Today, he is a professional investor, money manager and media analyst.

He developed and patented trading applications and algorithms used to identify unusual activity in stock, options, and futures markets. optionMONSTER, the options news and education site he co-founded, was described by Securities Industry News as “content king of the options business”.  For years, tradeMONSTER was consistently rated “Best for Options Traders” by Barron’s and was the first online broker to deploy streaming, desktop-like trading in a web browser.

In 2016 Jon and Pete co-founded Najarian Advisors, a company advising institutional investors on options strategies. Also, the brothers invest in and work with start-ups via Rebellion Partners, a venture consulting firm they launched in 2015.
