NICK SHERRY: Arising from the recent market turbulence, concerns have been raised that some market participants both here and abroad have been spreading false or misleading information in respect of certain securities.

This practice is sometimes referred to as "rumourtrage" and numerous members of corporate Australia have raised examples of this with me over the last year, some minor but I'd have to say, some simply shocking that in normal times people would shrug their shoulders and not take any particular notice of.
