Well, there are falling stocks

Apple down 3% the last week (but up 44 % YTD)

and there are falling stocks

Nokia down about 7 % the last week and down 22% YTD

If things get worse and MS offers to buy Nokia as some have suggested than possibly Nokia stock will go up (but MS will probably go down).
If Nokia starts to turn it around and windows is selling than Nokia stock will go up.

So is now the time to buy?
