Mark Lasseigne fills you in on what's happening on Wall Street.

-Wall Street surged as blue chip stocks have their best day of 2011. 
-The Dow Jones Industrial Average added 202 points to 12,587
-Enthusiasm over earnings results from IBM and Coke, coupled with some optimism toward a potential US deficit-reduction plan, help drive stocks to their highest levels in more than a week.
IBM alone accounted for 75 points of the Dow's gains.
-After the market close, Apple reported earnings, that blew away Wall Street expectations, driven by blockbuster sales of iPhones and iPads.
