RE: Tax Loss Not necessarily Socastar,
You as an individual investor might prefer to take the capital loss in this fiscal year as opposed to next year because you have some gains to offset or maybe you are in a higher tax bracket this year then you will be next year. You still have to wait thirty days, to buy back the asset, in order to make the loss ligitimate and avoid the "superficial capital loss" ruling.
Additionally, if you did this as a cross trade, it might have been because you wanted to transfer those assets to another member of your family or corporate entity that is in a lower tax bracket than you are.
Good luck in your trades
