RE:Shorts killing this Stock Mr. Duck, once again your quacking is all screwed up and very wrong.
A "naked" short sell is where you are selling something you don't. It is wrong in my opinion, because if you tried to sell a car or house you didn't own you would probably land up in jail.
But a "short sale" against something you do OWN is a common tactic as insurance against a holding suddenly dropping. Valid tactic and used commonly even among yours truly who does not short individual stocks but indexes and futures. See below definition.
Again I think you are better served going to a pond with the crypto kids. They are so screwed up (one of my friends kids just lost $45,000 even though I told him to bail weeks ago). Who knows with your negative quacking you might be able to scare some of them there unlike here.

"A short sell against the box is the act of short selling securities that you already own, but without closing out the existing long position. This results in a neutral position where all gains in a stock are equal to the losses and net to zero. "
