Any amendments to filed positions must be made via the SFC portal.
The only way to amend any position quantity, wrong stock code or wrong ReportingID is to re-submit the entire Reportable Short Position Form to supersede the previous submission straight in the SFC portal.
This is not a process available in Filing Manager.
Please take note, appropriate remarks including the reason(s) for re-submission and the previous submission reference number (for example, SFC12107PT238L) specified in the previous submission acknowledgement must be provided.
