GLOSSARY

Advance/Decline (A/D) line An A/D line is constructed from a cumulative plurality of a set of data over a specified period (usually daily or weekly). The result is plotted as a continuous line. The A/D line and market averages usually move in the same direction. Failure of the A/D line to confirm a new high in the market average is a sign of weakness, whereas failure of the A/D line to confirm a new low by the market averages is a sign of technical strength.

Advisory services Privately circulated publications that comment upon the future course of financial markets, and for which a subscription is usually required.
