Nokia (NYSE: NOK), the premier company in the wireless industry, has shown investors recently that even one of the best-run businesses in the world can have problems. The stock has fallen from above $60 to $40 per share in the last month. In my opinion, it's happened in large part because investors created a scenario of perfection that no company should be held up to.

The problems at Nokia are as follows: First, management surprised investors by issuing a profit warning based on product delivery problems. I think that was an error. Nokia should've planned its release schedule better, and alerted the marketplace sooner. Not doing so caused havoc for customers and retailers waiting for new wireless models. And, it raised questions among investors about Nokia's communications strategy and risk management. I don't view this as anything approaching a terminal problem, but Nokia needs to do better in the future.
