Short-Term or Long-Term Capital Gain or Loss
As a general rule, you determine whether you have short-term or long-term capital gain or loss on a short sale by the amount of time you actually hold the property eventually delivered to the lender to close the short sale.
While the example given earlier in the pub was for a short-sale that resulted in a loss, the IRS doesn't care.
It's the fact that you only held the stock for as long as it took to hand it over to the broker (a day or less)...
And since it was a day or less, even tho the entire transaction was 366 days or more, it's NOT qualifying for long-term gains.
