Career.
Hwang began his career at Hyundai Securities in New York, after which he worked at the now defunct Peregrine. At Peregrine, he met Julian Robertson as one of his clients. Hwang went to work for Robertson's Tiger Management. Robertson closed his hedge fund in 2000, but handed Hwang about $25 million to launch his own fund, Tiger Asia Management, which grew to over $5 billion at its peak. Robertson’s former proteges are known as the Tiger Cubs, and Hwang was considered one of the most successful among them. Tiger Asia suffered heavy losses in the global 2008 financial crisis.
In 2012, Tiger Asia Management and Hwang paid a $44 million settlement to the U.S. Securities and Exchange Commission in relation to insider trading.
In 2014, Hwang was banned from trading in Hong Kong for four years.
Archegos Capital Management.
In 2012, Hwang closed Tiger Asia, and opened a family office, Archegos Capital Management, which managed US$10 billion of family money. As a family office, they were less regulated than as a hedge fund.
In March 2021, the losses at Archegos Capital Management triggered the liquidation of positions approaching $30 billion in value, leading to substantial losses to Nomura and Credit Suisse.
Before the losses Hwang was believed to be worth $10–15 billion with his investments leveraged 5:1.
