|The bottom panel shows that on November 1, 2011, price broke down below the lower 3 sigma channel line to signal a reversal in the short-term trend of the DJIA from up to down. Following that breakdown, the DJIA rallied upward but reversed back down on November 9, forming a new lower high. |
Immediately, the DJIA rallied upward to test this new lower high and again formed yet a new lower high, after which the DJIA started to sell off and made a new lower low on November 17, confirming that a short-term downtrend was underway.
|Looking at the linear regression slope indicator, it too indicated that on November 9, the short-term trend had reversed from an uptrend to a downtrend.|
The R-squared indicator since November 1 has, however, remained below its critical level, indicating that the newfound short-term downtrend remains vulnerable for a reversal back upward. This indicator needs to move back above its critical level to lend confidence that the new short-term downtrend is here to stay.
|Looking at the diffusion index in the top panel, this index shows the number of stocks in a statistically strong short-term uptrend. The last time, all 30 of the DJIA stocks were in strong, short-term uptrends was back on October 14. From that date forward, the DJIA continues to make higher highs. |
The last higher high made by price was on October 27. However, at that time, only 19 of the 30 DJIA stocks remained in strong, short-term uptrends, creating a bearish divergence between the diffusion index and the price chart, forming a negative bias. Following the breakdown in price, when it fell below the lower 3 sigma linear regression channel line on November 1, the number of stocks in strong, short-term uptrends has remained below 10, with only two of the Dow 30 stocks currently in strong, short-term uptrends.
Looking at the diffusion index from mid-October onward, it is easy to see that the trend in the number of stocks in a strong, short-term uptrend has continued to fall: This is a bearish sign.
|The breakdown below the lower 3 sigma linear regression channel line was a signal that the short-term trend had reversed down. On November 9, when the linear regression slope indicator moved below its zero line, it also indicated that the DJIA had in fact reversed downward. Since then, the DJIA has formed a lower high and a lower low, also confirming the trend reversal from up to down. |
The one thing that stands in the way of having confidence that the short-term trend has indeed reversed down is the R-squared indicator. This indicator needs to move above its critical level to signal that, statistically, a 95% confidence level exists that the new downtrend will continue. Until this occurs, the newfound short-term downtrend in the DJIA remains vulnerable to a reversal back upward.
