There is, of course. But, first, I guess FUD is always part of the market. I don't think we could ever remove it. Rumors or even news itself could cause FUD. FUD may be intentional or not. But FUD could only affect the market if people react to it. If people are well-informed; if they research, verify, analyze, and so on, FUD won't cause significant changes to the market. So you can actually contribute to lessen or even eradicate its impact. As mk4 said, accurate information and education are the keys.
