No. The only way you can do that is to get a confirmed out/sale by your broker. That has to be called in, usually an affadavit signed or voice confirmation, and they basically sell it for nothing to a clearing house - essentially it would be a complete loss. So - you wouldnt get the last price posted. In this status - I am not sure how the broker will clear out as I have never had one in limbo that I have tried. If they do - you would then be able to write off those shares sold.

Unless you need the loss to offset gains elsewhere - you may be better off selling other losses or wait. Reason being - if stock was tradi g - you could always wait 30 days and buy back. Here you can not. If/when it resumes trading - it will go up. If there is no company/revenues - there would be no reason to relist.

If you have an accountant - go over options with them.
