Short interest is the total number of shares of a particular stock that have been sold short by investors but have not yet been covered or closed out. This would also apply to shares marked short by regulation and have simply not settled.
What is being represented is that this short interest are naked short sales subject to squeeze which is not the case. Quite the opposite. The way the system works there is always going to be a short interest which is simply trades pending settlement. Considering this and the fact that MRIB hovers around 500,000 short interest most months there is most likely no naked short sales whatsoever, just short marking until delivery and settlement.
It's moot anyway. Even if all shares were settled the short interest represent less than 0.1% of the stock. Hence the myth of short selling is again debunked.
