Outsourcing specialist APAC led all of the market gainers, soaring nearly 60% higher after agreeing to be acquired by JPMorgan Chase's (NYSE: JPM) private investment subsidiary. Ambulance-chasing attorneys are trying to drum up interest for a class action suit, but they're unlikely to succeed given the generous buyout premium.

Borun again? China New Borun notched big gains during the first three days of the abridged trading week after announcing that it would be continuing its relationships with its existing audit team. Given the way accounting scandals have blown up small Chinese companies in recent months, keeping independent auditors from scurrying away is important.

There wasn't any material news driving Sky-mobi higher, but what else is new? Volatility is no stranger to the Chinese mobile app store operator, which often finds itself as one of the market's biggest winners or losers from week to week.

Shares of medical robotics specialist Hansen Medical went "MMMpop" to hit a new 52-week high last week, fueled by excitement for the potential approval of a new vascular robotic system.

Rediff popped on Tuesday after an upbeat Barron's article detailed the profitless Indian portal's attempt at hopping on Groupon's coattails by rolling out a flash-sale site in the world's second most populous nation.
