Despite a few negative dips, Nasdaq 100 High-Low Percent ($NDXHLP) has been mostly positive throughout 2013. The red arrows show the brief, and shallow, dips into positive territory. Last week's dip did not last long as High-Low Percent surged to 15% this week. A downtrend is pretty much impossible until Net New Highs exceed -5%. Note that StockCharts calculates High-Low Percent for several indices and the nine sector SPDRs.
