Elon Musk explained it:

"When the Pony Express was the fastest thing, people promised to buy in advance of the paperwork" adding, "no longer relevant".

He has had his run-ins with Shorters. And they tried it on Tesla recently and it cost them heavy in the same way. The process of shorting is immoral because people can use it to depress a stock that could be bought cheaply then asset stripped. Basically fuelled by a tissue of lies.

Methinks governments can be bought that way. Perhaps not for 4 years at the moment.

And for those not following Tesla, Musk, in reaction, sold (at profit) red shorts with the letters S3XY on the back. And the pun is that his cars are Models; S, 3, X and Y.
