SumZero is an investment website for professional investors (collectively referred to as the "buyside"), and buyside professionals are granted membership per an application, where they must be on the research team at a hedge fund, mutual fund, private equity fund, or investment banking proprietary trading desk. Its exclusivity is said to mirror that of Facebook at its outset, and though it currently has over 10,000 buyside members and over 40,000 'Basic' users, roughly 75% of buyside applicants for membership are rejected.
The site's co-founder and current CEO Divya Narendra came up with the idea for SumZero in April 2007, while working for the hedge fund Sowood Capital in Boston. Narendra and college friend Aalap Mahadevia subsequently launched SumZero in March 2008.
In October 2012 the site announced its first Annual Investing Challenge, jointly organized by SumZero and the Value Investing Congress. The top 3 ideas were pitched on the CNBC television show Fast Money and winner Ryan Fusaro presented his investment idea at the Value Investing Congress on October 1, 2012 alongside the portfolio managers Bill Ackman, David Einhorn, and Barry Rosentein.
A paper by Wesley Gray of Drexel University, Bryan Johnson of Creighton University, and Rice University’s Steven Crawford and Richard A. Price III, "Do Buy-Side Recommendations Have Investment Value?”, analyzes a subset of SumZero’s Idea database, which is composed of 2,135 long and short calls on U.S. equity securities submitted to the website by 1,112 buyside analysts from 910 different funds.
This study shows that short recommendations from these analysts generate an immediate and significant decline in price, and long recommendations have positive short-term returns and exhibit a positive drift. The collective evidence presented in the paper suggests that buy-side recommendations have investment value. The paper also documents that broad institutional ownership decreases significantly for buy-side recommendations, but increases for the buy-side analysts’ employers, suggesting there is a wealth transfer between the broader institutional market and buy-side firms in the sample.
