Einhorn v Klarman in the Great Fracking Fracas

In the red corner, weighing in at $12bn funds under management, the baby-faced assassin, David Einhorn. Owner of a surprisingly powerful left jab and a mean poker player, the New York born and bred Einhorn ('unicorn' in German) recently slammed oil fracking companies generally and Pioneer Natural Resources in particular (in his words, 'the mother fracker'). Here's Einhorn's short case on Pioneer Natural Resources. (VIEW LINK) In the blue corner, weighing in at $20bn+ under management - don't let his quiet demeanour fool you, this kid's the knockout king - Seth Klarman. More at home on a race track than in a World Series of Poker tournament, Klarman still plonks down a big pile of chips when the odds are favourable. His largest new bet placed in the first quarter, according to today's 13F filing from Baupost? A $500m+ long punt on Pioneer Natural Resource. Ding ding.
