Week in review: Rosetta Stone’s earnings; Microsoft sparks EU antitrust probe of Google

As quarterly earnings season winds down, Rosetta Stone, maker of language-learning software, provided a nice surprise for investors.
The Arlington, Va.-based company posted fourth quarter results that easily beat Wall Street’s estimates. The stock rose 27% on Friday to close at 22.
Another big story this week was the European Union opening a preliminary antitrust investigation into Internet search giant Google’s business practices. Microsoft played a significant role in prodding the EU to act.
