Crowding: Risk and Opportunity
We established a systematic approach to analyzing the high conviction ideas of money managers through their 13F filings. We used this approach to inform recommendations about position sizing, and sometimes whether we would even buy or short a stock. While 13F filing data are lagged, and we do not know any manager’s real exposure as we are not assessing the options market or any short positions, we found it instructive to define a proprietary universe of fundamental managers, define high conviction, and use our quantitative models to improve our ability to find superior and inferior groups of equities.
