You can see that AAPL triggered a buy signal on 3/11/08 when it broke the first internal channel trendline. Its accumulation base created a breakout price objective of approximately $165.
Given that it reached a high of $159.69 on 4/7/08 after four consecutive higher low swings within its upward channel, and that the current reaction (pullback) is greater than the previous five reactions in both time and distance, then Iâd say the odds of a pullback to at least the lower channel trendline in the $135ish area is reasonable.
