NOK, ALU, ARMH, STM sell off after European markets decline

• European tech firms Nokia (NOK -2.5%), Alcatel-Lucent (ALU -4.4%), ARM (ARMH -2.8%), and STMicroelectronics (STM -2.6%) have sold off following broad declines for continental exchanges.
• The U.K.'s FTSE 100, France's CAC 40, and Germany's Deutsche Borse have respectively fallen 1.2%, 2.6% and 3.2%, and the EURO STOXX 50 index has dropped 2.7%. Over in the U.S., the Nasdaq is down 0.9%, and the S&P 0.7%.
• The selloff has come amid a 1.5% gain for the euro against the dollar, continuing a recent rebound. The euro/dollar exchange rate is back up to 1.11. It has also coincided with sharp increases in European debt yields.
• Nokia reports earnings tomorrow morning, and merger partner Alcatel-Lucent (past deal coverage) on May 7. ARM rallied last week in response to a Q1 revenue beat driven by strong royalty growth.
