SEC announces investigation, at least folks can buy or sell based on what they think it will uncover. Heck what if there isn't a problem and everything is ok. Shareholders have already been screwed big time.
No the SEC jumps in on their white horse and says "we will save you" and screws all the legitimate shareholders and saves the con artists that are short and naked shorting.
The bad buys with the company has already got their goodies already if they are truly a scam.
If the SEC announced a investigation - there would hundreds of posts about the company getting it resolved very quickly. Just like the posts I read after a suspension - it was a misunderstanding and the company will be trading very soon.
And it would allow the insiders to continue to provide more fraudulent information so they can dump more shares.
