Across its top 20 institutional holders, ASTS's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 21/100, avg. turnover score 43/100).
ASTS ranks #683 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
ASTS is a disclosed holding of Ken Griffin (Citadel Advisors LLC), one of the tracked superinvestors on AlphaSMO — it makes up 0.1% of that fund's own 13F portfolio.
ASTS is a top-conviction position for Vodafone Ventures Ltd — at 100.0% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in ASTS belongs to Susquehanna International Group, LLP, but the position matters far more to Vodafone Ventures Ltd, who has 100.0% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.
CX Institutional has added to its ASTS position for two straight quarters, increasing it by $31.0K to reach $33.0K today.
Salvus Wealth Management, LLC has trimmed its ASTS position for two straight quarters, cutting it by $2.2M while still holding $4.2M.
ASTS is down 8.5% today, but institutions show net buying of $5.1B this quarter — a divergence between today's price move and the underlying institutional flow.
ASTS reported a net loss of $618.8M over the trailing twelve months.

Top 5 Institutional Movers
ASTS does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
