Jon Najarian

Jon Najarian — “Doctor J” — started his career on the floor of the Chicago Board Options Exchange, where mispricing risk cost real money the same afternoon. That market-maker discipline still sets the entry, the size and the invalidation level on every idea he publishes for the club.

He co-founded optionMONSTER and the unusual options activity tooling that professional desks still lean on, and has spent thousands of hours on CNBC translating order flow into plain English for non-professional investors.

Inside Rebel Investors Club, Jon writes the flow-driven desk notes: what unusual premium hit the tape, why it matters, and what he would need to see to act on it.
