Figure 1 shows the daily price bars of Apple (AAPL) in the bottom window. The top window shows the linear regression slope indicator and the middle window the R-squared indicator. |
FIGURE 1: AAPL, DAILY. This chart shows the daily price chart of Apple, stock symbol AAPL, in the lower window along with its 200-day linear regression trend line and its associate channel lines. The top window shows the Linear Regression Slope indicator followed by the R-Squared indicator in the next lower window. |

Note that the linear regression slope indicator in the top window has crossed below its zero line to indicate a reversal in trend from a long-term upward trend to a long-term downward trend. |
The R-squared indicator in the middle window shows it has crossed above the critical level to indicate a statistically significant upward trend. A statistically significant trend is one that has a 95% statistical confidence level of continuing. |
The bottom window shows the daily price bars of AAPL. This window also shows the 200-day linear regression trend line (blue line) along with the upper 1 sigma channel line (red dotted line), the upper 2 sigma channel line (solid red line), the lower 1 sigma channel (green dotted line), the lower 2 sigma channel line (solid green line), and the lower 3 sigma channel line (dashed green line). The red channel lines represent resistance lines and the green channel lines represent support. |
In the bottom window notice that price broke down below the -3 sigma channel line. This signals that a reversal in the long-term trend from up to down was in progress. The reversal was complete once the linear regression slope indicator moved below its zero line and the R-squared indicator moved above its critical level in late January 2013. Thus, Figure 1 shows that AAPL has reversed its long-term upward trend and is now established in a long-term downward trend. Notice that both the linear regression slope indicator and the R-squared indicator continue to point in the downward direction indicating that the downward trend has further to go. |
