The Final 20 Days of a Bull Market

As shown in the chart below, bull markets tend to end with a crescendo of buying.  The chart highlights the percent change in the $SPX or $DJIA in the final 20 trading days leading up to bull market peaks.

In the 10 bull markets post World War I, the final days of a bull have seen relatively large increases in equity indexes.  The median change in the index in the 20 trading days prior to the peak is 5.5%.  That’s considerably higher than the 0.8% median 20 day change on all other days.

Needless to say, there are plenty of occurrences in which the indexes are up this much over a 20 day period without signalling a bull market peak, so apply this data with care.  However, it’s worth keeping this history in mind as something to be on the lookout for at a turning point.
