Still John Silvia, chief economist with Wachovia, said that he believes the markets may weather the bad news from the bank.

Stocks rallied earlier this month when No. 1 bank Citigroupwarned of an even bigger drop in earnings from subprime problems, because it helped answer market uncertainty about how bad problems were in the sector. Silvia said there could be a similar relief rally on this report.

Silvia said that strong tech earnings could help markets weather the bad news from Bank of America.

"The high tech sector seems to be doing well," he said.

Another tech bellwether, Nokia (Charts), the world's largest maker of cell phones, reported a 90 percent jump in earnings early Thursday. That was twice the gain in earnings forecast by analysts surveyed by First Call.
