Among the companies with shares expected to actively trade in Monday's session are Apple Inc. (AAPL), Harry Winston Diamond Corp. (HWD) and HHGregg Inc. (HGG).

Apple has cut its orders for components for the iPhone 5 due to weaker-than-expected demand, indicating sales of the latest smartphone haven't been as strong as previously anticipated, according to a report in The Wall Street Journal, which cited people familiar with the situation. Apple's orders for iPhone 5 screens for the January-March quarter, for example, have dropped to roughly half of what the company had previously planned to order, the people said. Shares fell 2.7% to $506.50 premarket. Shares of component suppliers also trading lower. Avago Technologies Ltd. (AVGO) fell 1.6% to $33.78, Cirrus Logic Inc. (CRUS) dropped 4.5% to $30.15 and Qualcomm Inc. (QCOM) fell 1.6% to $63.85.

Swatch Group AG (UHR.VX) said Monday it had agreed to buy Harry Winston Diamond's luxury brand diamond jewelry and timepiece division for $750 million plus the assumption of up to $250 million of pro forma net debt, in an acquisition that strengthens its presence in the U.S. market and helps it expand into jewelry. The deal doesn't include Harry Winston's mining activities, which will change its name to Dominion Diamond Corp. when the transaction is completed. Harry Winston shares rose 9.4% to $15.82 premarket.

Appliance and electronics retailer HHGregg logged weaker-than-expected fiscal third-quarter results amid a projected 10% drop in same-store sales. The company noted it didn't play the loss-leader game over the holidays in order to bolster margins, which did improve the metric companywide. But the sale shortfall meant earnings per share won't be as robust as analysts hoped. Shares fell 6.1% to $7.41 premarket.

Francesca's Holdings Corp. (FRAN) has raised its guidance for the fourth quarter, citing its holiday sales and margin performance. Shares rose 8% to $30.50 premarket.

Alamos Gold Inc. (AGIGF, AGI.T) said it has commenced an offer to acquire Aurizon Mines Ltd. (AZK, ARZ.T) for $780 million Canadian dollars (roughly $792 million) in cash and shares. Toronto-based Alamos said Aurizon shareholders can opt for C$4.65 (about $4.73) in cash or 0.2801 of an Alamos share for each share held. Aurizon shares rose 27% to $4.40 premarket.

SunPower Corp. (SPWR) said Friday that it expects to incur $33 million to $40 million in restructuring charges, with most of those costs to be booked in the fourth quarter. The solar-panel maker and developer of solar power plants said the charges are related to a plan announced in October. Shares fell 3.1% to $7.94 premarket.
