I will have to use the Apple Inc. (AAPL) chart I’ve posted today in my next book, as a textbook example of a powerful, stair-step uptrend in a Point and Figure format.
Let's notice that the current upleg from 544 to 551 is a vertical up-column of Blue X's, which is still the primary influence within a one-way advance.
That said, however, a print of 548 will trigger a down-column of Red O's, which will tell us that AAPL's extreme near-term trend has morphed into a two-way trade.
Only a print of 543 will damage the uptrend. Barring such a print at 543, let's see if AAPL can muscle its way above 544 to a 545 print, which will be consider another P & F breakout that will project to 560-561, on the way to 570.
