Macquarie Securities announced yesterday that Nokia may publish a profit warning. The sell-off started and immediately NOK went down -6%. Today, as the profit warning was not released and Nokia spokeswoman said that the company did not comment on market rumors, Macquarie told that the profit warning may come next week. ;-)
Nokia stopped outsourcing in the late 2008. It began again this spring. I think that Nokia has such good tools for monitoring the transactions that they would have published it, if there is a reason for it.
