In this segment from Monday's Investor Beat, Motley Fool analysts Evan Niu and Taylor Muckerman highlight what they're watching on the market this week. Evan points to Splunk (SPLK), a machine data engine that could be a play on the coming "Internet of Things," that has sold off dramatically along with the rest of the tech sector recently. Meanwhile, Taylor is taking a look at CSX Corp. (CSX 0.32%), which will be reporting earnings tomorrow after a brutal winter, to see how strongly they were affected by the harsh weather.
