StockCharts uses a three-step process to calculate breadth indicators. First, StockCharts maintains component lists for these indices. Second, our scan engine uses these component lists to run scans based on the price data for the individual stocks. Third, the data is updated and published to our website.
This “in-house” data may differ from other sources due to differences in the index components and price data. Index components change and require updates on a regular basis. Additionally, note that StockCharts uses dividend-adjusted data for its calculations, while other sources may use non-adjusted data.
The chart example below shows Nasdaq 100 Record High Percent ($RHNDX) as the gray line, a 20-day moving average as the red line and the Nasdaq 100 in the bottom panel. Chartists should consider using a moving average to smooth the data, as Record High Percent can be a volatile series. The Nasdaq 100 was added because it is handy to plot the underlying index along with the indicator.
