單股股票可以多次做空嗎?

具體例子:

想像一下,我們有五個人,他們的動機如下:

Person A owns a share of company ABC and wants to lend it out to collect interest.  
Person B wants to short one share of company ABC.  
Person C wants to own one share of company ABC and lend it out to collect interest.  
Person D wants to short one share of company ABC.  
Person E wants to own one share of company ABC.  

然後發生以下情況(按順序):

Person A lends their share to Person B  
Person B sells their share to Person C  
Person C lends their share to Person D  
Person D sells their share to Person E  

這將導致 3 個每股一股的多頭頭寸和 2 個每股一股的空頭頭寸,均基於一股“真實”股份。如果允許上述情況,您可以想像這種情況無限發生,允許無限多頭和無限 - 1 個空頭頭寸,只要淨額等於一份多頭份額。

這可能嗎?是否有任何監管或程序系統來防止上述情況發生?

是的,股票可以多次出借和賣空:

如果賣空者從一家券商借入股票並賣給另一家券商,那麼第二家券商可以將這些股票借給另一家賣空者。這導致相同的股票被計算為“賣空股票”的兩倍。

許多 GameStop 的賣空股票可能已經被借入、出售和再次借入,從而產生了 100.6% 的賣空與流通股比率。

這種情況很少發生,但以前也發生過。

… 根據 Frank Fabozzi 的《*賣空》*一書,Palm 在 2000 年中期達到了 147.6% 的峰值空頭利率。
