Backtesting parameters for portfolio strategies involving QBTS require clarification on key variables. Implementation details such as universe scope (e.g., U.S. equities), ranking methodology (e.g., prior-day volume), weighting schemes (e.g., equal-weighted), and transaction cost assumptions remain open for specification. These factors will determine the accuracy of historical performance simulations.

To execute the back-test accurately, the following details must be confirmed: 1) Universe selection (e.g., NYSE/NASDAQ-listed stocks), 2) Ranking rules (e.g., prior-day volume vs. same-day execution), 3) Portfolio weighting (e.g., equal-weighted), and 4) Transaction cost inclusion. Default settings assume U.S. equities, prior-day volume ranking, equal-weighted allocations, and zero explicit costs unless otherwise specified.
