Regardless of market capitalization or volume, the A/D line represents all issues on the NYSE Composite equally. An advance in Wal-Mart (~$214 billion market cap) is just the same as an advance in NL Industries (~1 billion market cap). As such, the A/D line represents the "rank-and-file" or the masses within the NYSE Composite. |
There are two steps to calculating the A/D line. First, subtract declining issues from advancing issues. The amount will be positive when there are more advancers and negative when there are more decliners. Second, each day's reading is applied to the previous day to form a cumulative or running total. This is the A/D line. |

The A/D line foreshadowed the August reversal and autumn advance. Note that the A/D line formed a large positive divergence over the summer, and this preceded the early October breakout. By the time the NYSE Composite broke above resistance in October 2004, the A/D line was trading at a multimonth high (green vertical line). This showed broad strength within the index, and the advance continued for several months. |
The A/D line kept pace with the advance from September 2004 to March 2005, but a recent support break shows broad selling pressure. While the NYSE Composite is still holding above its January low (red arrow), the A/D line broke below its January low. This is not a negative divergence, but shows relative weakness in the A/D line and among the masses within the NYSE Composite. Relative strength in the A/D line preceded the autumn advance, and relative weakness could foreshadow a spring decline. |
