Hi (columbia)
That is a good point that every one has had to re-adjust to the present market and as some have done here with UMC they have sold at a loss and put their money into other companies who they think are going to make them money quicker then UMC.
At the rate UMC share price has been going it is going to take quite some time to get back to $2.50 again.
