发帖数: 14294 | 3 Currently, reporting of short sales positions is not mandatory, and few
funds opt to do that. There are occasional news stories that some big-shot
discloses a sizable short position in 13F-HR, for whatever reasons.
The "How" part seems a trivial one. Just add additional line items to the
13F-HR. Make it mandatory if the $ value of short positon on a ticker
exceeds a minimum threshold.
Now let's get to "Why."
The stock market has the same systemic risk as the trust cmpanies in the
1920s~1930s and the shadow banking prior to the recent financial crisis. Such
systems, where participants can freely withdraw their stakes, are vulnerable
to the classic bank-run attack. Short sellers love to take advantage of
this vulnerability. Once the withdrawl momentum builds up and panic ensues,
the system will fall, with or without a legit reason. Turmoils of this
nature unnecessarily hurts the real economy and disrupts the overall welfare
of the society. Long positions reporting is already mandatory by big funds.
It seems to make sense short positions follow the same reporting requirements.
