What changed this quarter

    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: +$33.5M. The current book reports 2,733,926 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.

    2,733,926 current shares − 156,250 prior shares on the same basis = +2,577,676 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.
