Millennial Media soared after posting a narrower loss than Wall Street was expecting. The mobile advertising provider is now serving up ads for developers in more than 35,000 different mobile applications.

Fusion-io came up big after the storage drive maker posted blowout quarterly results and issued inspiring guidance. Fusion-io sees revenue growth of 45%-50% in its new fiscal 2013, well ahead of where the pros were perched.

Universal Display put the "oh" in OLED after the patent-rich lighting pioneer served up robust quarterly results.

First Solar was also a bright star last week. Seeing a solar company post improving results is rare, but seeing one enjoy a boost in profit guidance is even more rare.

Zipcar shares surrendered 39% of their value two weeks ago after posting brutal quarterly results. The leading car-sharing service shifted out of reverse last week, starting to make back some of the ground that it had lost.
