Fosback Absolute Breadth Shows a Quiet Market
Years ago, analyst Norman Fosback hatched the idea of looking at the absolute value of the daily breadth (A-D) numbers. He discarded the direction, i.e. whether it was positive or negative, to just look at how big the numbers were in recent days.

Market Breadth Data Notes
- We use WSJ/Barron's data for our final breadth numbers. Calculations made on numbers from other sources will show a slightly different result.
- We wait until late in the day in order to have access to the "final" numbers.
- This reflects final readings for the indicators covered.
- Values for indicators calculated using preliminary numbers released just after the close usually differ slightly from these numbers.
- We usually recommend that readers keep their own data for themselves, but this is a useful way to check and see if your numbers agree with ours.
