You are mixing two things, running/owning a company and investing your money in the stock market. If the main investors at Nokia simply was looking for a place to invest their money, they would be out a long time ago. Clearly they have other objectives. That objective is a genuine one, and it is to make Nokia a healthy company in the mobile industry, a top world wide producer of phones and services.
The private initiative and enterprise is king. The bean counters in the stock market means nothing, they are playing a whole different game.
