S&P 500 Advance-Decline breadth line achieves a new all-time high today -- by a slight margin
* based on only the 2015 history, when the A-D breadth line tests its daily 50,2 upper Bollinger Band, a breadth and price pullback for the SPX index takes places within 1 to 7 trading days ... while a much different chart event took place in the October to mid-December 2014 period when the Bollinger Band width expanded throughout that period (see chart #2)
chart #1 - marks today's A-D new all-time high with a brown H line
chart #2 - XLK A-D breadth line also achieved a new all-time high today
