Bancorp Rhode Island was the market's biggest winner, soaring 43% after agreeing to be acquired by Brookline Bancorp (Nasdaq: BRKL). Class action lawyers are circling the $234 million deal, but it's likely to stick. The premium for the regional banker was fair enough to send shares of Brookline lower on the news.

Quepasa took off after rolling out the beta version of a FarmVille-esque social game called Wonderful City. The social network aiming for Hispanics is still trading for roughly half of its speculative January highs when some investors were mistakenly trading it as a publicly traded proxy for Facebook.

Quepasa.com has been held back in the past by its crummy engagement metrics. It served up a mere 214 million pages last month to its cumulative base of 33.6 million registered users. Can you imagine the average Facebook user going through just six pages a month? In reality, the vast majority of Quepasa's registrations are inactive. Quepasa claims that repeat visitors go through an average of nearly 25 pages per visit, implying that either millions of users visit infrequently or fewer still visit often. A sticky online game can obviously improve Quepasa's outlook, so keep your eye on April's metrics in a couple of weeks.

Select Comfort shareholders are sleeping pretty. The maker of air-chambered Sleep Number mattresses posted blowout quarterly results and jacked up its guidance. It may seem hard to believe, but opportunistic investors were able to pick up shares of Select Comfort for as little as $0.20 two years ago. The premium mattress manufacturer is now trading in the high teens.

Banro struck gold after the Toronto, Canada-based gold explorer revealed Thursday that it was in negotiations for a proposed joint venture transaction with China Gold International. It had initially addressed the speculation earlier in the week.

TradeStation pulled out of the station after signing off on a $411 million deal to be acquired by Japanese online broker Monex.
