Warren Buffett in the context of "Bill "

Berkshire Hathaway Inc. (/ˈbɜːrkʃər/) is an American multinational conglomerate holding company headquartered in Omaha, Nebraska. Originally a textile manufacturer, the company transitioned into a conglomerate starting in 1965 under the management of chairman and CEO Warren Buffett and vice chairman Charlie Munger (from 1978 to 2023). Greg Abel now oversees most of the company's investments and has been named as Buffett's successor. Buffett personally owns 38.4% of the Class A voting shares of Berkshire Hathaway, representing a 15.1% overall economic interest in the company.

The company is often compared to an investment fund; between 1965, when Buffett gained control of the company, and 2023, the company's shareholder returns amounted to a compound annual growth rate (CAGR) of 19.8% compared to a 10.2% CAGR for the S&P 500. However, in the 10 years ending in 2023, Berkshire Hathaway produced a CAGR of 11.8% for shareholders, compared to a 12.0% CAGR for the S&P 500. From 1965 to 2023, the stock price had negative performance in only eleven years. In August 2024, Berkshire Hathaway became the eighth U.S. public company and the first non-technology company to be valued at over $1 trillion on the list of public corporations by market capitalization.

The Wharton School (/ˈhwɔːrtən/ WHOR-tən) is the business school of the University of Pennsylvania, a private Ivy League research university in Philadelphia. Established in 1881 through a donation from Joseph Wharton, a co-founder of Bethlehem Steel, the Wharton School is the world's oldest collegiate business school. It is one of six Ivy League business schools, and is the business school which has produced the highest number of billionaires in America, including Warren Buffett, Elon Musk, and U.S. President Donald Trump.

The Wharton School awards undergraduate and graduate degrees with a school-specific economics major and concentrations in over 18 disciplines in Wharton's academic departments. The undergraduate degree is a general business degree focused on core business skills. At the graduate level, the Master of Business Administration program can be pursued by itself or along with dual studies leading to a joint degree from its law, engineering, and government schools.

An index fund is a mutual fund or exchange-traded fund (ETF) designed to follow certain preset rules so that it can replicate the performance of a specified basket of underlying securities (most often a stock market index or a bond market index).

The main advantage of index funds for investors is that they are difficult to outperform consistently. Academic research has consistently found that most active investors (stock pickers) within a given market segment underperform the relevant index after fees and taxes. Investors also do not need to spend time analyzing various stocks or stock portfolios. Thus investors, academicians, and authors such as Warren Buffett, John C. Bogle, Jack Brennan, Paul Samuelson, Burton Malkiel, David Swensen, Benjamin Graham, Gene Fama, William J. Bernstein, and Andrew Tobias have long been strong proponents of index funds.

The Gates Foundation is an American private foundation founded by Bill Gates and Melinda French Gates. Based in Seattle, Washington, it was launched in 2000 and is reported to be the third-wealthiest charitable foundation in the world, holding $77.2 billion in assets as of December 31, 2024. The primary stated goals of the foundation are to enhance healthcare and reduce extreme poverty across the world, and to expand educational opportunities and access to information technology in the US. Key individuals of the foundation include Warren Buffett, chief executive officer Mark Suzman, and Michael Larson.

The scale of the foundation and the way it seeks to apply business techniques to giving makes it one of the leaders in venture philanthropy, though the foundation itself notes that the philanthropic role has limitations. In 2007, its founders were ranked as the second most generous philanthropists in the U.S., behind Warren Buffett. As of 2018, Bill Gates and Melinda French Gates had donated around $36 billion to the foundation. Since its founding, the foundation has endowed and supported a broad range of social, health, and education developments, including the establishment of the Gates Cambridge Scholarships at Cambridge University.
