A wash sale occurs when you sell securities at a loss and within 30 days before or after the sale you buy or acquire substantially identical stock or securities. The amount of the disallowed loss is then added to the cost basis of the shares acquired. Wash sales are only tracked within the same symbol/CUSIP for 1099 reporting purposes. Please consult your tax advisor for any additional wash sale reporting obligations. For further explanation of a wash sale, please watch this brief presentation video.
