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. Today, he is a professional investor, money manager, media analyst, and co-founder of optionMONSTER.com and tradeMONSTER.com.
Jon developed and patented trading applications and algorithms used to identify unusual activity in stock, options, and futures markets. optionMONSTER.com, an options news and education site, which Jon co-founded with his brother Pete, has been described by Securities Industry News as "content king of the options business".
tradeMONSTER.com 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.
The brothers also head Najarian Consulting, a company advising money management firms and co-authored the book, "How We Trade Options."
