It is against U.S. securities law to knowingly make false statements or publish false information about a company you are shorting (selling stock now and buying the shares later, hence betting the stock price will go down). In other words, you can’t try to drive the company’s stock price down you are shorting so you can profit from the trade. Besides being illegal, the practice is unethical. Just go to Kant for that! The guy was fanatical against lying.
