SOXX holdings

SOXX reports 32 holdings and behaves like 20.4 equally weighted ones, computed from its SEC Form N-PORT filing for 2026-06-30. The fact sheet publishes the first number; this page computes the second, and traces it across 28 quarters of filings.

Measured concentration

as of 2026-06-30

Read this figure with the following in mind

1.2% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 20.3

The figure below is what the filing says, published unchanged. What it may not do is sit beside a plain long-only fund and be read as the same quantity. How comparability is decided.

As filed, collateral included

1.17% collateral

SOXX's filing lists 33 positions including 1.17% of net assets in securities-lending cash collateral. Counted as filed the fund reads 20.3 effective holdings with a top ten of 61.65%; on its own investments — the figure above — it reads 20.4 with a top ten of 61.65%. The collateral is matched by a liability and is not a holding the fund chose; since 2026-09-18 every figure on this site sets it aside (methodology). Both numbers are in the data.

Who borrows SOXX's shares

2026-06-30

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $612m was out to 8 borrowers, 1.28% of net assets. The largest, JP MORGAN SECURITIES LLC, held 39.6% of it.

BorrowerOn loanShare of the loan
JP MORGAN SECURITIES LLC $243m 39.6%
CITIGROUP GLOBAL MARKETS INC. $174m 28.4%
BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED $100m 16.3%
STATE STREET BANK & TRUST COMPANY $25m 4.1%
HSBC BANK PLC $24m 3.9%

Cash collateral reported against the loan: 1.17% of net assets, 91.4% of the amount lent. That is a floor on the collateral, not the whole of it — collateral the fund does not hold as a position is not in this filing, so a figure under 100% is not evidence of under-collateralisation. How that figure behaves across all funds. Every quarter SOXX has filed, with each borrower: SOXX.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

31 positions became 32: 1 added (0.0% of the fund at the later date), 0 dropped (0.0% at the earlier date). Half the sum of all weight changes, a turnover proxy: 12.1%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

98.75% equity, 1.25% short-term investment as filed; 100.0% carried at a quoted market price (fair-value level 1). Categories and levels are the filer's; what a low level-1 share does and does not mean is in the measure's page.

Derivative exposure and counterparties

as of 2026-06-30

A position count cannot describe a fund that uses derivatives, because a swap is filed at its unrealised gain, not its exposure. These are the notionals the fund itself reported, against net assets of $47.82B. Notional of an interest-rate or currency swap is not equity exposure.
