Allis 7040 - 9/8/2015 21:56 The Median Line and George Marechal From this point we need to consider George Marechal, a chartist for which there is very little known other than he was a friend to both Roger Babson and Alan Andrews and that he authored one of the most amazing charts known. In 1933 incoming US President Franklin D Roosevelt reached out to Babson for a forecast for the US stock markets for the near future. Babson in turn consulted George Marechal who prepared a 15 year forecast from 1933 to 1948. So confident was he in the accuracy of his prediction that he had the chart copyrighted at the time. The chart you see below is the Marechal prediction, the upper line representing his forecast and the lower the actual performance of the Dow Industrials over the period 1933-1948. Pause for a moment to consider that this prediction encompassed 15 years and a World War not even yet on the horizon... Marechal's exact method died with him but what is clear is that he was using a version of Babson's Normal Line. The annotations added by his friend Alan Andrews show that he plotted turns with what are now known as Median Lines. With Median Lines we step closer in the evolution towards the Andrews Pitchfork.
