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

--Alcoa the morning after. See how investors are reacting to the numbers as earnings season gets underway.

Plus a special look at the auto sector in the wake of Alcoa's report. We'll take General Motors, Ford, Toyota and Honda for a test spin.

Also on the big show, the financials after a rough day on Wall Street and how the stocks might react to credit scores - we have the man in charge of FICO. What he says could have a big impact on stocks like Citigroup, JP Morgan, Bank of America and Capital One.

And the Street Poll: No matter which side of the trade you're on you have to admit there is fear on Wall Street and Main Street and blood in the water. Call it the wall of worry — fears over weak banking results, no deficit deal, fear Italy in trouble, fear Greece will default on some bonds. So we want to know what has you most worried these days if anything at all? Share your opinion.
