Rosen wrote the “10 Things Before the Opening Bell” newsletter, and he also wrote big picture analysis of the markets and the economy.

Rosen has reported for Fortune magazine, BuzzFeed News, GreenBiz, and US-China Today, among other outlets, and is the author of two No. 1 Amazon bestsellers: “Life Between Moments: New York Stories,” a work of fiction, and “Everywhere But Home,” a travel memoir based on his time living in Southeast Asia.

He earned his Master’s of Science at the University of Southern California as an Annenberg Fellow, and previously studied kinesiology and philosophy at San Diego State University.
