U.S. Hot Stocks: Hot Stocks to Watch

Among the companies with shares expected to actively trade in Monday's session are Bridgepoint Education (BPI), Hillshire Brands Co. (HSH) and Pinnacle Foods Inc. (PF).

Bridgepoint warned that it will miss the deadline to file its latest quarterly report to the Securities and Exchange Commission and projected disappointing results for the period. The company said the delay is related to an SEC comment that the company's revenue recognition policy and accounting for doubtful accounts may need revising. Shares dropped 12% to $14 in light premarket trading.

Hillshire on Monday said it agreed to buy Pinnacle Foods for roughly $4.3 billion in cash and stock, giving the packaged-meat producer a broader line of grocery staples. Pinnacle shareholders will receive consideration of $36.48---a 20% premium over Friday's closing price. Pinnacle shares surged 20% to $36.50 premarket, while Hillshire edged up 2.3% to $37.80.
