That depends.If you have a capital gain for the year and need a tax loss to offset it then I would look at my worst investments and cut the loss to keep my capital gains down.
I am sure there are some with big gains this year but I am betting there are many times holdings losses that need no more tax losses for the year.
I am holding to see what they say and do going forward.You and all other must figure out what is best for yall.
