What's On: Nat Gas, Corn and Quarterly Reports

Here's what's up on Tuesday's Squawk on the Street:

--A big day of quarterly reports. Bank of America showing a $7.3 billion loss. Goldman Sachs reporting as well. Then we're getting numbers from Coca-Cola too. Also on the list this morning, Johnson and Johnson. We'll see how the markets react at 9:30 on the dot.

--Plus the McDonald's indicator. We've been tracking this stock ahead of Thursday's quarterly report as one Wall Street analyst says the time to make money on McDonald's is in the days before the company reports.

--As a few major banks re-start the foreclosure process we're talking live with Texas' Attorney General who's been on the forefront of the freeze.

--Plus, two for Tuesday ... nat gas has been beaten up badly in the last several weeks. Corn's really been on the rise. Are the two about to reverse course?

And our Street Poll asks about something new called the "Twitter indicator." Are investors better off tracking market sentiment on twitter or is the traditional data still the best indicator?
