,000 shares. Vanguard entities collectively hold over 8% and appear to have been net buyers. Strategic holders including Alphabet and AT&T remain static. The insider register is uniformly negative: CEO Abel Avellan sold 2.5 million shares at $58.68 in June, the CFO and CTO also sold in that period. The 90-day net insider value across all trades is a net-positive figure by shares count but is entirely composed of sales at prices between $58 and $127 — suggesting planned distribution, not accumulation.
The next scheduled earnings event is November 10. Between now and then, the story is whether SI continues its descent from 20.4% toward the 15% range that would represent a more normal elevated-growth-company short base — or whether the bears who remain conclude the post-earnings relief rally at $71 is the exit opportunity they need. Cantor's $90 target and the Street's broadly Overweight skew sit above the current price; how quickly the borrow pool normalises and whether availability can sustain above 10% without collapsing again will frame the next chapter for ASTS.
