As an illustration, I have collected headlines regarding the US dollar / Euro exchange rate for the last thirteen days (source CNBC.com). What we see is a succession of headlines (and stories) that talk about dramatic upward and downward movements of this exchange rate. There are days where one can even get three headlines on this subject, each of them pointing in a different direction. The list of headlines is below, together with a plot of what the Euro/Dollar exchange rate did during those days. Interestingly, despite the dramatic tone of the headlines the exchange rate was very stable moving in a range 1.4350 to 1.4500 (which is a fairly narrow range for this exchange rate).
