Nokia Corp.'s (NOK, NOK1V.HE) stock price--up more than 90% since the company announced the sale of its handset business to Microsoft Corp. (MSFT)--is "clearly overheating," warned research firm Bernstein.

"We recommend investors avoid the name," said Bernstein. Shares fell 1.3% to $7.36.

A coming vote for control of the board of Telecom Italia SpA (TI, TIA, TIT.MI) could finally dispel confusion over the strategy of the Italian telecom giant, allowing it to forge ahead with a major investment plan aimed at facing the country's "hypercompetitive" telecom market, Chief Executive Marco Patuano said in an interview with The Wall Street Journal on Tuesday. Shares slipped 2% to $9.31.

The Asian index fell 0.6% to 143.73.

However, steelmaker Gerdau SA (GGB, GGBR3.BR, GGBR4.BR) posted gains amid expectations for strong sales of long steel as Brazil beefs up infrastructure ahead of the 2014 soccer World Cup and 2016 Summer Olympics, both of which it will host. Gerdau shares rose 3% to $7.95.
