I discussed this with another trader i know last week....He was hoping for the old "JANUARY" affect....but there's one problem:
IN the late 90's people MADE huge money and then would sell all their losers in December for tax purposes, and would often buy them back in January....ex: you owned dell at 30...it was 27 in December....sell it , write the loss, wait 30 days and buy it back as a long term hold at 28 or so.....the problem is, everybody has losses....there's no longer huge gains and tax liability to off set. Could be quite some time before we see that again.
