Your stake and evidence for CUE
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
Reported shares increased between Q1 2026 and Q2 2026.
Displayed change: +$4.5M. The current book reports 370,682 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
For an added or trimmed position, subtract split-adjusted prior shares from current shares, then multiply by the current book's reported value per share; this is not the execution price.
370,682 current shares − 227,305.467 prior shares on the same basis = +143,376.533 shares.
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 was sold out, by size
- 7 small, between 0.015% and 0.25%
- 2 slivers under 0.015%, often rounding or client flows
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.
