Let's start with Inteliquent. The company saw its stock soar 51% after announcing that it will sell its global data business in a move that raises money, improves adjusted EBITDA, and lowers its capital expenditures. The move frees Inteliquent to focus exclusively on its more lucrative voice-services business.

AMD soared on favorable analyst comments about new products in its FX series of chips. There was also speculative chatter suggesting that AMD will have a presence in the new Xbox that will be unveiled later this month. Another rumor has AMD as a buyout candidate for its larger rival.

SolarCity's prospects brightened after the country's leading solar-panel installer announced the opening of its largest U.S. operations center in California to satisfy growing demand. SolarCity's appeal comes from buyers' ability to purchase solar panels in monthly installments, ideally in line with the money that they're saving on their electricity bills.

Sonus Networks moved higher after posting a smaller loss than analysts were expecting. Sonus added 138 new session border controller customers during the quarter, and its top-line guidance will have Wall Street revising their forecasts higher.

Finally, shares of 3D Systems rose after posting healthy growth in its latest quarter. 3D Systems also won some new believers later in the week, when it revealed that Staples, the country's largest office-supplies retailer, will begin stocking its entry-level 3-D printer.
