Overstock.com was a big winner, soaring on Thursday and Friday after posting blowout quarterly results. Analysts expected the online discounter of closeouts, clearance items, and other overstocks to post a small loss for the period. Instead, Overstock.com came through with a surprising profit.

SUPERVALU may be a super value to at least one private equity firm. Shares of the struggling grocery store chain rallied on reports that Cerberus is trying to drum up financing to make a play on the company.

TASER came through with -- wait for it -- stunning results. The stun gun maker reported a profit of $0.07 a share on an 18% spike in net sales. Analysts weren't as trigger happy. They were only looking for net income of $0.04 a share on a mere 5% top-line advance.

3-D printing continues to grow at an impressive rate. Niche leader 3D Systems came through with a strong report. Even if we back out a recent acquisition, we're still looking at organic growth of 26%.

Finally, we have Facebook giving bulls a good week. The social networking website operator now has more than a billion monthly active users. In posting solid financial results, Facebook also emphasized how well its mobile monetization efforts are doing. Facebook was even trying to make money off its smartphone users, but now mobile is accounting for 14% of its ad revenue.
