The large cap indexes have been under pressure for some days but the Nasdaq and small caps are doing well. This is reflected in the breadth.
The T2108 is Worden indicator that tells you % of stocks above 40 day moving average. As you can see below the indicator rose sharply after reaching around 23. At a current reading of 59 it shows that 59% of the stocks are trading above their 40 day moving average. That is a healthy breadth picture.
$BPNYA is another breadth indicator. It tells you % of stocks that are in confirmed up trend using the pint and figure charting method. Currently 73% of the stocks are in confirmed uptrend. The indicator in recent days has dipped below its 5 day moving average indicating pullbacks or reversals on some of the stock.
The Stockbee Market Monitor is my own breadth based market timing model. Currently the model is in transition mode indicating excessive bullish breadth which often leads to pullbacks in next 2 to 3 weeks.
