The Low-Minus-High Portfolio and the Factor Zoo
Abstract
Regardless of whether the CAPM is rejected for valid reasons or by mistake, a single long-short portfolio will always explain, together with the market, 100% of the cross- sectional variation in returns. Yet, this portfolio, which we coin the “Low-Minus-High (LMH) portfolio,” need not proxy for fundamental risk. We show theoretically how factors based on valuation ratios (e.g, book-to-market), or on investment rates, can be proxies for the LMH portfolio. More generally, the empiricist can uncover an infinity of proxies for the LMH portfolio, thus unleashing the factor zoo.Competition Links and Stock Returns
Abstract
We consider a firm’s competitiveness based on the manner by which other firms mention it on their 10-K filings. Using all public firm filings simultaneously, we implement a PageRank-type algorithm to produce a dynamic measure of firm competitiveness, denoted C-Rank. A high-minus-low C-Rank portfolio yields 16% alpha annually, where return predictability mainly stems from cross-sector competitiveness. The findings are largely consistent with investor underreaction to firm business opportunities identified by other strong firms. Nevertheless, stock return covariation with the C-Rank portfolio spread suggests that part of the return predictability can be interpreted as compensation for systematic cross-sector disruption risk.Discussant(s)
