Cycles of the Standard & Poor's Composite since 1932

Chart 1

We have isolated 18 completed swing cycles and the first half of the nineteenth swing cycle on this chart. We also show our interpretation of four completed secular cycles and a fifth in progress. Each secular cycle is measured from bottom to bottom, and they vary in length from 826 weeks (15.88 years) to 904 weeks (17.38 years). The following chart and table provide more details on the various sub-cycles.
