<span style="line-height: 20.8px;">Ken Griffin's hedge fund firm, Citadel, has performed very well in recent years while most other hedge funds have disappointed. Griffin's great run continued in </span>2015,<span style="line-height: 20.8px;"> when his main hedge funds posted returns of 14.3% net of fees. Citadel's Global Equities hedge fund returned 17.2% net of fees and its Tactical Trading fund posted a 16% net return. But Citadel was dealing with some losses at the start of 2016. Griffin recently moved to buy a $200 million condo complex in a Manhattan tower that is under construction. He also bought two paintings for $500 million. Griffin, who began trading in the 1980s in his Harvard dorm room, founded Citadel in 1990 with approximately $4 million. The firm now manages some $25 billion in assets. Griffin filed for divorce in 2014 from his wife of 11 years, Anne Dias Griffin, a Goldman Sachs alum who is also a money manager. The contentious divorce proceedings in Illinois state court ended with a settlement in 2015.</span>
