This case follows the protagonist, chief investment officer of a multifamily office, as she debates whether or not Venn, a factor-based portfolio attribution tool developed by quant manager Two Sigma, will be a beneficial tool for her firm. Using Venn, she starts looking into possible hedge fund investments in hope of both further diversifying her clients’ portfolios and hedging against a possible future downturn in markets. The case introduces the students to factor-based attribution analysis and helps them develop intuition for this technique using a manager selection decision in the context of a broader portfolio.
