SDS holdings

SDS reports 10 holdings and behaves like 2 equally weighted ones, computed from its SEC Form N-PORT filing for 2026-05-31. The fact sheet publishes the first number; this page computes the second, and traces it across 27 quarters of filings.

Measured concentration

as of 2026-05-31

This figure is not comparable with other funds

swap and futures notional is 196% of net assets: the fund's exposure is delivered by derivatives, and a count of its filed positions does not describe it. See the exposure section for what the notional is written on

69.7% of net assets carries no asset category in the filing

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.

6 positions became 7: 5 added (26.0% of the fund at the later date), 4 dropped (34.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 45.0%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Derivative exposure and counterparties

as of 2026-05-31

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 $433M. Notional of an interest-rate or currency swap is not equity exposure.
