Profile & Investment Philosophy

Joel Greenblatt continues to deploy his systematic value strategy via Gotham Asset Management. In Q1 2026, the portfolio remained anchored by the S&P 500 (SPY) and the Gotham Enhanced 500 ETF (GSPY), while maintaining high-quality tech exposure in Apple and NVIDIA. Greenblatt's process-driven approach aims to extract alpha from the market's emotional cycles through rigorous quantitative screening.

Track Record

Joel Greenblatt ran Gotham Capital from 1985 to 1994 with a reported annualized return of roughly 50% gross before returning outside capital, one of the most aggressive records in modern investing. He then continued to compound personal and partner capital privately and later launched Gotham Asset Management with Robert Goldstein, running long-short and long-only strategies based on his quantitative value framework. Gotham Asset Management today manages billions of dollars across mutual funds and separate accounts. The Magic Formula methodology described in The Little Book That Beats the Market has been replicated and stress-tested extensively in academic literature.

Signature Trades

Marriott Spinoff: Host Marriott (1993)
When Marriott split into asset-heavy Host Marriott and asset-light Marriott International in 1993, institutional holders dumped Host because it carried the real estate and the debt. Greenblatt bought Host aggressively, recognising a classic Greenblatt-style forced-seller spinoff. Host rerated sharply over the following years as the real estate cycle turned, becoming the case study in You Can Be a Stock Market Genius and the canonical example of mispriced spinoffs.
Wells Fargo / Berkshire Warrants (1993)
Greenblatt has cited his use of LEAPS and warrants on quality franchises in the early 1990s, particularly around Wells Fargo, as a way to generate Gotham's outsized returns with controlled downside. By buying long-dated options on businesses he already believed were undervalued, he turned a high-conviction value bet into an asymmetric payoff. The trade illustrates a side of Greenblatt often forgotten: he is not just a Magic Formula screener, he uses derivatives surgically when structure allows.
Magic Formula Live Track Record
The publication of The Little Book That Beats the Market in 2005 turned Greenblatt's combination of high earnings yield and high return on capital into a public formula. He then ran live Magic Formula accounts at Gotham, demonstrating that the system worked in production despite long periods of underperformance versus the S&P 500. The Magic Formula's transparency and out-of-sample resilience made it one of the most studied factor strategies in modern quant value research.

Current Strategy (2026)

Gotham Asset Management's 2026 13F is the opposite of Pabrai or Hohn: roughly 1700 holdings spread across the US market, with SPY itself at about 17.9% as the largest single line. The portfolio is effectively a quant value tilt around a core S&P 500 exposure, generated by Gotham's earnings-yield and return-on-capital ranking models. Position sizes are small, turnover is meaningful but disciplined, and the long book is paired with short exposure in the firm's hedge-fund vehicles. This is a deliberately industrialised version of the Magic Formula: thousands of small bets aggregating into a structural factor exposure, not the single high-conviction call style of the early Gotham era.

BMI

BMI Counter-Take

Greenblatt is two managers in one biography: the 50% gross compounder running concentrated spinoffs and derivatives until 1994, and the systematic factor manager running 1700-name portfolios today. The Magic Formula remains intellectually clean and academically validated, but its real edge has narrowed as quant value has been commoditised. We respect the durability and the willingness to publish the playbook, which most managers would never do. For retail the takeaway is not to copy SPY at 17.9%, it is to internalise the framework: rank by quality and price, ignore stories, and accept that a great system can lag the index for years.
