The forged signature is very serious, and that typically gets the SEC's attention. However, it is not typcially something that would result in the stock's suspension. Or result in any other overt and public action on the part of the SEC and/or FINRA that would result in you or anyone else knowing if the SEC is investigating.
Mid-2011 is only a year ago. Since SEC investigations can take up to 5 years (but average around 18 months), it is still quite likely that the SEC, if they are investigating, is not yet done.
You may see some action before this is all over. Don't write it off yet.
