In this video from Thursday's Investor Beat, host Chris Hill and Motley Fool analysts David Hanson and Taylor Muckerman dig into the biggest stories for Foolish investors from the market today.

eBay reported its quarterly numbers today, with fourth-quarter revenue up 13%. This news, however, was overshadowed by well-known billionaire activist investor Carl Icahn, who owns a 0.82% stake in eBay, who publicly demanded that the company spin off its PayPal business in order to create value for shareholders. In the lead story in today's Investor Beat, the guys discuss Icahn's motivations here, why eBay turned him down, and whether or not spinning off PayPal would actually make sense today.

Then, the guys take a look at four stocks making moves on the market today. McDonald's was one of just a few Dow components not in the red today. Fourth-quarter revenue rose 2%, but global same-store sales fell by 0.1%. Netflix popped big today, after the company announced in its fourth-quarter results that it had added more than 2.3 million subscribers to its video streaming business. Herbalife fell hard after Massachusetts Senator Ed Markey urged both the SEC and the Federal Trade Commission to investigate the company's business practices. And Noble Corp. delivered pretty good Q4 results, but shares hit a new 52-week low today after the offshore drilling company said it expects lower rig utilization.

And finally, David tells investors why he'll have his eye on the biggest homeowner in the U.S., Blackstone, while Taylor is looking to Honeywell for some possible new innovations when the company announces earnings tomorrow.
