On Tuesday's edition of Investor Beat, host Chris Hill and Fool analysts Matt Koppenheffer and David Hanson take a hard-hitting look at today's biggest investing news.

Last month Joseph A. Bank offered to buy rival Men's Wearhouse for $2.3 billion. Men's Wearhouse immediately rejected the offer, but today turned the tables and made an offer to buy out Joseph A. Bank for $1.5 billion. Both stocks were up on the news. Is now the time for investors to get in on Men's Wearhouse? In the lead story on today's Investor Beat, Matt and David take a look at why the deal makes sense, and whether they would want to be a shareholder of the new merged company.

Then the guys look at four stocks making moves on the market today. Cracker Barrel's first-quarter profit rose 17%, but shares were down after the restaurant lowered guidance. Shares of Tiffany were up on the news that third-quarter profits rose 50%. The company also raised guidance, and saw same-store sales rise 7%. Twitter moved upward slightly today, with the company's new head of retail advertising hoping to lure more advertisers this holiday season. And finally, Barnes & Noble took a tumble after second-quarter revenue fell 8%, with the company's digital book division down 30%.

And finally, Matt and David tell investors why they'll have their eyes on eBay and Cerner this week.
