Shares in the world's top mobile phone maker Nokia plunged nearly 11 per cent on Wednesday after it slashed its second-quarter and full-year forecasts for its key devices and services unit.
"During the second quarter 2010, multiple factors are negatively impacting Nokia's business to a greater extent than previously expected," Nokia said in a statement, citing the competitive environment for expensive cellphones and shifts in product mix towards "somewhat lower gross margin" phones.
Nokia said it expected sales in the devices and services unit to be "at the lower end of, or slightly below" the 6.7-billion-euro (8.2-billion-dollar) to 7.2-billion-euro range it had previously given for the April-June period.
It said the unit's operating margin would also be at the lower end or slightly below the range of 9 to 12 per cent previously given for the second quarter, and in the full year it would be at the lower end or below its previously given target of 11 to 13 per cent.
For the full year, Nokia said it expected its mobile device value market share to fall slightly from 2009. It had previously forecast a slight increase.
Shares in Nokia were slammed on the news and by 1230 GMT traded 10.98 per cent lower at 7.06 euros on a Helsinki bourse down about two per cent.
The stock had already been shaken by market whispers of a profit warning that emerged last week. In June 2000, the shares hit an all-time-high of 65 euros in the midst of the dot.com bubble. Nokia is due to release its second quarter results on July 22.
