Citigroup's Fine, Earnings, Yahoo Awaits Alibaba Boost, Cramer Likes Boeing

U.S. futures are set to rebound after the market had a tough week last week. The market is pressing on with earnings, expecting Citigroup to announce numbers -- and perhaps even more news -- later today. Yahoo's Marissa Mayer has continued her acquisitive streak, tucking in RayV last week to bolster the company's video platform. But, the Alibaba IPO could mean much more for Yahoo's CEO, as well as the company's shareholders. And the market is keeping an eye on Boeing stock, as is Jim Cramer: he's calling the company's order backlog good news and is putting a bullish target on the stock. ¿
