Hurst indicated that a CENTERED MOVING AVERAGE was a 
    proper
    method of examining cyclicality in a price series -- I 
    agree.
     
    The attached shows two relative long term (186 weeks--3.6 
    years and 386 weeks
    --7.4 years).  These lengths are taken from of MEM 
    evaluation of cycles in the
    DOW weekly data.
     
    The attached pictures show just how far this approach can 
    project into the
    future and whether it is correct or not remains to be 
    seen.
     
    In evaluating studies of this length we can only examine 
    if the behavior of
    prices lie within a series of "bands" which we calculate 
    around the Centered
    Moving Average of prices and the Fourier projection of the 
    selected period
    of cyclicality.
     
    LOOK HARD AT THESE RESULTS.
     
    This approach is not yet a "commercial" product.  Any 
    feedback as to whether
    this approach has merit would be appreciated.
