Modelled scale observations · equities

Equity execution study.

Across two eligible, overlapping starts on 24 and 25 June 2026, the model completed at least 97.8% of a CHF 5m-equivalent fresh entry and 92.9% of a CHF 10m-equivalent fresh entry over three sessions. Every difficult residual remained visible.

What was tested

Fresh entry into the frozen 18 June 2026 target: two overlapping starts on 24 and 25 June, three sessions and five one-hour slices per session. The base schedule uses 0.50% participation and a 75% haircut to causal forecast volume; the lower-volume view uses 0.25% and 50%. Fills are capped again by observed current-interval volume.

Completion is absolute frozen-weighted share completion. The weaker-side measure keeps long and short progress together, and unfilled names remain residuals. Cost is the worst modelled one-way basis-point charge on executed notional. CHF equivalents use the dated 30 June 2026 exchange-rate receipt. A separate raw-input recomputation checked reference prices, volume limits, completion, side balance and cost.

Limitations

Two overlapping starts are a small, dependent sample. These modelled scenarios do not set a maximum capacity or live-capital limit. Borrow and locates, spreads, depth, queue position, realised impact, financing and operating continuity remain unmeasured live inputs.
