Largest increases and reductions, by shares

There is no earlier quarter on file to compare with.

Increases

Reductions

No reduction among listed positions.

New positions and exits

At least these many: a manager is shown exiting only where its own filing shows the position gone.

New (28)

Exited (0)

No exit shown by a manager’s own filing.

Ownership over time

Every quarter on file. A quarter-end value moves with the price as well as with the shares held; buyers and sellers count comparable managers, by shares.

One quarter on file so far, so there is nothing to draw yet.

Holders over time, buyers and sellers, and the managers holding both, side by side for up to four stocks.

How much of the picture this is

A 13F is a manager’s long US-listed equity book at a quarter end, filed up to 45 days later. It shows no shorts, cash, bonds or performance, and it is never today’s portfolio. Large books are listed to their largest positions, so a manager missing from this table may still hold a small position below that line. These are 95 tracked managers, not the institutional market.
