INSTITUTIONAL RISK

Measure the risk in the portfolio you hold.

Aegis calculates VaR, CVaR, factor exposure, concentration and stress results as positions change. It also includes portfolio optimisation, regime analysis and multi-strategy sleeves.

Your book, priced now.

The same engine that runs on the homepage, against a real book rather than a demo basket. Every figure recomputes as positions change, and every one states its horizon and confidence.

A breach is surfaced on the panel, not in a nightly report.

Illustrative figures for a sample 42-position book. These are not live market data. The signed-in engine runs on your own holdings.

What it measures, precisely.

Every metric below states its method, because a VaR figure without its method, horizon and confidence is not comparable to anything.

Value at risk

Parametric, historical and seeded Monte-Carlo. 1-day and 10-day horizons at 95% and 99%.

Conditional VaR

Expected loss in the tail beyond VaR, not just the threshold you are unlikely to sit exactly on.

Risk contribution

Marginal contribution to volatility per name and component VaR. Sums to the portfolio figure exactly.

Factor decomposition

Market, momentum, quality, value and size exposures with the residual reported, not absorbed.

Concentration

Effective number of positions from 1/HHI, reported as a number rather than a verdict.

Liquidity

Days to liquidate at a participation cap, per name and for the book.

Tracking error

Ex-ante against your chosen benchmark, with the active share that drives it.

Fat tails

Skew, excess kurtosis and a Cornish-Fisher adjusted VaR where the normal assumption breaks.

Regime-conditional VaR

The same book priced under the regime the market is actually in.

Stress it against what actually happened.

Historical episodes and date-independent factor shocks, run on the current book. A dated replay is offered only when every holding traded through it; ineligible scenarios are withheld, never backfilled.

How a scenario is built
  1. Shock vector

    Each episode is stored as a factor return vector, so it applies to a book of any composition.

  2. Exposure map

    Current factor exposures are multiplied through the vector with residual risk handled separately.

  3. Eligibility check

    Dated episodes are gated on listing dates. Ineligible ones are labelled, never approximated.

An optimizer that respects the mandate.

An efficient frontier plus one-click allocations, each scored against the book you already hold. Constraints are hard, not preferences.

Many books, netted.

Sleeve portfolios net exposures across strategies and risk-budget between them, so the aggregate is a real number rather than the sum of separately flattering ones.

What Aegis is not.

Not an execution system

There is no order path. Aegis measures the book; it never sends anything anywhere.

Not an adviser

No recommendations or model portfolios sold as advice. It is measurement software.

Not a black box

Every figure states its method, horizon, confidence and as-of.
