A mega rally on Wall Street sent financial shares to their biggest gain ever after a better than expected profit report from Wells Fargo and a sharp drop in oil prices.

Merrill Lynch reportedly has a deal in place to sell its 20 percent stake in news and data provider Bloomberg LP for $4.5 billion to $5 billion. The brokerage is set to release earnings today. Yesterday, its shares rose 13 percent.

After the close yesterday, eBay said second-quarter profit rose 22 percent after customers listed more items for sale and revenue at its PayPal payment unit jumped. The online auction site also raised its full year forecast. Net income climbed to $460.3 million, or 35 cents a share, up from 27 cents, a year earlier. Revenue rose to $2.2 billion from $1.83 billion.

Here's how things start out today:
The Dow starts out at 12,239.
The Nasdaq starts at 2,284.
