¿Qué es Centre book, factor overlay?

También llamado: centre book · factor overlay

Definition 3.8 The Desk and the Firm · Capítulo 3 — The Multi-Manager Platform

A platform’s centre book is the book the centre trades itself with the fund’s capital, alongside the pods: to hedge exposures the pods share, to add to positions many pods hold, or to trade its own strategies. A factor overlay is a centre-book position that offsets the sum of the pods’ exposures to a common factor, so that the fund keeps the pods’ specific returns without their shared risk.

The chapter’s platform over twenty years (seed 1), gross of fees, with and without a centre-book overlay that hedges the pods’ summed exposure to their one shared factor. The overlay keeps the mean and removes the shared swings. Data: fm_platform.sim, firm.podshop.overlay.
