U.S. HOT STOCK FUTURES: HOT STOCKS TO WATCH

Among the companies with shares expected to actively trade in Tuesday's session are Ruckus Wireless Inc. (RKUS), EOG Resources Inc. (EOG) and Santarus Inc. (SNTS).

Ruckus's first-quarter profit fell 92% as operating expenses at the Wi-Fi networking company surged, overwhelming stronger revenue. Shares sank 17% to $15.70 after hours, as results missed analysts' expectations and the company offered a downbeat second-quarter view.

EOG Resources's first-quarter profit rose 53% as revenue at the natural-gas-and-oil producer strengthened, led by its largest crude oil and condensate segment. Shares rose 3.6% to $130.60 after hours as results sharply topped consensus estimates.

Santarus's first-quarter profit soared amid strong sales growth led by its Glumetza diabetes treatment and the relaunch of its Zegerid drug for certain upper gastrointestinal disorders. The specialty biopharmaceutical company's shares were up 13% at $21.25 in recent after-hours trading as adjusted earnings and revenue topped expectations and the company boosted its 2013 guidance.
