JPMorgan's sprawl is only helping so much. The mega-bank credited diversification for its better-than-expected first-quarter profit of $5.5 billion. Indeed, loans grew by nearly a fifth while investment banking stalled. Borrowers in the energy industry cost some $500 million, though. It'll take more than this performance to defend a business model on the back foot.
