Billionaire investor Bill Ackman has a flair for the dramatic and often makes bold moves. This year has been no exception.

Ackman made about $1.7 billion from a bet on higher interest rates and incurred a $400 million loss on a Netflix (ticker: NFLX) investment held for just a few months. His Pershing Square Tontine Holdings, the largest special purpose acquisition company, had to return $4 billion of investor capital in July after its planned acquisition of a 10% stake in Universal Music Group (UMGNF), the music publisher, ran into regulatory roadblocks.
