The simple explanation

For the matching rows, compared with Q1 2026, the Q2 2026 report's stock rows show 1 new position, 9 positions with more shares reported, 10 positions with fewer shares reported, and 5 positions that no longer appear.

Green + ▲ means new or more shares; red + ▼ means fewer shares or no longer listed. The words and dot count repeat the meaning without relying on colour. Fewer shares or no listing does not mean the manager opened a short position.

13F reports can arrive up to 45 days after quarter-end, so this comparison is not proof of when, why, or at what price the manager traded.

What changed since the prior report

Green means the manager reported a new or larger share amount. Red means a smaller amount or the stock was no longer listed. This compares two delayed reports; it does not show the exact trade.

Sources and exact comparison rules

Biggest reported changes — ranked by position value. The bar is the position's size against the largest one shown; the figure under it is the difference in the filed SH or principal amount. Corporate actions are not normalized.

Absent from latest filing — a 13F reports only that the position is absent, not when, why, or for what proceeds it changed. The prior SH or principal amount is printed, but these rows are not ranked because those units are not comparable.
