Among the companies with shares expected to actively trade in Wednesday's session are Dell Inc. (DELL), Williams-Sonoma Inc. (WSM) and Sunrise Senior Living Inc. (SRZ).

Dell's fiscal second-quarter earnings fell 18% as the computer giant recorded weaker revenue, led by declines in its consumer segment. Shares slid 6.2% to $11.58 premarket as revenue missed the company's expectations. Dell also lowered its full-year guidance and offered downbeat revenue guidance for the current quarter.

Williams-Sonoma's revived gross margin and strong sales growth lifted the housewares and furniture retailer's profit 10% in its fiscal second quarter. The better-than-forecast results pushed shares 11% higher premarket to $42.20.

Health Care REIT Inc. (HCN) agreed to acquire Sunrise Senior Living in a roughly $845 million deal that would make the real-estate investment trust among the largest owners of senior housing in the world.

Toll Brothers Inc.'s (TOL) fiscal third-quarter earnings rose 46% as the luxury home builder saw strong revenue gains across all its geographic segments, buoyed by what it called the most sustained demand it has seen in more than five years. Shares rose 3.9% to $33.05 in premarket trade.

Express Inc.'s (EXPR) fiscal second-quarter earnings rose 26%, though the young-adult clothing retailer's sales grew more slowly than expected amid increased promotional activity in the latter part of the period. Shares slumped 9.5% to $15.30 premarket as the company also lowered its full-year earnings target.

Career Education Corp. (CECO) said Chief Financial Officer Michael J. Graham has resigned to accept a position at another company and named Colleen M. O'Sullivan, most recently the company's chief accounting officer, as his replacement. Shares fell 9.6% to $3.38 premarket.
