Flirting with Models

Flirting with Models explores the design and management of systematic investment strategies through conversations with their practitioners. Corey Hoffstein asks how an idea becomes a portfolio, including the data, constraints, implementation decisions, and sources of risk involved. Subjects span trend following, factors, derivatives, portfolio construction, and quantitative research. The discussions assume some investment knowledge and reward listeners who want to understand strategy mechanics rather than simply collect market opinions.

The Desk’s listening note

Pause when an implementation detail is unfamiliar; the distinction between an attractive backtest and a workable portfolio is often the point.

Who it’s for

Investment professionals, quantitative researchers, and advanced individual investors who want detailed discussions of how systematic strategies are designed, combined, and implemented in practice.

A useful place to start

Pick an interview on a strategy you already understand, such as trend following or equity factors, then use unfamiliar terms as a focused research list.
