As long as the 10 week average (blue dotted line) is rising above the 30 week average (red solid line) the odds are in favor of my being invested long. Compare the pattern during the 2022 decline to the advance that began in March 2023. The gray line is the weekly close, which can give me advance warning of a possible change in trend.
The GMI, which is Green, also indicates a longer term up-trend. Note in the chart and the table below that QQQ’s 10 week average has been above its 30 week average for 57 straight weeks!
