Boaz Weinstein

Boaz Ronald Weinstein (born 1973) is an American hedge fund manager and founder of Saba Capital Management. He rose to prominence at Deutsche Bank in the early and mid 2000s with his credit default swap and capital structure arbitrage trading strategies. He then formed a proprietary trading group within Deutsche Bank. After leaving the bank in 2009, Weinstein started Saba Capital Management as a separate hedge fund. As of August 2025, Saba manages $6 billion in assets.

Weinstein was among the first to identify and publicize a trading opportunity that was later nicknamed the "London Whale", when a trader at JPMorgan made a number of trades that exposed the firm to about $6.2 billion in losses. The trades in turn netted several hedge funds including Weinstein's hundreds of millions of dollars after they took an opposing position in the credit default swap market. His father owned an insurance brokerage and his mother, who had immigrated from Israel, was a translator. He has an older sister, Ilana. At the age of sixteen, he was ranked as a Life Master by the United States Chess Federation and was third in the US for his age group.

Weinstein had an interest in investing from an early age and was a fan of the television program Wall Street Week, hosted by Louis Rukeyser, which his family watched every Friday night. As a junior at the Stuyvesant High School in New York City, he was a winner of a stock-picking contest sponsored by Newsday, beating out a field of about 5000 students. At 15 years old, he began working as an intern at Merrill Lynch, after school and during the summer. Saba reportedly lost as much as $1.8 billion in 2008, Weinstein's only losing year out of his eleven years at Deutsche Bank. By January 2009, it had regained about $600 million. He had left Deutsche Bank two months before, and his former employer had agreed to the move years in advance and to become one of Saba's main brokers. Weinstein was also included in Fortune's 40 Under 40 list in 2010 and 2011.

Weinstein profited from the 2012 JPMorgan Chase trading loss. The trader, Bruno Iksil, was selling billions of dollars' worth of notes for the Investment Grade Series 9 10-year Index CDS. Weinstein's gains for Saba's clients were estimated between $200 million and $300 million and Saba's assets under management reached a new high of $5.6 billion. In 2012, he funded renovation work at his alma mater, of Stuyvesant High School.

In May 2020, the Weinsteins donated a total of $2 million to about a dozen nonprofit organizations fighting domestic violence during the COVID-19 pandemic, including Sakhi for South Asian Women, American-Jew Family Support Center, Womankind and Violence Intervention Program.

Political views Weinstein is a strong supporter of the State of Israel though critical of the government of Benjamin Netanyahu. He rejects the notion of Israel as a colonizer. Following the October 7 attacks, Weinstein was a signatory to the "Asset Manager Community Statement of Support for Israel." This public pledge condemned Hamas, affirmed Israel’s right to self-defense, and committed to supporting Jewish and Israeli employees. However, in signing, the asset managers (including Weinstein) also pledged not to hire anyone involved in Pro-Palestinian protests in the aftermath of the October 7 attacks

Personal life Weinstein is a skilled poker and blackjack player. He had become interested in blackjack since the early 1990s and learned card counting after reading Edward O. Thorp's Beat the Dealer. He often played with a secretive blackjack team from MIT which has been profiled in the book Bringing Down the House, later adapted into the film 21.

In 2010, Weinstein married Tali Farhadian in Manhattan. His former wife is a Democrat who served in the Obama Department of Justice and ran for Manhattan District Attorney in 2021. The former couple share three daughters.

In 2012, Weinstein bought a $25.5 million property on Manhattan's Fifth Avenue, from the estate of Huguette Clark.
