At which point does it become illegal though? Is it considered insider trading if you know about a security issue but have no internal knowledge about deals etc.?
I would hope that intentionally spreading false information to manipulate stock prices would be illegal, but it may be hard to draw the line between subjective interpretation, intentionally misleading interpretation, and outright lies.
