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.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| 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%.

How it has done
