(Business Insider) Texan hedge fund manager J. Kyle Bass, founder of the $1.6 billion Dallas-based Hayman Capital, says there’s a “massive opportunity in energy.”Like many investors last year, Bass had been predicting a rebound in oil prices in 2015. That didn’t happen. Oil prices continued to slide, falling below $35 a barrel on December 18, making it one of Hayman’s worst years in a decade.
