Markets Running On Dangerously Weak Breadth

 | Sep 13, 2022 02:11

  • The percentage of S&P 500 stocks trading above their 200-day moving average has reached a low 36%
  • The benchmark stock index has been below its 200-day moving average for five months now—its longest streak since 2009
  • Only 28% of NASDAQ Composite stocks are above their 200-EMA 
  • Market breadth refers to how many stocks participate in a given move in an index or on a stock exchange. We can interpret it based on two assumptions:

    1. The number of stocks going up relative to the number of stocks going down in an index.

    • Positive market breadth: the number of rising stocks is greater than the number of falling stocks. For example: if an index has 60 stocks if 40 are going up and 20 are going down.
    • Negative market breadth: the number of stocks going down is greater than the number of stocks going up.
    • Neutral market breadth: if the ratio of rising and falling stocks is not substantially different. For example, an index has 100 stocks, 52 are up, and 48 are down.

    2. The percentage of stocks in an index trading above their moving averages.

    • The lower the percentage of stocks above the 200-day moving average, the weaker the index is.

    That is what is happening right now. The percentage of S&P 500 stocks above the 200-day moving average is down to 36%, NASDAQ Composite stocks are down to 28%, and Russell 2000 stocks are down to 29% (in August, the percentage was 86%).

    In addition, the S&P 500 has been below its 200-day moving average for five consecutive months now, the longest streak since May 2009.
