Considerations
If you are active in a particular stock, it is imperative that you monitor your wash sales period before you repurchase the stock. After you have taken a loss, you need to be aware of the date you can repurchase a security and still recognize the earlier loss. Investors may find themselves unable to realize significant losses due to wash sales. If you re-purchase a security 30-days before or after you sold it for a loss, that loss is disallowable (and added to the cost basis of the new tax-lot).
