Across its top 20 institutional holders, HYLN's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 11/100, avg. turnover score 40/100).
HYLN ranks #3382 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
HYLN is a disclosed holding of David Shaw (D. E. Shaw & Co.), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.
HYLN is a top-conviction position for General Electric Co — at 7.8% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in HYLN belongs to BlackRock, Inc., but the position matters far more to General Electric Co, who has 7.8% 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.
Concurrent Investment Advisors, LLC has added to its HYLN position for two straight quarters, increasing it by $45.6K to reach $64.5K today.
HYLN is up 1.9% today, and institutions have been net buyers of $69.6M this quarter — today's price move and the underlying institutional flow are pointing the same direction.
HYLN reported a net loss of $52.2M over the trailing twelve months.

Q2 2026
Top 5 Institutional Movers
HYLN 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.
