For days you had shares available to short while it was going up past $16. Now today the shares are "HTB" and the stock is in a spiral down. Brokers once again have the shares short plain and simple. The same thing applies to UNG along with many other stocks.
Thats why everybody got out of stocks, its days are over. Let the #$%$ in Wallstreet play with thier own money, its all just an insiders only rippoff stealing money from middleclass America. No more. Let them rot.
