May I ask for the source of that information, and can you or anyone else (shout-out to
@Hock1,
@Doggydogworld,
@brian45011,
@luvb2b) link to some sort of public document or article that shows or strongly implies that "Nasdaq Market Makers" (Nasdaq member firms - of which there are hundreds I believe), are allowed
unlimited short positions within the ~5 business days stock borrowing window?
I haven't found the U.S. rules (which is weird ...), but here are the European commodities market "Nasdaq Clearing" rules for margin requirements and collateral management:
Nasdaq Clearing - Collateral Management
"Intraday Risk Monitoring
Intraday risk reports are generated every hour (starting at CET 10:00 and ending at CET 18:00) or more often if deemed necessary. Each intraday margin calculation reflects any clearing participant’s change in exposure,
with updated positions and real time prices, during the clearing day. In case of a breach by a participant of the intraday risk limit, the Clearing Risk Management will issue a margin call."
"Intraday Margin Calls
Nasdaq Clearing has both the authority and the capacity to calculate and require intraday margin as a means of maintaining a desired level of margin coverage. The Rules and Regulations of Nasdaq stipulate that
the new margin requirement shall enter into force immediately and be met by the member no later than 90 minutes after the clearing house notified the clearing member that a new margin requirement has been calculated."
Pretty clear position size dependent Value-at-Risk rules for long and short sales, and margin is maintained electronically and goes up and down based on positions.
Are you suggesting that no such rules exist on the U.S. Nasdaq exchange, that any market maker or hedge fund that is member of the exchange (there's hundreds of them) is allowed a full business week of
unlimited short positions, with no margin rules and no risk management whatsoever?
If true then that's incredible - and might be worth for journalists (shout-out to
@ZachShahan) to follow up on.
