"Thank you for contacting FINRA’s Office of the Ombudsman. Regarding your question, it would be incorrect to assume that short sales comprise 32% of the total volume on that trading day for IPIX . FINRA publishes the daily short sale volume pursuant to an SEC mandate; however, there are various trading anomalies that result in the reported short sale volume often being exaggerated. Thus, the true total short sales volume may be significantly lower than the volume that is reported. Third parties sometimes ignore this and try to claim the ratio is valid to further their own objectives. "
