On Monday's edition of Investor Beat, host Chris Hill and Motley Fool One analyst Jason Moser take a hard and fast look at the biggest investing stories as we step into the holiday retail season.

Now that Amazon.com CEO Jeff Bezos has revealed that his company is testing a way to use automated flying drones to deliver packages to consumers, is Amazon a buy? In the lead segment on today's Investor Beat, Chris and Jason discuss whether this could revolutionize the way packages are delivered, and whether FedEx and UPS should be scared of the flying drone takeover.

Then the guys take a look at three stocks making moves on the market today. Shares of 3M have been beating the market in 2013 but fell today after getting downgraded by Morgan Stanley. Groupon had a similar day: The daily-deal stock is up big in 2013 but pulled back today on news of a downgrade from Goldman Sachs. And Twitter dropped a bit today, now that the company's quiet period has ended, as five analysts came out with their first reports on the company.

Finally, Jason tells investors why Krispy Kreme is his stock to watch for the week, and gives a picture of what to look for when the company reports earnings tomorrow.
