How to read this table
This table shows the institution’s holdings reported to the SEC for the selected quarter and changes compared with the previous quarter.
- Security / CUSIP
- The security’s ticker symbol, such as AAPL, alongside its CUSIP, a unique security identifier. If no ticker is available, the security may be identified by its CUSIP only.
- Class / Position
- The security type or share class as stated in the filing, such as common stock (COM) or a specific class of shares.
- Shares / Units
- The number of shares or units the institution reported holding.
- Value (USD)
- The total value of the position in US dollars as of the reporting date.
- Weight
- The position’s share of the total reported holdings value. For example, a 12.55% weight means AAPL accounts for approximately 12.55% of that reported value.
- Share change
- The change in the number of shares compared with the previous quarter. A plus sign (+) indicates an increase; a minus sign (−) indicates a decrease.
- Change %
- The percentage change in the number of shares compared with the previous quarter. For example, +52.25% means the reported share count increased by approximately 52.25%.
- Reported activity
- Increased: the reported quantity rose. Reduced: it fell. Unchanged: it stayed the same. Newly reported: the position appears in the current filing but not in the previous one. No longer reported: it appeared in the previous filing but not in the current one.
Important: These changes compare quantities reported in filings; they do not necessarily document the exact timing of purchases or sales. In particular, “Newly reported” does not necessarily mean the security was purchased during that quarter.
Source: FMP Ultimate / SEC Form 13F. Report as of 2026-06-30; filed 2026-08-14. Changes compare reported quantities, not confirmed transactions. “Newly reported” and “No longer reported” do not establish exact purchase or sale dates. 13F covers reportable securities, not the institution’s total assets under management.
