Who holds it

SEC 13F · LATEST QUARTER PER FUND
None of the 15 tracked funds disclose SION in their latest 13F. The funds we follow.

13F filings cover US-listed holdings and arrive up to 45 days after quarter end, so positions may have changed since.

Stakes of 5% or more

SCHEDULE 13D/A · filed Sep 21 · investment · EDGAR ↗

A 13D means the holder crossed 5% with intent beyond passive ownership and had to state a purpose; a 13G is the passive version. Every new 13D on tracked companies.
