The fraction of the overall market that is participating in the market's up or down move. see also advance/decline line.
Relates to the number of issues participating in a market move. The move can be either up or down. As a rally develops, and the number of advancing issues is declining, the rally is suspect. As a decline develops, and the number of declining issues falls, the decline becomes suspect.
A measurement calculated by comparing the number of advancing stocks to the number declining. The more net advances seen in an up market, the greater its breadth; vice versa for down markets.
This is one of those technical terms you might hear mentioned in a trading room. It simply demonstrates how broadly a market is moving. When three-quarters of the stocks on the New York Stock Exchange, for example, rise during a given day, an observer might say the stock market had good breadth. Often, observers will measure the number of stocks advancing against the number declining as one way of monitoring breadth.
The percentage of stocks advancing relative to those unchanged or declining.
The amount of stocks that are up compared to the amount of stocks that are down on any given day.
The net number of stocks advancing versus those declining. When advances exceed declines the breadth of the market is inclining. When the declines exceed advances the market is declining.
