3D Systems, Sotheby's & Rackspace Report Earnings, Kirk out for Merck

We're getting ready for another week of earnings, and this morning there's one 3D printer coming out with numbers after a rough year: 3D Systems is expected to report lower earnings than it did last year before the open this morning and the stock is down about 60 percent so far in 2014. With new competitors in the form of Silicon Valley titans, the industry could be in for sea changes. Plus, we'll also get numbers from Sotheby's -- perhaps the auction house can pare losses, in a frothy art market. And Jim Cramer has added a new pharma player to his portfolio -- we'll break down his Action Alert Pick.
