Quant Portfolio Construction

Run deterministic long-only portfolio construction across minimum variance, risk parity and mean-variance candidates.

Version: v2

Stability: stable

Sandbox: Available

Production: Entitlement required

Target latency: ≤ 1,200 ms

POST/api/v2/investment/portfolios/{portfolio}/construct

Uses provider-backed return history, FinanceGPT portfolio algorithms and the MathPHP-backed Quant Kernel. No orders are transmitted.

Required scope: investment:run

Try it in the FinanceGPT sandbox

The playground uses deterministic isolated sandbox fixtures. It never queries production workspace data and does not require you to paste an API secret into the browser.
