Jon “DRJ” Najarian was linebacker for the Chicago Bears before he turned to another kind of contact sport – trading on the Chicago Board Options Exchange.
He became a member of the CBOE, NYSE, CME and CBOT and worked as a floor trader for some 25 years.
In 1990 he founded Mercury Trading, a market-making firm at the Chicago Board Options Exchange (CBOE), which he sold in 2004 to Citadel, one of the world’s largest hedge funds.
During that time Jon developed the Heat Seeker™ algorithm and framework used to identify unusual activity in stock, options and futures. He still uses it to this day to identify unusual option activity on CNBC.
In 2005, Najarian co-founded, together with his brother Pete,optionMONSTER, an options news and education firm, andtradeMONSTER, a leading online brokerage firm, that for years has been rated “Best for Options Traders” by Barron’s and was the first online broker to deploy streaming, desktop-like trading in a web browser. Jon and Pete took on private equity firm General Atlantic Partners as a partner in 2014, ultimately selling TradeMonster toE*Trade for $750 million in 2016.
Today Jon is a professional investor and market analyst, who publishes his market observations and trade ideas on Investitute.com, his financial education and newsletter services company. Over the years he has authored four best-selling books on trading and options.
