The following video is from Monday's edition of Investor Beat, in which host Chris Hill and Motley Fool analysts Jason Moser and Bill Barker dissect the hardest-hitting investing stories of the day.

The shutdown of the U.S. federal government is entering its second week, but perhaps even more concerning for investors is the coming debt ceiling debate. If the debt ceiling isn't raised and America begins defaulting on its debts, the consequences could be dire. In the lead story on today's Investor Beat, Jason and Bill discuss just how bad default would be and why not raising the debt ceiling has no upside.

They also discuss four stocks making big moves today. Apple gets an upgrade from Jefferies, with a price target of $600. Cooper Tire falls on news that its acquisition by rival Apollo Tyres may be up in the air. Liquidity Services is down big today as the online marketplace for surplus goods gets a downgrade from Bank of America. And sandwich shop Potbelly continues its incredible run since its IPO on Friday.

And finally, our analysts share why they'll be watching shares of Fastenal Company and Yum! Brands as earnings season begins.
