Since then, the three major indexes notched their bestquarterly gains in nearly a decade in the first quarter, buthave been in a holding pattern in April ahead of first-quarterearnings season.
JPMorgan, effectively kicking off the quarterly earningsreporting season that will dominate Wall Street's agenda for thecoming weeks, breezed past analyst estimates, easing fears thatslowing economic growth could weigh on its results. Its stockrose 4.5% and led a broad rally in bank stocks.
"I think people were heading into this earnings seasonfearing the beginning of an earnings recession. The JPMorgannews has given them a little bit of hope," said Robert Pavlik,chief investment strategist, senior portfolio manager atSlateStone Wealth LLC in New York. "I would liken it to someonedrifting on a raft and seeing land."
