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 then 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 regularly. Additionally, StockCharts uses dividend-adjusted data for its calculations, while other sources may use non-adjusted data.
Advance-Decline Percent (AD Percent) is a breadth indicator that measures the percentage of Net Advances for a particular group of stocks, such as an index or ETF. Net Advances equals the number of advances less the number of declines. AD Percent equals Net Advances divided by the total number of stocks in the group, fluctuating between -100% and +100%. Chartists can use this indicator to create oscillators and the AD Line.
