h3 Does Volume Complement Or Contradict Bullish Analysis?

An August 19 analysis outlined a long-term bullish signal for stocks that has occurred only ten other times in the last thirty-five years. Have we seen any other long-term signals in recent weeks? The answer is yes.

A Trend Change In Up/Down Volume?

The chart below shows up/down volume (1996-2010) for the NYSE Composite Stock Index, along with its 50-week moving average (thick blue line).

Notice how all-things-being equal, the probability of bad things happening increases when the 50-week moving average is flat or negative (see orange and red arrows below). Conversely, the probability of good things happening increases when the 50-week moving average turns back up in a bullish manner (see green arrows below). The S&P 500 is shown at the bottom of the image below for reference purposes.
