Exxon Mobil Long Term Trend Reversal?

Long-term statistical analysis shows that the Exxon Mobil long-term upward trend could be nearing an end with a long-term reversal downward a possibility.

Security:   XOM
Position:   N/A

The lower panel of Figure 1 shows the daily price bars of Exxon Mobil (XOM). This figure also shows the 200-day linear regression trend line (blue upward sloping 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.

FIGURE 1: XOM, DAILY. This chart shows the daily price chart of the Exxon Mobil, stock symbol XOM, in the lower panel along with its 200-day linear regression trend line and its associate channel lines. The top panel shows the Linear Regression Slope indicator followed by the R-Squared indicator in the next lower panel.

The linear regression slope indicator bottomed in November 2011 and rose in a period of price acceleration from November 2011 to May 2012. Following May 2012 the linear regression slope indicator started a long period of moving lower in a period of price deceleration. Price deceleration is typically the last stage of a trend before a reversal in trend sets in. Note that the linear regression slope indicator is still pointing downward and a move below its zero line will indicate a reversal in the long-term trend from up to down.

The R-squared moved above its critical level in February 2012 indicating a statistically significant long-term upward trend. By statistically significant, it is meant that there is statistically a 95% confidence level that the upward trend will continue. Notice that the upward trend has continued for more than a year. Also notice that this indicator is pointing downward and is close to moving below its critical level. A move below its critical level will indicate the lack of a statistically significant upward trend, making it vulnerable to a reversal downward.

Price has moved below its -3 sigma channel line indicating that a reversal in trend from a long-term upward trend to a long-term downward trend is in progress but not complete. A trend reversal is complete once the linear regression slope indicator moves below its zero line and the R-squared indicator moves below its critical level and then back above its critical level.

In conclusion, statistically the long-term upward trend remains in effect as long as the linear regression slope indicator remains above its zero line and the R-squared indicator remains above its critical level. With both of these indicators pointing in a downward direction, and price having moved below its -3 sigma channel line, it looks like a trend reversal from a long-term up trend to a long-term down trend is a possibility.
