AST SpaceMobile closed Thursday up 10% to $58.44 — yet short interest barely moved, and the borrow market remains among the tightest it has been all year, leaving the stock coiled ahead of its August 10 earnings event.
The week's most meaningful shift is in the borrow pool, not the position itself. Availability has loosened from its 52-week low of 0.3% — recorded just last Thursday — to 3.2% by July 30. That is still extraordinarily tight: roughly three shares remain available for every hundred already borrowed. The context matters here. Two weeks ago availability was at 24%, then it collapsed through zero during the peak of short-interest accumulation. The partial reopening this week is consistent with the covering that has taken SI down to 63.3 million shares, 22.8% of the free float, from a peak of 68.3 million on July 21. But the 7% weekly reduction in shares short has not translated into a structurally more open lending market — availability remains well below the 20–27% range that characterised most of June. Cost to borrow eased 19% on the week to 1.17%, though it is still running 5% above last month. The ORTEX short score held at 70.3, down only fractionally from 70.6 at the peak, and the factor scores tell the same story: utilization ranks in the bottom 1% of the universe, days-to-cover in the bottom 20%. Nothing in the lending data suggests the bears have capitulated — they have trimmed modestly from a very high base.
Options positioning is the counterpoint. Bulls outnumber hedgers by a wide margin: the put/call ratio of 0.45 is below its 20-day average of 0.47 and running near the softer end of its 52-week range (high 0.67, low 0.32). The z-score of -0.86 is mildly call-skewed — not a screaming directional signal, but consistent with a contingent of holders expecting either an earnings-driven re-rating or a short-squeeze dynamic to materialise. The divergence between the borrow market and the options market has been a recurring feature of this name all month. It has not yet resolved.
The Street's posture shifted this week. Scotiabank upgraded to Sector Perform on July 29, the first positive rating action from a neutral-leaning firm in the recent cycle. B. Riley moved to Buy on July 17, and Piper Sandler initiated at Overweight with a $100 target on July 16 — the most bullish new entry in the analyst stack in months. Those moves partly explain Thursday's 10% session. Set against that: the consensus remains a Hold, one underperform rating is still outstanding (Barclays, Underweight, $65 target), and the mean price target of $80.48 implies roughly 38% upside to the current price. The EV/EBITDA multiple has compressed sharply, down from its 30-day high; the P/B at 10.97x reflects the market's willingness to pay for the satellite broadband option rather than underlying book value. Bulls point to the direct-to-phone IP portfolio and 202% revenue growth; bears note persistent operating losses, a Piotroski F-score of just 3, and Starlink's structural head start.
The insider picture remains a headwind to the bull narrative. CEO Abel Avellan sold 2.5 million shares on June 22 at $58.68 — a $146.7 million transaction — marking the largest single insider sale in the recent history captured here. The CFO, CTO, COO, and President all sold in late May and June at prices between $93 and $126. Net insider disposals over the 90-day window total roughly $449 million in value. Those sales were executed at meaningfully higher prices than where the stock trades today, which cuts both ways: it reflects prior optimism that has since been tested, but the cluster of C-suite selling at the prior highs adds weight to the bear case that internal holders viewed those levels as stretched.
Peer satellites tracked a similar direction on the day. IRDM gained 7.4% and TSAT added 8.8% on July 30, suggesting the move was at least partly sector-driven rather than company-specific. Both are down or flat on the week, however, mirroring ASTS's own -1.3% weekly result despite the single-session pop. The key variable to watch into August 10 is whether availability remains above 2% — a further tightening back toward zero would signal that covering has stalled and existing shorts are being rolled rather than closed ahead of the print.
