AD Percent for the S&P 500 dipped below -90% on Monday and this was the sixth reading below -90% this year. AD Percent equals advances less declines divided by total issues. Thus, if 25 stocks advance (5%) and 475 stocks decline (95%), AD Percent equals -90% ((25 - 475)/500).
The chart below shows the S&P 500, S&P 500 AD Percent and the S&P 500 AD Line. The index fell 11 of the last 14 days and recorded new lows the last four days. AD Percent joined suit with negative readings 13 of the last 14 days. Thus, AD Percent was negative even when the index closed higher on December 10th and 18th.
