Turn independent strategy systems into one portfolio decision process

PDS sits above individual strategy engines. It evaluates providers, separates research credibility from portfolio usefulness, manages integration, forms portfolio-level decisions, and monitors whether each role remains justified. The current Core combines ADAA and Forecast-to-Rank Allocation (F2R) as complementary providers, while PDS handles portfolio integration, adaptive risk control, and monitoring at the system level.

Three operating layers

PDS Core, Adaptive Risk Control, and Dynamic FX

PDS separates the source of portfolio opportunity from the controls applied around it. PDS Core is the main multi-strategy portfolio. PDS Adaptive is a bounded hybrid risk-control layer that can reduce total Core exposure when its defensive controller is active. Dynamic FX manages USD/KRW hedge exposure on a separate monthly decision clock.

Core portfolio

PDS Core

Combines admitted strategy providers under a defined portfolio policy while preserving each provider's timing, identity, and research record.

Adaptive risk control

PDS Adaptive

PDS Adaptive uses an RL signal inside a bounded hybrid controller with independent point-in-time volatility confirmation. It does not select securities or replace the Core allocation engines.

FX implementation

Dynamic FX Overlay

Applies a monthly USD/KRW hedge decision and cost schedule while keeping the underlying USD portfolio decision separate.

The frozen controller was trained under the previous Core parent definition and is currently applied to the revised Core without automatic retraining. Historical prior-parent results are therefore not a current-Core Adaptive track record. Current Adaptive state and risk budget remain visible in the public dashboard; low-level controller settings, seeds, and model artifacts remain internal.
Decision architecture

From independent providers to one portfolio decision

01
Strategy / Forecast Providers

Independent strategy systems enter through defined interfaces and keep their own research and operating records.

02
Common Representation

Provider outputs are translated into a consistent portfolio representation before cross-strategy comparison.

03
Research Review

Data timing, research quality, implementation assumptions, and operational readiness are reviewed before portfolio use.

04
Portfolio Admission

A sound research result does not automatically enter the portfolio; incremental portfolio usefulness is assessed separately.

05
Portfolio Integration

Approved providers are combined under a defined strategic allocation policy while each provider's identity and contribution remain traceable.

06
Adaptive Risk Control

A bounded hybrid Adaptive layer can selectively reduce Core risk without replacing the underlying strategy engines.

07
Monitoring / Refresh

Core, Adaptive, Preview, Dynamic FX, and provider states are refreshed and monitored under a common operating clock.

Research review & portfolio admission

Research quality and portfolio usefulness are evaluated separately

PDS keeps research review separate from portfolio admission. A strategy can be well specified as research yet add little incremental portfolio value, while a useful portfolio role does not change the status of a failed or inconclusive research result. Admission therefore depends on both research quality and the role the strategy adds to the portfolio.

Research review

Is the strategy result credible?

Data timing, reproducibility, model specification, robustness, and result quality are assessed on their own terms.

Portfolio admission

Does it add a useful portfolio role?

Incremental diversification, role fit, operational burden, and interaction with existing providers determine whether the strategy belongs in the portfolio.

Current Active Core providers

Complementary strategy systems inside the PDS portfolio process

ADAA and F2R are the strategy systems currently admitted to the Active Core. Each remains an independent Portfolio Strategy System with its own models, research record, and operating history; PDS is responsible for portfolio-level admission, integration, the current combined decision, and monitoring.

Portfolio Strategy System

ADAA

A multi-asset strategy built around Decision Diversification, combining complementary decision horizons, opportunity views, defensive responses, and persistence.

Forecast-to-Rank Allocation (F2R)

Live Completed Performance

Updated with each canonical PDS release. The cumulative chart compares PDS Core + Dynamic FX with PDS Core over their common history beginning in May 2017. The longer current-definition Core / Dynamic FX reconstruction begins in December 2005 and remains available in the full dashboard. The second chart shows the latest 12 completed holding months for Core + Dynamic FX and Adaptive + Dynamic FX. Adaptive begins in May 2021. Current MTD is excluded throughout.

Adaptive history note: Adaptive begins in May 2021. Observations through 2026-08-31 are certified historical evidence under the prior Core parent definition; later observations are forward monitoring of the same frozen controller without retraining. The cutoff is a provenance boundary, not the end of the performance series. Standalone ADAA and F2R histories remain separate.
Operations & monitoring

One operating clock, with private infrastructure kept out of the public view

The public dashboard uses the same decision state, clocks, and portfolio data as the operating system. It omits machine-specific infrastructure and private controls rather than maintaining a separate investment view. Current decision state, Adaptive state, Preview, portfolio weights, Dynamic FX monitoring, and performance follow the same data and clock conventions.

On-demand refresh. The release workflow refreshes provider state, checks cross-system consistency, and rebuilds the public dashboard from the current system state.
Provider separation. ADAA and F2R remain independent systems connected to PDS through defined interfaces rather than copied into PDS.
Release checks. Release checks cover data consistency, clocks, identity, responsive layout, and private-environment boundaries before deployment.
Public and internal detail

Public operating views, private implementation

Public

  • System architecture, provider relationships, and governance
  • Current PDS Core, Adaptive, Preview, Portfolio, Performance, and Dynamic FX operating views
  • Current decision clock and detailed portfolio targets through the PDS dashboard
  • Historical performance views with support periods and evidence boundaries stated explicitly

Internal implementation

  • Local filesystem paths, runtime/cache details, repository controls, credentials, and debug tooling
