The supply and demand for a commodity, stock, or anything else that is highly volatile depending on the information available in the media. Suppose, for example, there is a revolution in a major oil exporting country. This may drive the price of oil higher without any change to the fundamentals of the market. In this sense, oil may be said to be traded in a news-driven market.
