AI agent for portfolio managers

Portfolio Concentration Stress Agent

Find hidden concentration, test it under stress and propose trims that actually reduce it.

Portfolio Concentration Stress Agent: what goes in, what the agent does and what you get

What it does

A portfolio can hold twenty different names that all drop together when rates jump or one sector stumbles. This agent reads holdings and finds hidden correlation by factor and sector, such as several stocks that share an exposure to rates or a single supplier. It runs stress cases, such as a rate shock, an oil drop or a credit spread widening, and shows the loss. It proposes trims or swaps that reduce the concentration, then reruns the stress to confirm the risk fell and that no new concentration appeared. If the risk did not fall enough, it tries a larger trim or a different holding. The manager approves any trade before it goes to the desk.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

It compares stress losses with risk limits and proposes the smallest trim that brings the loss within limit without creating a new concentration.

  • Flag a cluster when correlation is above 0.7 over 1 year
  • Treat a stress loss above 5 percent of NAV as a breach
  • Prefer trims of the most liquid names first
  • Reject trades that create a position above the single name limit

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Stress scenarios
  • Loss limit (default 5 percent of NAV)
  • Correlation cutoff (default 0.7)
  • Position limits

What keeps you in control

It always asks you first

  • Manager approves every trade before it goes to the desk

Hard limits

  • Never places trades
  • Shows model limits and data dates in every report

It stops when

  • Done: stress losses within limits or manager has accepted the breach
  • Stop: price data missing for key holdings

An example run

What happensA rate shock of 100 basis points showed a 6.2 percent loss against a 5 percent limit. Six names in utilities and REITs moved together. The agent proposed trimming 3 percent of NAV. The rerun gave 5.3 percent, still over, so the check failed. A larger trim to 5 percent brought the loss to 4.8 without a new concentration. The manager approved the trades.
