Risk Simulation

Scenario & Stress Testing

Pragmatic stress testing on your current holdings: apply historical shock windows, view worst-day and cumulative drawdowns, compare against VaR/ES, and surface limit breaches — with exports suitable for governance review.

Core stress views

These map directly to what Hedgtrade already produces in the risk workflow (stress file, multiples vs VaR, breach list). Keep it simple: see the drawdown, see it vs VaR, see if anything breaks limits.

Historical Stress (Amplified)

Apply historical shock windows to the portfolio to estimate drawdown under past-like conditions. Use amplifiers to sanity-check severity (e.g., 1× baseline vs higher stress).

Practical outputs: scenario rows per date/window; portfolio PnL impact.

Stress vs VaR

Compare stress results against VaR bands to contextualize whether a shock is “within expectations” or meaningfully outside the normal risk envelope.

Practical outputs: multiples / ratios; quick “is this bigger than VaR?” view.

Limits & Breaches

Surface any limits breached by the stress runs (portfolio-level and key concentration / exposure checks), so review meetings focus on decisions, not data wrangling.

Practical outputs: breach list; what exceeded; by how much.
