What changed this quarter

  • BA

    BOEING CO

    +$173.2M

    New

    Your stake and evidence for BA

    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: +$173.2M. The current book reports 800,000 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.

    Where the data comes from

    SEC 13F quarter-end holdings for Q1 2026 and Q2 2026; these delayed disclosures omit shorts and many other assets.

    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: +$162.1M. The current book reports 5,000,000 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.

    5,000,000 current shares − 4,320,000 prior shares on the same basis = +680,000 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

  • 1 small, between 0.015% and 0.25%

Not counted as trades: SPCX (newly listed or spun off).

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.
