还有今天有一篇 I suspect the hedgies are illegally covering their short positions，基本认定空头头寸并没有减少，只是被非法掩盖了。"Assuming that XYZ (e.g. GME) is a hard to borrow security (e.g. apes holding strong), and that Trader A (Melvin), or its broker-dealer, is unable (apes again) to borrow shares to make delivery on the short sale of actual shares, the short sale may result in a fail to deliver position at Trader A’s clearing firm. Rather than paying the borrowing fee on the shares to make delivery, or unwinding the position by purchasing the shares in the market, Trader A might next enter into a trade that gives the appearance of satisfying the broker-dealer’s close-out requirement, but in reality allows Trader A to maintain its short position without ever delivering on the short sale. Most often, this is done through the use of a buy-write trade, but may also be done as a married put and may incorporate the use of short term FLEX options. These trades are commonly referred to as “reset transactions,” in that they have the effect of resetting the time that the broker-dealer must purchase or borrow the stock to close-out a fail. The transactions could be designed solely to give the appearance of delivering the shares, when in reality the trader has no intention of meeting his delivery obligations. Such transactions were alleged by the Commission to be sham transactions in recent enforcement cases. Such transactions between traders or any market participants have also been found to constitute a violation of a clearing firm’s responsibility to close out a failure to deliver."
