The share prices of RIMM, NOK and AAPL in the last 12 months. This is telling:
RIMM and NOK moved almost in tandem up to 15 days ago.
It appears first 350 days of their price movements can't be explained by their fundamentals because the two companies did different things. It has to be market sentiment then?
By the way, AAPL is getting more interesting everyday.
