PDT Partners: Platform Profile

Overview

PDT Partners is a New York quantitative investment manager whose roots date to Morgan Stanley's Process Driven Trading group, launched under Peter Muller in 1993. PDT became an independent firm in 2013.

Its current process centers on quantitative models, systematic research, rigorous testing and automated electronic trading across global markets.

May fit better for

• institutions seeking systematic quantitative hedge-fund exposure;
• investors comfortable with model-driven and automated trading;
• allocators seeking a mature quantitative research platform;
• qualified investors able to evaluate private pooled vehicles.

May fit less well for

• retail users seeking public self-service access;
• investors wanting discretionary stock-picking explanations for every position;
• users who infer the complete global book from U.S. 13F holdings;
• investors who treat historical testing as guaranteed future performance.

PDT is SEC registered

• Legal adviser: PDT Partners, LLC
• CRD: 163776

The wide gap between $19.2B RAUM and $1.904B of 13F securities is not evidence of an AUM collapse.

Assessment

PDT's Q2 13F is only a small visible slice of a $19.2B global quantitative platform. That is exactly what should be expected from a manager using automated trading across instruments and markets beyond ordinary 13F coverage.
