U.S. Hot Stocks: Hot Stocks to Watch

Among the companies with shares expected to actively trade in Tuesday's session are Best Buy Co. (BBY), Burger King Worldwide Inc. (BKW) and DSW Inc. (DSW).

Best Buy posted a stronger-than-expected quarterly profit as the electronics retailer's cost-trimming and e-commerce initiatives started to pay off, though sales continued to decline with no immediate sign of a letup. Shares declined 4.2% to $30.66 premarket.

Burger King agreed to buy Canadian coffee-and-doughnut-chain Tim Hortons Inc. (THI, THI.T) for about $11 billion, confirming plans to move the iconic American brand north of the border under a tax inversion deal with the help of billionaire investor Warren Buffett. Burger King shares edged up 2% to $33.04 premarket.

DSW said fiscal second-quarter profit edged up 1.8%, with results outpacing market expectations as net sales and same-store sales increased across its segments. The discount shoe retailer also raised both ends of its full-year per-share earnings guidance by five cents. Shares surged 11% to $31.50 premarket.

Sanderson Farms Inc. (SAFM) said its fiscal third-quarter profit rose 12%, driven by higher sales and poultry product prices. The results, however, fell far short of analysts' expectations, sending shares down 5.9% to $89.56 premarket.

Trina Solar Ltd. (TSL) said it swung to a profit in the second quarter, but its solar-module shipments in the period fell just shy of expectations. Shares dropped 6.7% to $12.48 premarket.
