About Us

A software engineer, inventor, and handyman, Marco was introduced to computers at an early age while attending a boarding school in the Swiss Alps. He was the only one to request to be in the computer lab when a shiny new Apple II arrived rather than participate in the skiing outings. After stints at prestigious investment firms like Citadel, he began thinking of ways to automate the repetitive task of managing a strategy. That work eventually became Portfolio123.

Former banker at Northern Trust and researcher for an investment research app he co-founded, Hem has experience in both worlds. After partnering with a friend to start a financial research app, he started managing client investment accounts before coming onboard with Portfolio123. He has a very curious personality and enjoys learning new things every day. He's a strong follower of the motto “work hard, play hard” and “Give 100% to everything!”

Yuval invests primarily in microcaps; investigates investment conundrums; and writes about his investigations on his blog, invest(igations) and on Seeking Alpha. He worked for thirty years as an editor at publishing houses in New York City and Chicago. He is the author of Zora and Langston: A Story of Friendship and Betrayal (Norton, 2019) and other books.

Paul has worked at several companies over the years, as an analyst, a writer, an editor, and a financial data expert. Those companies included Oppenheimer, Value Line, Multex.com, and Reuters.

Riccardo began trading securities before graduating high school, and won the collegiate European University Trading Challenge.
