Baidu posted a slight fourth-quarter drop and warned investors its profit won't grow this year either, as the Chinese Internet search engine boosts efforts to capture more of the country's surging mobile market. Shares rose 3.5% to $178.92.

Italian eyewear maker Luxottica Group SpA (LUX, LUX.MI) said its net profit fell 65% to EUR25.9 million ($35.5 million) in the last quarter of 2013 due to a tax audit that resulted in increased charges of EUR26.7 million.

Shares fell 0.8% to $15.36.
