RT Journal Article SR Electronic T1 Creating Dynamic Pretrade Models: Beyond the Black Box JF The Journal of Trading FD Institutional Investor Journals SP 41 OP 48 DO 10.3905/jot.2018.13.4.041 VO 13 IS 4 A1 Robert Kissell YR 2018 UL https://pm-research.com/content/13/4/41.abstract AB We provide a framework for investment managers to create dynamic pretrade models. The approach helps market participants shed light on vendor black-box models that often do not provide any transparency into the model’s functional form or working mechanics. In addition, this allows portfolio managers to create consensus estimates based on their own expectations, such as forecasted liquidity and volatility, and to incorporate firm proprietary alpha estimates into the solution. These techniques allow managers to reduce overdependency on any one black-box model, incorporate costs into the stock selection and portfolio optimization phase of the investment cycle, and perform “what-if” and sensitivity analyses without the risk of information leakage to any outside party or vendor.TOPICS: Portfolio construction, statistical methods
