Right, but you have an obligation to move to dismiss or to file an answer denying the allegations. If you do the latter, I strongly encourage you to also bring in your broker as a third-party defendant.
If sued for buying shares on the retail market, I would also file an NASD complaint against your broker for selling you counterfeir shares.
Fraud requires proving certain elements. First, there must be a misrepresentation. Second, that misrepresentation must be material. Third, they are required to justifiably rely on the misrepresentation. Fourth, there must be damage as a proximate result. There is no possible way for a retail to be found liable for fraud.
