Fund profile
As filed in the prospectus · 2026 Q2
The Defiance Quantum ETF (the Fund or the Quantum ETF) seeks to track the total return performance, before fees and expenses, of the BlueStar Quantum Computing and Machine Learning Index (the Index).
The fund tracks the BlueStar Quantum Computing and Machine Learning Index using a replication strategy, holding all or a representative sample of index constituents in the same proportions. The index includes globally-listed companies deriving at least 50% of revenue or operating activity from quantum computing or machine learning technology, screened semi-annually and rebalanced with equal weighting. The fund may diverge from the index when the sub-adviser uses representative sampling due to liquidity constraints, practical difficulties, or legal restrictions. Day-to-day investment decisions are delegated to a sub-adviser; the index provider is independent and unaffiliated with the fund's adviser, administrator, or distributor.
| Share class | Expense ratio |
|---|---|
| QTUM | 0.40% |
Portfolio turnover 42.00% · as of 2026 Q2
Allocation
Asset groups · long / short shown separately, never netted · 2026 Q2
| Stocks | 99.30% |
| Cash & short-term | 13.85% |
These positions come to 113.14% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.
Sector allocation
The same holdings as Allocation above, grouped by market sector instead of asset type · as of 2026 Q2
| Information Technology | 45.3% |
| International | 35.0% |
| Cash | 12.2% |
| Industrials | 4.6% |
| 3 smaller | 2.9% |
Government, Securitized and Cash are non-corporate buckets; International is foreign holdings we don’t sector-classify, and Other is the residual (held funds, unresolved names).

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
