Fascinating chart from Ron Griess of The Chart Store. In order to qualify, the SPX must rally at least 10%, and then continue without a 10% correction:
The following table has a listing of all S&P Composite swings up of greater than 10% without a corresponding down swing of at least 10% where the up swing was at least 30%. The list is sorted by greatest % Move, in descending order and lists all up swings of 30% or more from 1928 to the present from Chart 14 above.
