|Figure 1 shows the daily price bar panel for Apple Inc. (AAPL). This panel shows the 200-day linear regression trendline (solid blue line) along with the upper 1 sigma channel line (red dotted line), the upper 2 sigma channel line (red solid line), the lower 1 sigma channel (green dotted line), and the lower 2 sigma channel line (solid green line). Besides their statistical importance, the red channel lines represent resistance lines and the green channel lines support. The bottom panel shows the on-balance volume (OBV) indicator. The top panel is that of the linear regression slope indicator and the next lower panel shows the R-squared indicator.|

|The price bar panel shows that from February through November, price has moved within the confines of the upper and lower 1 sigma channel lines, indicating a strong uptrend. The one exception is in June, when price moved down to the lower 2 sigma channel line in an extended correction.|
The linear regression slope indicator in the top panel provides more information about this supposed strong uptrend. Note that this indicator is starting to roll over at a lower level than when it rolled over in the February to April time frame. This sets up a linear regression slope divergence whereby the slope of the linear regression trendline is starting to become shallow, while price continues to make higher highs and higher lows. When divergences occur they normally do so just before a change in trend, so this current divergence is a warning of an upcoming change in the trend of AAPL from a long-term uptrend to a long-term downtrend.
The R-squared indicator in the next lower panel also shows that it is now lower than in March. This is an indication that the strength of the uptrend in AAPL has been weakening, while price has remained between the upper and lower 1 sigma channel lines.
The bottom panel of Figure 1 shows the OBV. This indicator has now made a new lower low, indicating selling pressure.
While the long-term trend appears to remain in a strong uptrend, the underlying condition, as identified by the supporting indicators, show that the long-term trend of AAPL is in a topping process.
|Figure 2 shows the upsloping 50-day linear regression trendline (solid blue line) along with its upper 1 sigma channel line (red dotted line), its upper 2 sigma channel line (solid red line), its lower 1 sigma channel line (dotted green line), its lower 2 sigma channel line (solid green line), and its lower 3 sigma channel line (dashed green line). Besides their statistical importance, the red channel lines represent resistance lines and the green channel lines support.|

|In addition, Figure 2 shows the daily price bars breaking downward below the lower 3 sigma channel line in early November, signaling a reversal in the intermediate-term trend from up to down. Upon breaking down below the lower 3 sigma channel line, this line of support turns into a line of resistance. During the next five trading sessions, price retested this new line of resistance, and after a successful retest, price began its selloff.|
The linear regression slope indicator in the top panel also shows a divergence at the intermediate-term trend warning of a change in trend. Note that in October, the linear regression slope indicator made a lower high compared to August, while price continued to move higher during this period. Further, note that in late November the indicator moved below its zero line to signal the actual reversal in trend.
The R-squared indicator measures the confidence in the trend and its strength. When the R-squared indicator moves above its critical level, it indicates that there is a 95% confidence level that the trend will continue. Note that on November 23, this indicator moved above its critical level to indicate that there is a 95% confidence level that the new intermediate-term downtrend will continue. Therefore, we should expect price to continue to make lower highs and lower lows.
The R-squared indicator also measures the strength of the trend. As long as this indicator continues to move in an upward direction, the strength of the new intermediate-term downtrend will continue to strengthen.
|This statistical analysis has shown that the long-term trend of AAPL is in a topping process. This analysis has also shown that the shorter- and intermediate-term trend has already reversed downward. Further, the analysis of volume has shown that price is currently under selling pressure. As a result, price should continue to work its way lower, forming lower highs and lower lows, while ultimately completing the long-term topping process and reversing the long-term trend down.|
