BITO holdings

BITO reports 5 holdings and behaves like 1.2 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 17 quarters of filings.

Measured concentration

as of 2026-05-31

This figure is not comparable with other funds

filed long positions cover only 69.7% of net assets, so a concentration figure computed from them describes a fraction of the fund rather than the fund

93.1% 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.

Computed by this site from the fund's SEC Form N-PORT filing; what the measure does not tell you · every fund in one table · hold it with other funds? X-ray the mix. Pricing: 93.08% at a quoted market price (level 1), one issuer country.

What stands out

as of 2026-05-31

The largest line in BITO's filing is not a stock but ProShares Genius Money Market ETF, a fund position at 64.83% of net assets.

Each sentence is read from the fund's own SEC filing; the class median is computed across the comparable unknown funds on this site. Nothing here is a view on the fund.

Since the previous filing

2026-02-28 → 2026-05-31

2 positions became 2: 0 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: 0.7%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of BITO compared this way, as a feed: changes.xml · all funds: filings received.

93.08% unknown, 6.92% repurchase agreement as filed; 93.1% 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 2026-05-31

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 $1.70B. Notional of an interest-rate or currency swap is not equity exposure.
