Portfolio decisions without spreadsheets: a PortView field note

Consider a multi-asset family office – principals, multiple mandates, holdings spread across public markets, private positions, and illiquid commitments. For years, allocation decisions ran on the familiar rhythm: a quarterly spreadsheet, painstakingly assembled, debated in a meeting, and stale within weeks. Every rebalance optimised roughly one thing at a time, and the interactions between return targets, liquidity needs, and concentration limits lived in the principal's head.

PortView, one of quaStrat™'s representative deployments, reframes this as a live optimisation problem rather than a periodic reporting exercise. The allocation question – how to deploy capital across conflicting objectives of return, risk, liquidity, concentration, and mandate constraints – is formulated once and solved continuously as positions and conditions move.

What changes in the boardroom is the nature of the conversation. Instead of arguing about whose spreadsheet assumptions are right, the principals interrogate a recommendation that already holds the trade-offs together and shows its reasoning. The binding constraints are visible: this allocation is capped here by a liquidity floor, there by a concentration limit, elsewhere by a mandate. The debate moves from arithmetic to trade-off.

Figures shown in any live PortView preview are illustrative. Each engagement is custom-fit to the client's mandate, holdings, and tax position.
