Bill Hwang, the Wall Street investor who ‘lost’ US$20 billion in days, is a devout Christian who gave away millions to good causes

Korean-American “Tiger Cub” investor Bill Hwang was once known as “the greatest trader you had never heard of”. Ironically you’re more likely to have heard of him since March – when his US$20 billion net worth was reportedly wiped out in 10 days. The sudden collapse of Hwang’s New York-based Archegos Capital Management has been called the fastest single loss by an individual in history. It also imposed huge losses on his bankers Nomura and Credit Suisse, raising fears of another global banking meltdown.

So how did the modest, churchgoing 57-year-old end up here?
