George Soros is a Hungarian-American billionaire investor, philanthropist, and author. He is widely considered one of the most successful hedge fund managers in history, having founded Soros Fund Management and the legendary Quantum Fund in 1970 alongside Jim Rogers.
Soros is renowned for his theory of reflexivity, which posits that market participants’ biases and perceptions actively alter market fundamentals, creating vicious and virtuous self-reinforcing boom-and-bust cycles that can be systematically monetized.
