requires brokers and dealers that are participants of a registered clearing
agency[8] to take action to close out failure to deliver positions. Closing
out requires the broker or dealer to purchase or borrow securities of like
kind and quantity. The participant must close out a failure to deliver for a
short sale transaction by no later than the beginning of regular trading
hours on the settlement day following the settlement date, referred to as T+

在发生fails to deliver后的第4天(T+4),参与的清算机构(券商等)必须将做空的
仓位平掉
第二个时间点:
If a participant has a failure to deliver that the participant can
demonstrate on its books and records resulted from a long sale, or that is
attributable to bona fide market making activities, the participant must
close out the failure to deliver by no later than the beginning of regular
trading hours on the third consecutive settlement day following the
settlement date, referred to as T+6. If the position is not closed out, the
broker or dealer and any broker or dealer for which it clears transactions (
for example, an introducing broker)[9] may not effect further short sales in
that security without borrowing or entering into a bona fide agreement to
borrow the security (known as the “pre-borrowing” requirement) until the
broker or dealer purchases shares to close out the position and the purchase
clears and settles.
In addition, Rule 203(b)(3) of Regulation SHO requires that participants of
a registered clearing agency must immediately purchase shares to close out
failures to deliver in securities with large and persistent failures to
deliver, referred to as “threshold securities,” if the failures to deliver
persist for 13 consecutive settlement days
如果fails to deliver持续了13天,并且已经在Threshold List中,则清算机构必须平
仓使得其从Threshold List清掉。

按照它的发行股65.20M算,它应该早就出现裸卖空,也就是发生fails to diliver。发
生fails to diliver后,按照它的做空量应该很快就会进入Threshold List里,GME是
