he website "http://forecasts.org" provides free forecasts with a time horizon of 6 months for the american economy. The availability of forecasts for the main currency pairs and of the indices of the main stock exchanges makes this information interesting for a general understanding of the world's economy.
Unfortunately no information is available on the methodology used for the forecasts and and on the error of the past forecasts. Anyway each prevision is composed by a forecasted value and a confidence band.
The chart below shows the expected behaviour of the Dow Jones Industrial Average. The blue line corresponding to negative months values represents the historical values (from http://finance.yahoo.com) of the index and the yellow line correspond to the forecasted value of the index.
The other colored lines show the confidence error of the forecast and must be read in te following way: there is the 25% of probability that the index value will be below the red line, and the 10% of probability that the index value will be over the gray line.
Another important parameter for the american economy is the exchane ration with the Euro shown in the picture below. In this case historical data are from the website "http://www.global-view.com" and the chart can be read as the previous chart.
