".........sent Nokia shares on an unusual high....."
Therein lies the clue. Whenever a company is in trouble the market sharks try one of two strategies. Attacking a company's share price by various "shorting" tactics or pumping the share price by means of some form of market manipulation. One means to achieve the latter is to spread false rumours in an attempt to create an artificial increase in share value. This approach has been used three times in the last twelve months with Nokia stock. First it was MS themselves who were the alleged suitors, then it was Samsung and now Lenovo. The stripy shirted sharks appear to lack imagination.
