The book is divided into two parts: Circuit Design and System Design. The first part
deals with everything that goes directly inside the main code, while the second deals
with units that might be located in a library (for code sharing, reuse, and partitioning).
Current investment management practice typically assumes that
the OE portfolio is deﬁned by the fund manager’s investment “style.”
Roughly, style refers to a subset of the investment universe in which a
manager is constrained to operate, such as small capitalization stocks
versus large stocks, or “value” versus “growth” ﬁrms. The style con-
straint may be a self-declared specialization, or it may be imposed
on the manager by the ﬁrm.
