D. E. Shaw & Co., L.P. is a multinational investment management firm founded in 1988 by David E. Shaw and based in New York City. The company is known for developing complicated mathematical models and computer programs to exploit anomalies in financial markets.^[5] As of December 1, 2023^[update], D. E. Shaw has $60 billion in assets under management, including alternative investments and long strategies.^[6]

The company was founded by David E. Shaw, a former Columbia University computer science professor with a PhD from Stanford University.^[7] D. E. Shaw began investing in June 1989, having secured $28 million in capital from Donald Sussman's Paloma Partners and several private investors.^[8] The company carefully protected its proprietary trading algorithms. Many of its early employees were scientists, mathematicians, and computer programmers.

In 1994, the company's net return was 26 percent. It managed several hundred million dollars in "market-neutral strategies, including statistical arbitrage, Japanese warrant arbitrage, convertible-bond arbitrage and fixed-income trading."^[9] Its non-hedge fund activities in the mid-90s included setting up a broker-dealer subsidiary, founding the email provider Juno Online Services, launching an online banking and brokerage firm, and opening an office in India focused on developing software and systems to support the company's trading operations and online businesses.^[8]

In 1997, the firm returned capital to most of its early investors in favor of a structured credit facility of nearly $2 billion from Bank of America, with terms that allowed D. E. Shaw & Co. to keep a higher fraction of profits than hedge fund investors normally allow.^[10] In effect, Bank of America provided an infusion of $1.4 billion to D. E. Shaw, hoping to benefit from the latter's investment expertise.^[11] One year later, Russia defaulted on its debt, resulting in large losses for D. E. Shaw's fixed-income portfolio.^[12] As a result, Bank of America lost $570 million due to its investment in D. E. Shaw, and paid out an additional $490 million to settle associated shareholder lawsuits.^[11]

Following the collapse of this alliance, D. E. Shaw laid off employees, reducing its workforce from 540 employees in 1999 to 180. The company's capital shrank from $1.7 billion to $460 million.^[9]

David E. Shaw directed the company from 1988 to 2001. In 2002, he removed himself from day-to-day involvement in order to focus on D. E. Shaw Research and transitioned leadership of day-to-day activities to a team of six of the firm's senior managing directors.^[13] The same six-member Executive Committee of Anne Dinning, Julius Gaudio, Louis Salkind, Stuart Steckler, Max Stone, and Eric Wepsic remained intact until 2012 when Steckler retired.^[14]

At the beginning of the financial crisis in August 2007, D. E. Shaw's multi-strategy fund had assets of $20 billion. A third of the fund's exposure was to the equity markets and equity-linked quantitative strategies. As a result, the fund lost five percent of its assets and had its worst-performing month to that point in time. By September 2008, the company's capital was four times leveraged. In the final months of 2008, gains on its then $15 billion multi-strategy funds were lost.^[9]

Twenty percent of the company's assets under management were in its credit strategies and were the hardest hit during the financial crisis.^[9]

To avoid further loss of portfolio value and asset fire sales, D. E. Shaw temporarily halted withdrawal of funds. By 2009, D. E. Shaw had returned about $2 billion at clients' requests.^[9] One year later, the Financial Times reported that investors estimated the company had honored an additional $7 billion in client redemption requests.^[7]

D. E. Shaw's total assets under management fell from a high of $34 billion in 2007 to $21 billion in 2010.^[5] The company had 1,300 employees, a reduction of 10% of its workforce.^[7]

In September 2019, D. E. Shaw required all of its employees to sign non-compete agreements, which was common among asset management companies but not previously required at the firm. This was not received favorably by some employees.^[15]

In 2023, D. E. Shaw was charged with a penalty of $10 million by the SEC for having its employees sign confidentiality disclosure agreements from 2011-2023, without including whistleblowing rights.^[16][17]

The company manages a variety of investment funds that make extensive use of quantitative methods and proprietary computational technology to support fundamental research.^[7][18][19] The company also uses qualitative analysis to make private equity investments in technology, wind power, real estate, financial services firms, and distressed company financing.^[9] D. E. Shaw & Co. has also provided private equity capital to technology-related business ventures. Examples include Juno Online Services, an Internet access provider, and Farsight, an online financial services platform that was acquired by Merrill Lynch.^[20][21]

The company had $40 billion in aggregate capital^[22][23] and $15.6 billion in hedge fund AUM as of 2011. As of June 1, 2021, the company more than tripled in size with $55 billion in AUM, $35 billion of which are alternative investments and the remaining $20 billion long investments.^[24] It was ranked as the 21st-largest hedge fund by Institutional Investor in 2011.^[22] By 2020, D. E. Shaw & Co. was ranked as the 10th-largest hedge fund globally by discretionary AUM.^[25]

In 2004, a subsidiary of one of the company's funds acquired the toy store FAO Schwarz after it had filed for bankruptcy.^[26] FAO Schwarz reopened for business in New York and Las Vegas in the fall of 2004. In the same year, D. E. Shaw affiliate Laminar Portfolios acquired the online assets of KB Toys, which continued operating as eToys.com.^[27]

In 2006, the Financial Times reported the firm's involvement as a potential financing and investment partner for Penn National Gaming (the casino and racetrack company) as an example of the breadth of Wall Street firms' involvement in the "private equity boom," describing D. E. Shaw as "a hedge fund group."^[28] The financing was required as Penn National Gaming had a market value of $3.3 billion (2006) and $1.4 billion in annual revenues and wanted to acquire Harrah's Entertainment, a company with a market value of $14.7 billion (2006) and at that time the largest US casino operator.^[29]

In late 2009, the Financial Times reported that D. E. Shaw & Co. had set up a portfolio acquisitions unit, the aim of which was to acquire illiquid assets from rival hedge funds, during the financial crisis.^[30]

D. E. Shaw entered the Indian market in 2006,^[31] with Anil Chawla, then the CEO of GE-Commercial finance, India & South East Asia, as the Country Manager. The India operations were initially headquartered in Hyderabad, Telangana. D. E. Shaw entered into several large private equity deals in the country. This included a joint-venture with India's largest private sector company, Reliance Industries, to provide financial services.^[32][33] Other investments included real estate company DLF Assets Limited and publishing group Amar Ujala Publications, which were subject to Indian regulatory scrutiny and legal disputes.^[34][35] Chawla left his position with D. E. Shaw in 2012.

D. E. Shaw scaled back its private equity activities in India after 2013.^[36]

Currently, the Executive Committee comprises Anne Dinning, Max Stone, Eric Wepsic, Eddie Fishman, Alexis Halaby, and Edwin Jager.^[37] The firm has 2,500 employees.^[6]

In 2007, David Shaw sold a 20 percent stake to Lehman Brothers as part of a broader strategy to diversify his personal holdings;^[38] D. E. Shaw had $30 billion of assets under management in 2007.^[39] At the time of its bankruptcy in September 2008, Lehman Brothers' holdings in D. E. Shaw & Co. remained intact.^[40]

In 2015, Hillspire, the family office of Google chairman Eric Schmidt, acquired the 20 percent passive ownership stake in D. E. Shaw & Co. from the bankruptcy estate of Lehman Brothers Holdings Inc.^[41]

D. E. Shaw supports educational programs such as the American Regions Mathematics League,^[42] United States of America Mathematical Olympiad, the International Mathematical Olympiad, Mathematical Olympiad Program, and The Center for Excellence in Education.^[43]

The firm has offices in the United States, India, China, Singapore, England, Luxembourg, and Bermuda.^{[citation needed]}

In 2022, D. E. Shaw was ordered to pay $52 million to a former employee after a defamation lawsuit.^[44]
