The 42 richest hedge fund managers in the world

Forbes' magazine has just released its annual list of the world's billionaires.

This year, we've counted 42 names in the hedge fund industry. A few of these titans have retired in recent years.

Overall, 2015 was disappointing year in terms of hedge fund performance. The average hedge fund fell 3.64% in 2015, according to Hedge Fund Research.

Even some of the billionaire fund managers had losing years, including Bill Ackman (Pershing Square), David Einhorn (Greenlight Capital), Larry Robbins (Glenview Capital), and John Paulson (Paulson & Co.), causing them to fall in the ranks.

That said, some of these titans have seen their wealth increase thanks to strong performance, including Steve Cohen (Point72 Asset Management), Ken Griffin (Citadel), and George Soros (Soros Fund Management).

We've included a round up of the richest fund managers in the world.
