Your stake and evidence for MRCY
What it means for you
This public view does not read your holdings or watchlist; open the member view to check your stake.
Use this to decide what to research, rather than as an instruction to copy a trade.
What happened
A position newly appears in the Q2 2026 book.
Displayed change: +$59.5M. The current book reports 486,064 shares.
Why it can matter
A change between quarter-end disclosures can prompt a question about the manager's exposure. It does not reveal the trade date, the execution price or why the position changed; a full exit is not proof of a bearish decision.
How we got this
A new position uses its current quarter's reported dollar value; this is not the amount spent buying it.
Comparable books exclude identified CUSIP, share-basis and new-security events from trades. Exit-size bands describe prior book weight, not the manager's intent.

What happened

What was sold out, by size
- 2 small, between 0.015% and 0.25%
All of this comes from the filer's public SEC filings. A 13-F shows long positions in US-listed securities at quarter end and can leave out short positions, cash and non-US holdings, so it is not the whole portfolio. This is filing data, not investment advice.
