Early life and education
Career in finance
In 1985, Greenblatt started a hedge fund, Gotham Capital, with $7 million, most of which was provided by junk-bond king Michael Milken. Through his firm Gotham Capital, Greenblatt presided over an annualized return of 40% from 1985 to 2006.
Value Investors Club
Greenblatt co-founded a website with John Petry called the Value Investors Club, where investors approved through an application process exchange value and special situation investment ideas. Membership is capped at 250 members and considered highly prestigious. A 2012 academic study showed that the recommendations of members do in fact appear to generate significant abnormal profits. The club awards $5000 bimonthly to members who provide the best advice.
Magic formula investing
His book The Little Book that Beats the Market introduced an investment strategy of "magic formula investing", which is a method for determining which stocks to buy: "cheap and good companies" with a high earnings yield and a high return on invested capital. His strategy is featured in The Guru Investor by John P. Reese.
In October 2009 he launched Formula Investing, an online money management firm that follows the investment strategy described in his New York Times bestselling book The Little Book That Beats the Market. Formula Investing is a money management firm that uses a proprietary stock-screening system and a disciplined approach to manage portfolios of value stocks. The firm offers its services to individual investors and institutions and to registered investment advisors, who can use Formula Investing as a sub-advisor.
Formula Investing uses a system that determines portfolio selections based on a combination of their relative cheapness and quality, as measured by earnings yield and return on capital. Formula Investing allows money to be managed in a disciplined manner that removes factors, like excess emotion and future projections, that often lead to bad investment results.
Greenblatt is also famous for his contributions to education in New York City. In 2002, he donated $2.5 million to P.S. 65Q, a public elementary school in the borough of Queens, whose students come largely from the neighborhood's South American and South Asian immigrant communities. This investment, equal to about $1,000 per student per year over five years, helped P.S. 65Q to go from a struggling school to an urban success story almost overnight. He continues to aid the school in Ozone Park currently as they have continued to rise. Recently the school and principal Rafael Morales received a progress report score of A, scoring 98 out of a possible 100 points.
In 2006, Greenblatt also helped start the Success Academy Charter Schools, then known as the Harlem Success Academy Charter School, an elementary school in the city's historically African-American neighborhood. He is also a board member of the Institute for Student Achievement, a national leader in developing new small high schools and transforming large comprehensive public high schools into small learning communities.
