When a majority of the A/D lines are below their weekly and daily WMA's, it points to a serious market decline. When this occurs it is important to look at the other A/D lines to see if there are additional warning signs. If the weekly Stocks Only A/D line had also formed a negative or bearish divergence, it would be a more serious warning. The S&P 500 A/D line (not shown) also made a new high last week and shows no signs yet of a top. The iShares Russell 2000 (IWM) was under pressure for most of the month and its weekly A/D line continues to decline, but there does not show any divergence between price and the A/D line.
