Web.com got a boost when it made a model-altering purchase. Web.com is buying the much larger Network Solutions. The purchase will be accretive to earnings. It will also triple Web.com's customer base, giving it a substantially greater audience to market its web services to.

It was generally a bad week for health-care stocks, but that certainly wasn't the case for Emdeon. Blackstone Group (NYSE: BX) agreed to buy the health-care billing specialist in a $3 billion deal. Shareholders will be taken out at $19 a share.

Caribou announced plans to expand its consumer packaged goods business. It also came through with a strong quarter, as earnings nearly doubled, fueled by a 16.5% uptick in consolidated sales and a healthy 4.6% gain in store-level comps.

STAAR Surgical made the cut after posting strong results and raising its 2011 outlook. The maker of minimally invasive ophthalmic products delivered a slightly better than projected profit on a 19% revenue spurt.

Shares of j2 also followed in STAAR's footsteps of posting a blowout quarter and sweetening the deal by bumping its guidance higher.

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