AllianceBernstein LP. Values in this filing are at the previous quarter end's prices; its share count is the quarter end's.

Q2 2026 looks like a 10-for-1 split: most managers that listed it in both quarters show the same change in shares. Additions and reductions this quarter are not read as buying or selling.

Managers listing KLAC in Q2 2026

Share of 13F value is the position’s reported value over everything the manager reported that quarter. The share change is against Q1 2026, and only where both filings list the position. A rise in value with no rise in shares is the price, not buying.

Largest increases and reductions, by shares

Q1 2026 to Q2 2026, among managers that listed it in both quarters or opened it.

A split quarter: the share changes are the split, so no one is ranked as buying or selling.

New positions and exits

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

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.
28 in Q3 2024 to 28 in Q2 2026

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.
