Hedge Fund - Cortex Capital Management

A long-time lieutenant of billionaire Lee Ainslie is starting his own firm. Andrew Warford left Dallas-based Maverick Capital after 18 years in 2021.

Shares of Cerner are up 20% this year but the medical records company can still rise much further as it is still cheap, activist investor Jeff Smith said Tuesday.

Cortex Capital Management was spun out from Kleinheinz Capital Partners by Mark Stupfel in 2013. John Kleinheinz, the former boss of Stupfel is one of the investors of Cortex Capital Management.

Mark Stupfel’s Cortex Capital Management has filed its 13F with the SEC for the reporting period of March 31.

Mark Stupfel launched his own hedge fund, Cortex Capital, using an investment from its former employer, John Kleinheinz.
