Above we see how the indicators have been weakening (kudos to Decision Point for the charts). New lows among NYSE common stocks have expanded beyond their March levels (top chart; click for greater detail); the advance-decline line for NYSE common stocks (bottom chart) has also been making new bear market lows.
Notice in the bottom pane of the second chart that the volume-weighted advance-decline line for NYSE common stocks has been much weaker than its traditional counterpart. This suggests that stocks are falling on higher volume than they're rising: just another sign of institutional bearishness.
When indicators and sectors are in gear, we have a trending market. Distinguishing trending markets from ones that are likely to reverse is one of the great challenges of trading at any time frame. Knowing what markets "should" do based on precedent--and observing what they *are* doing--is helpful in making the distinction.
