The portfolio data platform that keeps your history honest.
Store, maintain, share and analyse holdings and performance over time — backed by a complete, auditable record that rolls forward day by day. For live funds, model portfolios, research sleeves and benchmarks alike.
Portfolio data lives everywhere — and agrees nowhere.
Holdings scatter across spreadsheets, custodian files and internal tools — with no authoritative history.
Manual daily and monthly updates are slow, error-prone and almost impossible to audit.
Performance numbers disagree depending on which file or model was used last.
Benchmark comparison is a separate exercise, disconnected from the portfolio itself.
Sharing portfolio history means exporting fragile snapshots that go stale immediately.
Research and operations work from different versions of the same truth.
Treat portfolio data as a living product — not a static file.
Define portfolios, load holdings and returns as dated snapshots, and Portfolio Exchange maintains a complete historical record that rolls forward day by day.
From that single source of truth, measure performance, compare against benchmarks, understand what drove returns, and share read-only views — all traceable back to dated inputs.
Write once as dated commits. Read forever as daily history.
The top-level container for a strategy or account — base currency, profile, managers, owner. Live, model, research or benchmark.
Parallel views within a portfolio — a live track, a backtest, a benchmark sleeve — each with its own history and health.
Dated records — holdings, NAV, total return, allocations. Tied to an effective date and to whoever created them. Nothing is overwritten.
The day-by-day picture built from commits and market data — holdings, valuations, returns and analytics for every calendar day in scope.
Six pillars, one source of truth.
Portfolio & branch management
Create and maintain portfolios and branches at scale. Define strategy, currency, managers and ownership. Archive or restore as strategies wind down.
Historical holdings & returns
Load holdings by weight or quantity for any effective date. Batch-backfill years of history. Maintain a full timeline, not just the latest positions file.
Daily maintenance & roll-forward
Once committed, history stays current automatically — refreshing holdings, returns and allocations as new inputs arrive. No repetitive recalculation.
Benchmarking
Compare branches to default or custom benchmarks — simulated paper portfolios or real market references. Alpha, tracking error and capture, built in.
Performance analytics & attribution
Institutional-grade insight — risk, return, rolling metrics and attribution by sector, industry and geography. Understand not just what returned, but why.
Sharing & collaboration
Multi-user access with ownership and manager assignment. Share read-only history with clients or partners — collaboration without losing control.
Understand not just what returned — but why.
Know when a number is ready — and when it isn’t.
Portfolio Exchange surfaces a clear health state across every branch, instrument and day. Coverage and quality of underlying prices and FX are checked before numbers reach a report or a client.
Holdings and returns reconcile. Safe to publish and share.
Usable, but a proxy or gap needs review before formal reporting.
Missing prices or breaks. Numbers should not be trusted yet.
