I read somewhere that these hard to borrow stocks can be shorted if you have an account over $100,000 and contact your broker for approval. Perhaps contact your broker to see if they have any info on this.
I did call Fidelity before my last post. They said I could short as many as I wanted to, no problem. Wait until you see the numbers for April 15th when available on about the 24th. It isn’t going to be several million but will be 1million or more.
