Sequans Communications didn't seem to garner a lot of attention when it went public last month. Things changed last week when UBS, Needham, and Jefferies & Co. all initiated coverage with bullish ratings. These are the firms that took the French company public last month. Now they get the opportunity to sing Sequans' praises as a sexy 4G play for its WiMAX-proficient ways.

Skyworks (Nasdaq: SWKS) is acquiring power management specialist Advanced Analogic Technologies. The cash and stock deal was originally valued at $6.13 a share, a juicy premium to where Advanced Analogic was trading before the deal was announced.

Last week was a good one for jewelers as Tiffany and Zale posted better-than-expected quarterly results. The historically downtrodden Zale came through with the biggest bounce, given the huge 15% spike in same-store sales and its narrowing deficit.

Shares of Krispy Kreme glazed their way toward a fresh 52-week high after the doughnut maker posted better-than-expected quarterly results. Krispy Kreme's profit of $0.13 a share clocked in well ahead of the $0.09 a share that analysts were looking for. Now I know why the neon "Hot Doughnuts Now" sign is on.

Finally, we have Quantum Fuel Systems revving up after announcing a deal with Dow Chemical (NYSE: DOW) for more than 100 plug-in hybrid electric pickup trucks.

It was a great week for these five stocks. Let's see if they're up for an encore.
