For Jonathan Krinsky, technical analyst MKM Partners, Apple's chart has become a heated battleground between bulls and bears.
The bears have something big going for them: Recent momentum. Apple shares have been trapped in a vortex of pain over the past year and a half, with lower highs and lower lows creating what Krinsky terms a "falling channel."
But he observes that Apple shares, which are up about 10 percent in the past month, have recently reached up to the top of this channel. And he believes that the stock is set to rise through the top of it, thanks to something else it has going for it: $90.
