Apple plowed through a 454.08 Hidden Pivot midpoint with such ease yesterday (see inset) that more downside to D=432.76 seems all but unavoidable. While a strong, impulsive reversal from anywhere above it would put the stock back on track for at least $560 or so, we’ll plan on buying some out-of-the-money calls if the selloff gets within 0.30-0.50 of the correction target. Specifically, I’ll recommend buying four December 570 calls with the stock trading 433.15 or lower. My rough guess is that they will be selling for around $2.00 at that time, but we’ll be able to get a more accurate read as the stock approaches 432.76.  If the order fills, we can try to short some December 580 calls on a bounce for as much as we’ve paid for the 570s.  More immediately, with $18 of presumptive downside from here, day traders should continue to favor the short side. ______ UPDATE (September 18):  Yesterday’s rally was bullishly impulsive on the 15-minute chart (although not on the hourly), but I’m not ready to give up on the 432.76 downside target quite yet. _______ UPDATE (September 18, 10:26 a.m. EDT):  Okay, okay.  I’ll be ready to say ‘Uncle!’ when this nasty little monkey hits 469.19, creating an undeniably bullish impulse leg on the hourly chart. At that point, little will have been lost — only an opportunity to get long at a 432.76 downside target that had looked like a back-up-the-truck number to me — one that would have been buy-able with a dime stop-loss.
