Measured concentration

Read this figure with the following in mind

7.7% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 143.3

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

7.66% collateral

DFAS's filing lists 2,056 positions including 7.66% of net assets in securities-lending cash collateral. Counted as filed the fund reads 143.3 effective holdings with a top ten of 9.97%; on its own investments — the figure above — it reads 896.9 with a top ten of 2.54%. 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 DFAS's shares

2026-07-31

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-07-31, $1.3bn was out to 34 borrowers. The largest, National Financial Services LLC, held 23.4% of it.

BorrowerOn loanShare of the loan
National Financial Services LLC $315m 23.4%
HSBC BANK PLC $213m 15.8%
MORGAN STANLEY & CO LLC $121m 8.9%
Wells Fargo Bank, National Association $103m 7.7%
BofA Securities, Inc. $102m 7.5%

The filing reports no cash collateral position against this loan. Collateral taken in a form the fund does not hold as a position does not appear in N-PORT, so this is silence rather than absence.

Since the previous filing

2026-01-31 → 2026-04-30

2,081 positions became 2,116: 113 added (0.7% of the fund at the later date), 78 dropped (2.0% at the earlier date). Half the sum of all weight changes, a turnover proxy: 11.0%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

92.8% of DFAS is carried at a quoted market price (fair-value level 1); 0.0% at level 3, priced from the filer's own inputs. Categories and levels are the filer's, from Form N-PORT; what a low level-1 share does and does not mean is in the measure's page.

Derivative exposure and counterparties

as of 2026-04-30

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 $14.04B. Notional of an interest-rate or currency swap is not equity exposure.

  • Why 2,017 IWM Holdings Read as 33: Securities Lending in the Russell 2000 ETF

    IWM, the iShares Russell 2000 ETF, files 2,017 holdings but our concentration measure read it as 33. The cause is a 17% cash-collateral position from securities lending, flagged in the filing itself; set it aside and the fund's own investments behave like about 840. Seventy-three funds on this site, including IJH, IJR, RSP, LQD and HYG, had the same problem. What we found, what we changed today, and what is still open.
