Built for oversight, not speculation
Every feature in Sigilon Custody exists to answer one question before any other: how is capital protected today. Growth follows from discipline, not the reverse.
A system of checks, not a forecast engine
Sigilon Custody combines rules-based monitoring with AI-assisted pattern review to flag risk before it compounds. The system does not attempt to predict markets; it attempts to limit what a bad week can do to a portfolio.
Below is a detailed look at the core mechanisms families rely on when they choose oversight over guesswork. Each feature is described alongside the practical benefit it is meant to deliver.
Exit rules set before conviction clouds judgement
Position exits are defined in advance, tied to measurable thresholds rather than sentiment. When a threshold is reached, the position is reduced or closed — no committee debate, no waiting for a turnaround story.
- Removes emotion from the hardest decision in investing: when to stop a loss
- Thresholds are documented and reviewed, never adjusted mid-drawdown
- Consistent application across every holding, regardless of size
Each stage is logged with the data point that triggered movement to the next — a traceable record rather than a retrospective justification.
Allocation bands are reviewed on a fixed cadence, not reshuffled in response to headlines or short-term noise.
Concentration limits that hold under pressure
No single position, sector, or strategy is permitted to dominate a portfolio. Boundaries are set structurally, so a single bad decision cannot become a single catastrophic one.
- Caps exposure to any one holding regardless of recent performance
- Reserve allocation maintained for liquidity and optionality
- Rebalancing follows the schedule, not the mood of the market
Monitoring that does not stop at month-end
Portfolios are reviewed on a rolling basis rather than a single annual checkpoint. Conditions that matter — concentration drift, correlation changes, liquidity shifts — are tracked as they develop.
- Earlier visibility into drift from original allocation targets
- Reduces reliance on year-end surprises
- Review cadence is documented, not ad hoc
Each checkpoint produces a short note on positioning changes and the reasoning behind any adjustment, kept for later reference.
From signal to decision to record
Signal Detection
Pattern and threshold monitoring surfaces conditions that warrant attention — not predictions, but measurable deviations from set parameters.
Rule Application
Pre-defined exit, allocation, and concentration rules are applied consistently, removing the need for in-the-moment judgement calls.
Documented Outcome
Every action taken is logged with its trigger and timestamp, giving families a clear record of why a portfolio looks the way it does.
Applied across the situations families actually face
Sudden volatility spikes
When markets move sharply, pre-set thresholds act before a decision has to be made under pressure, limiting the extent of drawdown exposure.
A position grows beyond its original weight
Strong performers can quietly become oversized risks. Allocation boundaries flag and correct this drift on a fixed schedule rather than waiting for a crisis.
Multi-generational oversight handoff
Documented rules and review records make it easier for a portfolio's governing principles to be understood and continued by the next generation.
