Carry the loss back two years against prior taxable gains and get a refund in April, or carry the loss forward indefinitely to claim against taxable capital gains in the future.
Buy it back in January at a price higher, or lower, or the same as you sold, If You Decide to in 30 days, or don't.
Either way, you're starting all over with a tax "credit" in your pocket.
Regardless of if you buy this back, or you buy something else.
