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

2Overlap with other funds
2Measured against every other fund on this site, from the same filings. Combined effective holdings is how the pair behaves held in equal size.
| With | Overlap | Shared | Combined effective |

As filed, collateral included
1.17% collateralSOXX'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.

Returns the fund reported
2019-07 – 2026-06Monthly total returns from Item B.5 of SOXX's own filings, 84 months on record. Not computed here and not from a price feed.
Cross-checked against a series computed separately from prices: median difference 0.06 percentage points over 84 months, which is roughly the distributions. Every month with the filing it came from: SOXX.json · all funds.
Who borrows SOXX's shares
2026-06-30The 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.
| Borrower | On loan | Share 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 → 2026-06-3031 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.

Asset categories and pricing
as of 2026-06-3098.75% 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 2026-06-30A 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.

SOXL Holdings: What the 3x Semiconductor ETF Actually Owns
SOXL's SEC filing lists 42 positions: 30 semiconductor stocks worth 57% of net assets, eight index swaps with a notional of $41 billion (243% of net assets), and 39% in Treasury money funds. The stocks and the swap notional add to exactly 300%. Here is what the 3x semiconductor ETF holds, where the leverage comes from, who the counterparties are, and why its holdings count cannot be read like SOXX's.
