Thomas Peterffy (born 1944) is a Hungarian-born American billionaire businessman. He is the founder, chairman, CEO, and the largest shareholder of Interactive Brokers. Peterffy worked as an architectural draftsman after emigrating to the United States, and later became a computer programmer. In 1977, Peterffy purchased a seat on the American Stock Exchange and played a role in developing the electronic trading of securities. According to Forbes he is the richest Hungarian, and the richest person in Florida.
Early life and career
Thomas Peterffy was born in Budapest, Hungary in 1944, in a hospital basement during a Russian air raid. He left his engineering studies and emigrated to the United States as a refugee in 1965. When he moved to New York City, he did not speak English. Peterffy began his career in the US as an architectural draftsman working on highway projects for an engineering firm. It was at this firm that he volunteered to program a newly-purchased computer, ultimately shaping the course of his future. Of his background in programming Peterffy said, "I think the way a CEO runs his company is a reflection of his background. Business is a collection of processes, and my job is to automate those processes so that they can be done with the greatest amount of efficiency."
Peterffy left his career designing financial modelling software and bought a seat on the American Stock Exchange to trade equity options. During his career in finance, he has consistently pushed to replace manual processes with more efficient automated ones. He would write code in his head during the trading day and then apply his ideas to computerized trading models after hours. Peterffy created a major stir among traders by introducing handheld computers onto the trading floor in the early 1980s. His business related to his AMEX seat eventually developed into Interactive Brokers.
Regulatory influence and political views
In 1999, Peterffy was influential in persuading the Securities and Exchange Commission (SEC) that US options markets could be linked electronically, which would ensure that investors receive the best possible options prices. He has also testified before the United States Senate Banking Subcommittee on Securities, Insurance, and Investment about adding banking regulations.
During the 2012 United States presidential campaign, Peterffy created political ads in support of the Republican Party. Peterffy bought millions of dollars of air time on networks such as CNN, CNBC, and Bloomberg. The ads consisted of a minute-long spot narrated by Peterffy that warned against creeping socialism in the United States. The ads were considered remarkable in part because Peterffy is not a candidate and did not buy the ads through a "527 group" but instead paid for them directly.
In the spot Peterffy said, "America's wealth comes from the efforts of people striving for success. Take away their incentive with badmouthing success and you take away the wealth that helps us take care of the needy. Yes, in socialism the rich will be poorer -- but the poor will also be poorer. People will lose interest in really working hard and creating jobs." Peterffy did not directly mention Republican presidential nominee Mitt Romney or Democratic President Barack Obama, but clearly favored the former.
Peterffy's ad received mixed responses. Joshua Green, writing for Bloomberg Businessweek, said "The ad, while slightly ridiculous, is deeply sincere and also quite affecting." Green also asked Peterffy whether the comparison between the United States and Hungary made in the ad was a fair one: "[Peterffy] couldn't really think that the U.S. was turning into socialist Hungary, could he? The government isn't suppressing speech and throwing political opponents in jail. No, he conceded, it wasn't. But it sure feels like that's the path we're on." Politico reported that the ad was "being hailed as one of the best spots this election cycle", and said that it could have been influential in Ohio due to its large Hungarian American population.
Voter registration records in Connecticut show that Peterffy is registered as an independent voter. Campaign contribution records show that he donated at least $60,000 to the Republican National Committee in 2011 and that over the past few years has mostly donated to Republican candidates.
Interactive Brokers Group, Inc. (IB) is an online discount brokerage firm in the United States. The company traces its origin to 1977 when Peterffy bought a seat on the American Stock Exchange as an individual market maker, and formed T.P. & Co. the following year. IB consists of many subsidiaries operating on most major stock, futures, bonds, forex, and options exchanges worldwide. The company commenced a public offering on 4 May 2007 under the ticker symbol NASDAQ: IBKR on the Nasdaq exchange. Barron's Magazine stated in 2009 that Interactive Brokers maintains a position as "the least expensive trading venue for investors", and has held the ranking as the lowest cost broker for five straight years. An analysis of their on-line website, however, indicates many higher charges than traditional brokers (e.g., borrow rates based on security prices rounded up to the nearest dollar, as opposed to industry standard of just 102% or price, etc.)
