Security Analysis: An Investment Perspective Kewei Hou∗ Haitao Mo† Chen Xue‡ Lu Zhang§ Ohio State and CAFR LSU U. of Cincinnati Ohio State and NBER March 2020¶ Abstract The investment CAPM, in which expected returns vary cross-sectionally with invest- ment, profitability, and expected growth, is a good start to understanding Graham and Dodd’s (1934) Security Analysis within efficient markets. Empirically, the q5 model goes a long way toward explaining prominent equity strategies rooted in security anal- ysis, including Frankel and Lee’s (1998) intrinsic-to-market value, Piotroski’s (2000) fundamental score, Greenblatt’s (2005) “magic formula,” Asness, Frazzini, and Peder- sen’s (2019) quality-minus-junk, Buffett’s Berkshire Hathaway, Bartram and Grinblatt’s (2018) agnostic analysis, and Penman and Zhu’s (2014, 2018) expected return strategies. ∗Fisher College of Business, The Ohio State University, 820 Fisher Hall, 2100 Neil Avenue, Columbus OH 43210; and China Academy of Financial Research (CAFR).
