"The CEO is lying to you in that press release. The shipping vessel he claims the company is refurbishing was actually scuttled a year ago and is busy taking on a load of rust and barnacles."
Assume that all that is widely known at the time is that the company just issued such a press release and that BOP doesn't like the company. Let's further assume he's short a chunk of it.
BOP said the CEO is lying. Is that libel? If so, why? If not, why not?
