Dow Diamonds Still Holding Pitchfork Support

The recent advance in the Dow diamonds may lack a certain power, but pitchfork support is still holding and higher prices are expected.

Security:   DIA
Position:   Hold

The Andrews pitchfork is composed of three lines. For an upward sloping pitchfork, the first line starts from a reaction low (1) and the second two lines are based on a reaction high (2) and low (3) that form after the first reaction low. The lines extend up parallel to one another and mark a rising price channel.

The upper trendline marks an extreme, and movements above this line create overbought situations. The lower line represents support and a security should hold this line to keep the uptrend in place. The middle line can be used to judge the strength of the underlying trend. Uptrends that continually fail near the middle trendline lack a certain power and may be prone to failure.

On the 30-minute DIA chart, the Andrews pitchfork extends up from the late January low. The stock held the lower trendline on February 9 and again on February 11 (green arrows). The stock flirted with the middle trendline from throughout the advance, but failed to hold above and extend its gains to the upper trendline (red arrows). This shows that the uptrend, while still in place, lacks power, and overhead supply may be a concern.

Even though the current advance may lack power, the trend is clearly up and higher prices should be expected until this trend is proven otherwise. What would it take to prove otherwise? First, the stock would need to break the lower pitchfork trendline. Second, the stock would have to break the February 9th low (106.65). Note that there is a consolidation from February 7 to 10 and then a breakout in February 11 (green box). This consolidation now acts as a support zone and a move below consolidation support would be short-term bearish.
