On Tuesday's edition of MarketFoolery, host Chris Hill and Motley Fool analysts David Hanson and Bryan White take a deep dive into the biggest stories for investors today.

Even though Krispy Kreme's Q3 profit rose 34%, with same-store sales growth for the 20th consecutive quarter, KKD stock took a major blow today. In the lead segment on today's MarketFoolery, David and Bryan discuss why the market reacted so negatively to the company's same-store sales and guidance, and why "cannibalization" may have just become a four-letter word to the company. The guys then tell investors what they think of the stock today, and what Krispy Kreme's prospects for the future look like.

Then, with the number of U.S. banks sinking to historic lows at the moment, are consumers getting pinched with a lack of banking choices? How does this affect investors in this sector? David and Bryan discuss the move to online banking, how both banking consumers and investors will be affected, and which banks win out in this fundamental shift in the banking business.

And finally, how will the Amazon.com drone story play out? The guys discuss what a future of ubiquitous drone utilization would look like, and whether Amazon has any competition in this venture.
