Jamie Dimon, chairman and CEO at JPMorgan Chase, led the bank through the financial crisis to emerge larger, stronger and healthier than competitors. Rather than basking in adulation, Mr. Dimon remains concerned, according to The New York Times. He learned from missteps of other banking giants and openly worries that legislation to overhaul financial regulation would hit his bank and possibly the broader economy. He's also aware that rivals are working on ways to "clean our clocks." However, despite Mr. Dimon's subdued demeanor, JPMorgan's prospects appear brighter than he might be publicly acknowledging.
