ONP, but wait a minute. Are you guys telling me that Muddy waters can issue such a "report" and that's legal? I mean what happens if none of their allegations materialize over time? Are they then getting troubles with the SEC? Please don't tell me they can do this and have nothing to fear in case this is all a big joke. That would be criminal.
It is disheartening that an unknown outfit with probably unsubstantiated allegation can move the stock price so dramatically. The FUD (fear, uncertainty, and doubt) factors overwhelm the common senses in a irrational market.
SEC should definitely step in with an official investigation in this case. Either a security fraud is committed by ONP or there is an illegal manipulation by Muddy Waters (and its backer in street.com.)
Note - I do not own ONP, although I traded it extensively last year.
