In this video from Monday's edition of Investor Beat, host Chris Hill and Motley Fool analysts Taylor Muckerman and Jason Moser dissect the hardest-hitting investing stories from the market today.

The Consumer Electronics Show, or CES, begins tomorrow in Las Vegas, and is the largest consumer tech trade show in the world. In the lead story on today's Investor Beat, Taylor and Jason discuss the idea of a smart home and the "Internet of things," and how the increasing interconnectedness of the appliances and devices in our lives could be a multitrillion-dollar industry over the course of the next decade. They also note that while there can be a lot of buzz and excitement generated by new products each year at CES, the timeline for when these stories may play out for investors can be very difficult to gauge.

Then, Taylor and Jason discuss four stocks making moves on the market today. SolarCity hit an all-time high today, after the stock got an upgrade from Goldman Sachs. Twitter, on the other hand, was down today on news of another downgrade for the high-flying new social-media stock, this time coming from Morgan Stanley. SiriusXM rose today on the first day of trading since Liberty Media announced it wanted to acquire the entire company; Liberty currently owns about 53% of SiriusXM. And finally, Pandora saw a big pop today, on news that its number of active listeners for December was up 13% year over year.

And in today's final segment, Taylor tells investors why he'll have a close eye on Monsanto's new product pipeline when the company reports earnings on Wednesday, while Jason is hoping to see some new technology when 3D Systems presents at CES tomorrow.
