You can access EDHEC-Risk Institute research paper "Factor Investing in Liability-­Driven and Goal­-Based Investment Solutions", published in May 2020.

The main objective of this paper is precisely to contribute to the acceptance of factor investing by providing useful pedagogical clarification with respect to the benefits of factor investing within the liability-driven investing paradigm.

To this end, authors draw an important distinction between the benefits of factor investing in the performance-seeking portfolio and its benefits in the liability-hedging portfolio. We also argue that adopting a factor investing lens offers new useful insights with respect to the improvement of the interaction between performance-seeking and liability-hedging portfolios. Overall, the paper can be regarded as a first step towards the introduction of a comprehensive investment framework blending liability-driven and factor investing, widely recognized as the two most significant advances in institutional money management over the last two decades

Insigful results relayed in the Edito "How Factor Investing Can Help Liability-Driven Investors" published in the May 2020 edition of EDHEC-Risk Institute quarterly newsletter.
