What's better than momentum? Mo' momentum.

Let's take a closer look at five of this past week's biggest scorchers.

PLX Technology was last week's biggest winner, soaring 62% in a down week for the market. PLX is being acquired in a cash and stock deal that was initially valued at $330 million.

Imperial Sugar also soared on buyout news. The sugar company is being taken private in a $78 million deal.

Synacor also moved higher on acquisition news, but unlike PLX and Imperial Sugar, Synacor was the buyer. The streaming video specialist is snapping up Carbyn, the company behind an HTML5 platform that delivers a unified apps experience across Web-tethered devices.

Barnes & Noble was up as much as 90% higher after Mr. Softy agreed to a meaty investment in the company's Nook business. The book retailer gave back nearly two-thirds of its peak gains as the week wore on, but still closed out sharply higher on the perception that its Nook business may be worth more than the market originally thought.

VirnetX moved higher after cashing in on its intellectual capital. Aastra USA signed a patent licensing agreement with VirnetX. Aastra's shelling out a one-time payment and agreeing to ongoing royalties on certain IP-encrypted products.
